connect to the towing vehicle with a rigid towing

device. Do not use chains, cables or other non-rigiddevices for towing. Lock the hubs when towing is

completed.25. Keep body and hands away from pin hole leaks or

nozzles that eject high pressure hydraulic fluid. Use

cardboard or paper to find hydraulic leaks. Hydraulicfluid escaping under pressure can penetrate skin and

cause injury. Fluid accidentally injected into the skin

must be surgically removed within a few hours by adoctor or gangrene may occur.

26. Before any hydraulic system maintenance, stopengine and lower cutting units to the ground so all

pressure is relieved.

27. For major repairs or other assistance, contact yourlocal Toro Distributor.

28. To reduce potential fire hazard, keep engine area

free of excessive grease, grass, leaves and dirt.29. If engine must be running to perform maintenance

or an adjustment, keep hands, feet, clothing and otherparts of the body away from cutting units and other

moving parts. Keep everyone away.

IMPORTANT: Check oil after every 5 hours

operation or daily. Change oil and filter after the first

50 hours, then change both every 100 hours

operation thereafter. Change oil and filter more

frequently when engine is operated in extremely

dusty or dirty conditions.

5. Insert dipstick into tube and close and latch hood.

CHECK COOLING SYSTEM (DAILY)

The cooling system is filled with a 50/50 solution ofwater and permanent ethylene glycol anti-freeze.

Check coolant level at beginning of each day beforestarting the engine. Capacity of cooling system isapproximately 3.9 gal (14.7 l).

CAUTION

The best time to check coolant level is

each day before the engine has been

started because coolant system has not

been pressurized. When the engine is hot

and the radiator cap is removed, pressur�

ized coolant can escape and cause burns.

If engine coolant is hot, slowly and care�

fully remove radiator cap.

1. Unlatch, raise and prop hood open. Make surehood prop is secured in one of the mounting bracketson hood.

2. Remove radiator cap (Fig.5). Level of coolant mustbe above the radiator core and about 1 in. (25 mm)below bottom of filler neck.

3. If coolant level is low, add a 50/50 mixture of waterand ethylene glycol anti-freeze. DO NOT USE

ALCOHOL/METHANOL BASE COOLANTS OR

WATER ONLY. DO NOT OVERFILL.

4. Install radiator cap, close and latch the hood.

CHECK HYDRAULIC SYSTEM FLUID

(DAILY)

1. Fluid level should be checked daily through sight

glass at rear of hydraulic reservoir (Fig. 6). When oil iscold, level will be slightly below center, but should be inthe middle of the sight glass when the oil is warm.

Figure 61. Hydraulic Oil Level Sight Glass 2. Reservoir Fill Cap

2. If oil level is low, add hydraulic oil to the reservoir

(Fig. 6); refer to Machine Fluid Recommendations,page 8.

BEFORE OPERATINGFILL FUEL TANK

CAUTION

Because diesel fuel is flammable, use

caution when storing or handling it. Do not

smoke while filling the fuel tank. Do not fill

the tank while engine is running, hot, or

when machine is in an enclosed area.

Always fill fuel tank outside and wipe up

spilled fuel before starting the engine.

Store fuel in a clean, safety approved

container and keep cap in place. Use

diesel fuel for the engine only; not for any

other purpose.

1. Remove fuel tank cap (Fig. 7).

2. Fill tank to about one inch (25 mm) below bottomof filler neck with No. 2 diesel fuel. Install cap.

Figure 71. Fuel Tank Cap

CHECK TIRE PRESSURE (DAILY)

Since the Groundsmaster 580-D can be operatedunder many different types of turf conditions, propertire pressure is very important. Use the following as aguide:

Under Normal mowing conditions and when usedon a wide variety of turf grasses - 15 psi (103.4kPa) front; 13 psi (89.6 kPa) rear. 50 psi (344.7 kPa)castors.

When turf is wet and softer than normal - use lowpressure: 12 psi (82.7 kPa) front and 9 psi (62 kPa)rear.

When turf is dry and harder than normal, use

higher tire pressure: 18 psi (124 kPa) front andrear.

IMPORTANT: Do not operate in HIGH RANGE for

extended periods when tire pressure is less than 18

psi because tires may be damaged. When tire

pressure exceeds 18 psi, HIGH RANGE may be

used.

CHECK SYSTEMS OPERATION (DAILY)

Start engine. Move the Groundsmaster 580-D, slowly,to an area where the machine can be checked for

proper function. Check operation of controls, safetyinterlock system, engine, hydraulic system, brakesand cutting units. Refer to Know Your Controls andOperating Instructions sections for proper procedures.

CHECKING CUTTING UNIT MISMATCH

To assure all cutting units are at the sameheight-of-cut:

1. Adjust all cutting units to the highestheight-of-cut. Position all castor arm height-of-cutspacers to on the underside of the castor arms. Do notmove washers. Leave them in their original position.

Note: Unless all castor wheel axles are not in the samelocation, axles do not have to be relocated. All,however must be in the same holes (Fig.8).

2. Place a flat 4'x8' sheet of 3/4" plywood on a levelsurface and lower a cutting unit onto the plywood.

3. Taking each cutting blade in turn, position blade soit faces fore and aft. Measure from plywood to front tipof cutter blade and record dimension. All blade heightson same deck should be within 1/4" (6.3 mm) of oneanother. If blade heights meet criteria, proceed to

step 5. If blade heights are not within 1/4" (6.3 mm),proceed to step 4.

4. To match cutting blade height, transfer washersfrom one side of a castor wheel arm to the other. If endis to be lowered, transfer one or both washers from the

underside to the top. By contrast, if end is to be raised,transfer washer(s) from the top to the underside. Eachwasher is 1/8" (3 mm) thick. Repeat measurement ofblade tip height and record new dimensions.

5. Repeat steps 2-3 on remaining cutting units, and

step 4, if necessary. If washers are transferred on aoutboard cutting unit castor arm, be sure to transfer thesame number on both ends of the castor arm.

6. Compare blade height dimensions of all cuttingunits. Blade heights must be within 3/8" (9.5 mm) of

one another. If they are not, determine which cuttingunit height can be changed to compensate fordifference and either transfer washers from bottom totop to lower unit, or from top to bottom to raise. Transferan equal number of washers at all castor wheel

locations to keep cutting unit level - two on front unit,four on outboard units.

BEFORE OPERATINGADJUSTING HEIGHT-OF-CUT

The height-of-cut is adjustable from 1 to 5-1/2 in.(25to 140 mm) in 1/2 in.(13 mm) increments. Positioningthe castor wheel axles in the top holes of the castor

forks (Fig. 8) allows Low range height-of-cut settingsfrom 1 to 4 in. (25 to 102 mm); positioning the castorwheel axles in the lower holes of the castor forks (Fig. 8)allows High range height-of-cut settings from 2-1/2to 5-1/2 in. (63.5 to 140 mm).

Figure 8

1. Start engine, position the machine on a level

surface, lower cutting units to a point where castorwheels can be removed from arms, set lift levers inneutral, set parking brake and shut engine off. Removeignition key to prevent accidental startup.

2. Position castor wheel axles on all cutting units inthe same hole in the castor forks.

3. On the front cutting unit, remove the hairpin cotterand clevis pins from the rear castor pivot arms (Fig. 9).Align the pivot arm holes with selected height-of-cutbracket holes in the deck frames, insert clevis pins andinstall the hairpin cotters (Fig. 9).

DIAGNOSTIC LIGHT

The GM 580-D is equipped with a diagnostic lightwhich indicates if the electronic controller isfunctioning correctly. The green diagnostic light is

located under the control panel. When the electroniccontroller is functioning correctly and the key switch ismoved to the ON position, the controller diagnosticlight will be illuminated. The light will blink if thecontroller detects a malfunction in the electrical

system. The light will stop blinking and automaticallyreset when the key switch is turned to the OFF position.

Figure 261. Electronic Controller Light

1

When the controller diagnostic light blinks, one of thefollowing outputs has been detected in the controller:

1. One of the outputs has been shorted.2. One of the outputs is open circuited.

Using the diagnostic display, determine which outputis malfunctioning, refer to Checking InterlockSwitches.

If the diagnostic light is not illuminated when the keyswitch is in the ON position, this indicates that theelectronic controller is not operating. Possible causes

are:

1. Loopback is not connected.2. Fuses are blown.3. The light is burned out.4. Not functioning correctly.

5. Fusible links are blown

Check electrical connections, input fuses anddiagnostic light bulb to determine malfunction. Makesure loopback connector is secured to wire harnessconnector.

Note: If the diagnostic light flashes during normaloperation of the machine, do not turn off the machine,toggle to the output and touch any switch. The LED will

flash indicating the source of the failure.

DIAGNOSTIC ACE DISPLAY

The GM 580-D is equipped with an electronic

controller which controls most machine functions. Thecontroller determines what function is required forvarious input switches (i.e. seat switch, key switch,etc.) and turns on the outputs to actuate solenoids orrelays for the requested machine function.For the electronic controller to control the machine as

desired, each of the input switches, output solenoidsand relays must be connected and functioningproperly. The Diagnostic ACE display is a tool to help the userverify correct electrical functions of the machine.

OPERATING INSTRUCTIONS

CHECKING INTERLOCK SWITCHESThe purpose of the interlock switches are to prevent

the engine from cranking or starting unless the tractionpedal is in NEUTRAL, to ensure cutting unitsdisengage when raised or when operator leaves theseat. In addition, the engine will stop when the tractionpedal is depressed with operator off the seat.

THE INTERLOCK SWITCHES ARE FOR

THE PROTECTION OF THE OPERATOR

AND BYSTANDERS, AND TO ENSURE

CORRECT OPERATION OF THE MA�

CHINE, SO DO NOT BYPASS OR DISCON�

NECT THEM. CHECK OPERATION OF THE

SWITCHES DAILY TO ASSURE INTER�

LOCK SYSTEM IS OPERATING. IF A

SWITCH IS DEFECTIVE, REPLACE IT BE�

FORE OPERATING. THE CONTROLLER

HAS THE ABILITY TO DETECT BYPASSED

SWITCHES AND MAY PREVENT THE OP�

ERATION OF THE MACHINE IF SWITCHES

ARE BYPASSED. DO NOT RELY ENTIRELY

ON SAFETY SWITCHES - USE COMMON

SENSE!

CAUTION

To verify interlock switch function:

1. Park machine on a level surface, lower the cuttingunits, stop the engine and engage the parking brake.

2. Open control panel cover. Locate wire harness andconnectors near controller. Carefully unplug loop backconnector from harness connector (Fig. 27).

Figure 271. Wire Harness and Connectors

1

3. Connect the Diagnostic ACE display connector

(Fig. 28) to the harness connector. Make sure correctoverlay decal is positioned on Diagnostic ACE display.

4. Turn the key switch to the ON position, but do notstart machine.

Figure 281. Diagnostic ACE

Note: The red text on the overlay decal refers to inputswitches and the green text refers to outputs.

5. The �inputs displayed" LED, on lower right column

of the Diagnostic ACE, should be illuminated. If�outputs displayed" LED is illuminated, press thetoggle button, on Diagnostic ACE, to change LED to�inputs displayed".

6. The Diagnostic ACE will illuminate the LEDassociated with each of the inputs when that inputswitch is closed.

Individually, change each of the switches from open toclosed (i.e., sit on seat, engage traction pedal, etc.),and note that the appropriate LED on Diagnostic ACEwill blink on and off when corresponding switch isclosed and opened. Repeat on each switch that it ispossible to be changed by hand.

7. If switch is closed and appropriate LED does notblink on and off, check all wiring and connections to

switch and/or check switches with an ohm meter.Replace any defective switches and repair anydefective wiring.

Now start engine and raise and lower each cutting unit.Note the appropriate LED on the Diagnostic ACE (i.e.LED is illuminated when cutting unit is lowered andLED is not illuminated when cutting unit is raised.

The Diagnostic ACE also has the ability to detect whichoutput solenoids or relays are turned on. This is a quickway to determine if a machine malfunction is electrical

or hydraulic.

To verify output function:

1. Park machine on a level surface, lower the cuttingunits, stop the engine and engage the parking brake.

2. Open control panel cover. Locate wire harness andconnectors near controller. Carefully unplug loopbackconnector from harness connector.

21

OPERATING INSTRUCTIONS3. Connect the Diagnostic ACE connector to theharness connector. Make sure correct overlay decal ispositioned on Diagnostic ACE.

4. Turn the key switch to the ON position, but do notstart machine.

Note: The red text on the overlay decal refers to inputswitches and the green text refers to outputs.

5. The �outputs displayed" LED, on lower rightcolumn of Diagnostic ACE, should be illuminated. If�inputs displayed" LED is illuminated, press the togglebutton, on Diagnostic ACE, to change LED to �outputs

displayed".

Note: It may be necessary to toggle between �inputsdisplayed" and �outputs displayed" several times to dothe following step. To toggle back and forth, presstoggle button once. This may be done as often asrequired. DO NOT HOLD BUTTON.

6. Sit on the seat and attempt to operate the desiredfunction of the machine. (If you need help verifying thecorrect input settings for each function, refer to theLogic Chart on page 22) The appropriate output LED'sshould illuminate to indicate that the ECU is turning on

that function. (Refer to the logic chart to be certain ofthe specified output LED's).

Note: If any output LED is blinking, this indicates anelectrical problem with that OUTPUT. Repair / replacedefective electrical parts immediately. To reset ablinking LED, turn the key switch �OFF", then back

�ON".

If no output LED's are blinking, but the correct outputLED's do not illuminate, verify that all the input switcheswork by following the instructions on how to verifyinterlock switches. Verify correct switch function.

If the output LED's are on as specified, but the machinedoes not function properly, this indicates anon-electrical problem. Repair as necessary.

Note: Due to electrical system constraints, the outputLED's for �START", �MONITOR" and �ETR/ALT" maynot blink even though an electrical problem may existfor those functions. If the machine problem appears tobe with one of these functions, be certain to check the

electrical circuit with a volt / ohm meter to verify that noelectrical problem exists to these functions.

If electronic controller experiences an output failure foreither the cruise control or one of the cutting units, thecontroller will disable the machine function.Indications that this is the cause of the probleminclude:

A. Flashing green diagnostic light.

B. Diagnostic ACE will illuminate the �output fail"LED.

C. Diagnostic ACE will flash which output failed.

D. Machine will not respond to ignition key inputs.

The above indicates an ECU problem, contact your

local Authorized TORO Distributor for assistance.

If each output switch is in the correct position andfunctioning correctly, but the output LED's are notcorrectly illuminated, this indicates an ECU problem. Ifthis occurs, contact your Toro Distributor forassistance.

IMPORTANT: The Diagnostic ACE display should

not be left connected to the machine. It is not

designed to withstand the environment of the

machine's every day use. When done using

Diagnostic ACE, disconnect it from the machine

and reconnect loopback connector to harness

connector. Machine will not operate without

loopback connector installed on harness. Store

Diagnostic ACE in dry, secure location in shop, not

on machine.

OPERATING INSTRUCTIONSCHECK WARNING INDICATOR LIGHTS

Each day, before operating assure all warning lightsare functioning:

1. Sit on seat and apply parking brake. Turn ignitionkey ON and push TEST button. All lights shouldilluminate.

2. If a light fails to illuminate, replace the bulb and testagain.

PUSHING OR TOWING MACHINE

In an emergency, the Groundsmaster 580-D can bemoved by the following methods:

A. Actuate the by-pass valve in the variabledisplacement hydraulic pump and push or tow themachine.

B. Unlock the front hubs and tow the machine.

DANGER

There is no effective braking of the

Groundsmaster 580-D with the wheel

hubs disengaged. Unless it is on a level

surface or the wheels are blocked, the

machine will move freely. Do not unlock

the wheel hubs without either blocking the

wheels or connecting the machine to a

towing vehicle by means of a rigid towing

device.

Pump By-pass Method (short distances only)

IMPORTANT: Do not push or tow the machine faster

than 2-3 mph (3-4.8 km/hr) because internal

transmission damage may occur. The by-pass

valve must be open whenever the machine is

pushed or towed by this method, TORO does not

recommend this process be used as standard

procedure.

1. By-pass valve is located in left side of variabledisplacement pump (Fig. 29). Rotate the valve 1/2 to 1turn counter-clockwise to open and allow oil toby-pass internally. Because fluid is by-passed, themachine can be moved - slowly - without damagingthe transmission.

2. Rotate the valve clockwise until it is securely

seated before starting the engine. However, do notexceed 5-8 ft-lb (7-11 N m) torque to close the valve.

IMPORTANT: Running the engine with the by-pass

valve open will cause the transmission to overheat.

Figure 291. By-Pass Valve

Unlocked Hub Method

1. Either block the wheels or connect the machine toa towing vehicle with a rigid towing device.

Vehicle will roll with front wheel hubs

disengaged. Vehicle must be on a level

surface or wheels must be blocked. There

is no effective braking with wheel hubs

disengaged.

DANGER

2. Remove bolts securing the disengage covers toboth front wheel hubs.

3. Face the dimpled portion of the disengaged covers

inward and reinstall the covers. Wheel hubs are nowunlocked.

4. Lock the wheel hubs immediately after towingoperations are completed. Remove disengage coversand reinstall with the dimpled portion facing away fromthe wheel hubs.

CAUTION

Do not remove wheel blocks or towing

devices until wheel hubs are securely

locked.

OPERATING CHARACTERISTICS

Familiarization - Before mowing for the first time,

practice operating in a large, open and relatively levelarea. Start and stop the engine, operate in forward andreverse in LOW RANGE ground speed. Practice usingthe cruise control. Lower and raise cutting unitsindividually and simultaneously. When thoroughlyfamiliar with machine functions, practice operating

around trees and obstacles while using the individualwheel brakes. Also operate up and down slopes (INLOW RANGE).

24

OPERATING INSTRUCTIONSNote: TORO recommends HIGH RANGE groundspeed be used for road travel only (with cutting unitsup).

Points to consider while operating the traction unit,

cutting units or other implements are the hydrostatictransmission, engine speed, load on the cutting bladesor other implement components and the importance ofthe brakes. To maintain adequate power for thetraction unit and implement components whileoperating, regulate traction pedal position to keep

engine rpm high and relatively constant. Good rules tofollow are; decrease ground speed as the implementload increases, and increase ground speed as the loaddecreases.

Warning Systems - If a warning light and audiblewarning come on during operation, stop immediatelyand correct the problem before continuing. Seriousdamage could occur if the machine is operated with anuncorrected problem. However, if the engine stops

because of overheating, the emergency over-ridebutton can be used to operate the engine for shortintervals (Fig. 30).

Mowing - When approaching area to mow, positionthe ground speed selector in LOW RANGE and

release. Switch lever will return to neutral and HighRange light will go out. Move the throttle lever to FASTand lower the cutting units. Pull the sleeve of the deckdrive PTO switch up, position it in ENGAGE positionand release. Lever will return to neutral position and

PTO will be engaged automatically. Depress tractionpedal slowly to begin cutting operation.

Note: After lowering mowers, do not allow levers tosnap back to neutral. This could allow the levers to go

past neutral, lock the cutting units in a non-float modeand prevent them from following turf contours.

Should either outboard cutting unit contact animmovable object while mowing, the mower lift armlatch assembly absorbs the impact and breaks away.

This allows the cutting unit to swing rearward. Shouldthis occur, stop the machine. Fully raise the cuttingunit, then lower it to cutting position. This will allow thelift arm latch assembly to return to normal

configuration. Be sure to inspect the cutting unit fordamage and repair as necessary before resumingoperation.

Caution: This product may exceed noise levels of 85

dB(A) at the operator position. Ear protectors arerecommended for prolonged exposure to reduce thepotential of permanent hearing damage.

The individual wheel brakes can be used to assist in

turning the machine. However, use them carefully,especially on soft or wet turf because it may be tornaccidentally. The brakes are also beneficial to maintaintraction; for example, in some slope conditions, theuphill wheel may slip and lose traction. If this occurs,gradually depress the uphill brake pedal until the uphill

wheel stops slipping, thus increasing traction on thedownhill wheel.

To stop mowing, depress the brake pedal to stop anddisengage the cruise control (if used), move the PTO

switch to DISENGAGE and release (switch returns toneutral), then fully raise the cutting units.

High Range Ground Speed Operation - Tororecommends HIGH RANGE ground speed operation

be performed only on roads with the cutting units infully raised position. Start the machine in LOW RANGE,then shift to HIGH RANGE. The HIGH RANGE Indicatorlight will turn ON, indicating the machine is in the HIGHRANGE mode. To cease HIGH RANGE operation, take

foot off traction pedal and apply the brakes. Movethrottle lever to SLOW and position ground speedselector in LOW RANGE. If the engine begins to laborwhile climbing an incline, ease off on the traction pedaland shift to LOW RANGE. This will prevent overload ofthe engine and hydraulic system.

CAUTIONUse extreme care while operating in HIGH

RANGE ground speed selection. Watch

closely for bystanders, other vehicles and

possible hidden hazards and be prepared

to stop quickly.

Cruise Control Operation-While operating themachine at the desired ground speed, turn the cruisecontrol switch to ON and press the cruise control

actuating button. The traction pedal will be held in itsposition and a constant ground speed will bemaintained. A light on the steering column indicatesthe cruise control is in operation. Ground speed can bechanged by over-riding the traction pedal. The pedalwill maintain its new position when the over-riding

force is released.

To stop cruise control operation: Turn cruise controlswitch to OFF position or depress the service brake.

25

OPERATING INSTRUCTIONSNote: Hold the traction pedal in position whenstopping cruise control operation, otherwise themachine will stop abruptly due to hydrostatic brakingaction.

If it is an emergency and it becomes necessary to stop

suddenly while in cruise control, depress the servicebrake pedal, this breaks the electrical circuit, returnsthe traction pedal to neutral and stops the machine.

Stopping the Machine - To stop the machine andcease operation, take foot off traction pedal and applythe brakes. Move the throttle lever to SLOW, groundspeed selector to LOW RANGE and deck lift controls toneutral. Switch cruise control to OFF, set the parking

brake and turn ignition key to OFF. Remove the key ifthe machine is to be left unattended.

2. Torque lug nuts for rear wheels to 30-35 ft-lb(41-47 N m).

Check Tire Pressure

Since the Groundsmaster 580-D can be operated

under many different types of turf conditions, propertire pressure is very important. Check tire conditionand pressure daily and use the following guide tomaintain maximum turf conditions:

Under Normal mowing conditions and when usedon a wide variety of turf grasses - 15 psi

(103.4 kPa) front; 13 psi (89.6 kPa) rear. 50 psi(344.7 kPa) Casters.

When turf is wet and softer than normal - use lowtire pressure: 12 psi (82.7 kPa) front and 9 psi(62 kPa) rear.

When turf is dry and harder than normal, use highpressure: 18 psi (124 kPa) front and rear.

IMPORTANT: Do not operate in HIGH RANGE for

extended periods when tire pressure is less than 20

psi (138 kPa) because tires may be damaged. When

tire pressure exceeds 20 psi (138 kPa), HIGH

RANGE may be used.

INSPECTING AND SHARPENING BLADE

1. Raise cutting units to transport position, engageparking brake, shut engine off and remove key fromignition switch.

2. Carefully examine cutting ends of the blade,especially where the flat and sail (curved part) meet(Fig. 61A). Since sand and abrasive material can wearthe metal connecting the flat and sail portions, checkthe blade before using the machine. If any wear isnoticed (Fig. 61B), replace the blade: refer to

Removing Cutting Unit Blade above.

Figure 61

MAINTENANCE

CAUTION

If the blade is allowed to wear, a slot will

form between the sail and flat part of the

blade (Fig. 61C)). Part of the blade may

eventually break off and be thrown from

under the housing, possibly resulting in

serious injury to yourself or bystanders.

3. Examine cutting edges of all blades. Sharpencutting edges that are dull or nicked. To assuresharpness, sharpen only the top side of the cuttingedge while maintaining the original cutting angle(Fig. 62). If the same amount of metal is removed fromboth cutting edges, the blade will remain balanced.

Figure 62

SHARPEN AT THISANGLE ONLY

END VIEW

4. To check blade for being straight and parallel,remove from cutting unit. Lay blade on level surface

and check its ends. Blade ends must be slightly lowerthan blade center and cutting edge lower than heel ofthe blade. If so, it will produce good quality-of-cutand require minimal engine power to turn. By contrast,a blade with ends higher than blade center, or with

cutting edge higher than the blade heel, is warped orbent and must be replaced.

5. When re-assembling, make sure blade sail isfacing up. Torque the blade bolt to 140-165 ft-lb.

INSPECTING AND ADJUSTING CUTTINGUNIT BELT TENSION

IMPORTANT: After first ten hours of operation, checknew belts for proper tension; thereafter, check tensionevery 50 hours.

Front Cutting Unit -

Note: Belts for wing unit spindles are tensioned byspring loaded idlers and normally do not require

tensioning.

1. Position machine on level surface, lower cuttingunit to shop floor, engage parking brake, shut engineoff and remove key from ignition switch.

2. Remove deck covers.

Figure 691. High Range Height-of-Cut2. Move to Underside of Castor Arm3. Castor Arm

3. Rotate blade so ends face fore and aft. Measurefrom flat surface to front tip of cutting blade and recorddimension. Rotate same blade so opposite end faces

forward and repeat measurement. Difference betweenthe two measurements must not exceed 1/8 in. (3 mm).If difference exceeds 1/8 in. (3 mm), the blade is bent.Replace it. Use same procedures to measure allblades.

4. Rotate blade so ends face fore and aft. Measure

from flat surface to front of cutting blade and recorddimension. Repeat process with all blades andcompare measurements. Maximum difference allowedbetween any two adjacent blades is 1/4 in. (6 mm).Maximum difference allowed between the highest and

lowest blade measurement is 3/8 in. (10 mm). Ifmeasurements do not fit recommended standards,add shims between the cutting deck and spindlehousing; proceed to step 6. If measurements meetstandards, proceed to step 5.

5. Rotate blades so tips line up with one another. Tips

of adjacent blades must be within 1/8 in.(3 mm) of eachother. If tips are not within 1/8 in. (3 mm) of one another,add shims between spindle housing and bottom ofcutter deck; proceed to step 6.

6. Remove locknuts securing spindle housing to

deck in area where shims are to be added. To lower ablade, add a shim (Part No. 3256-24), to eachmounting bolt, between spindle housing and cutterdeck. Repeat step 5. Continue process until blade tipsare within the required dimensions.

IMPORTANT: Do not exceed three shims at any onehole location. If more than one shim is added to anyone hole location, install decreased amounts of shimsin adjacent holes.
