GENERAL INFORMATION

Service Program

This manual is part of a service package for the Hustler ® X-

ONE i mowers. Use of this manual in conjunction with other

Hustler ® mower and component manuals will provide the information necessary to service and maintain Hustler ® X-ONE i mowers.

This General Service Manual is a service guide for use by

Service Technicians. It provides the necessary information needed to perform normal maintenance requirements on these units.

The Parts Manual provides a complete parts listing for the unit. Use this manual when ordering parts.

The Operator's Manual provides fundamental operational information and operational safety that is needed when operating the mower.

The component manuals are furnished by the various manufacturers to be used for the troubleshooting and servicing of their products.

Maintenance Introduction

Regular maintenance is the best prevention for costly downtime or expensive, premature repair. The following pages contain suggested maintenance information and schedules which the operator/mechanic should follow on a routine basis.

Remain alert for unusual noises, they could be signaling a problem. Visually inspect the machine for any abnormal wear or damage. A good time to detect potential problems is while performing scheduled maintenance service. Correcting the problem as quickly as possible is the best insurance.

Clear away heavy build-up of grease, oil and dirt, especially in the engine and under the seat platform areas; minute dust particles are abrasive to close-tolerance engine and hydraulic assemblies.

Daily inspect mower for grass clippings and wire and string tangles. The underside of the mower deck will collect a build-up of grass clippings and dirt, especially when grass is wet or has high moisture content. This build-up will harden, restricting blade and air movement and will probably show a poorer quality of cutting. Therefore it should be removed routinely.

To do this it will be necessary to raise and block the deck, using jack stands or blocks, in the full up position and scrape the build-up from underneath.

Some repairs require the assistance of a trained service mechanic and should not be attempted by unskilled personnel.

Consult your Hustler ® Turf Equipment service center when assistance is needed.

Information included in this manual was current at the time of printing, but subsequent production changes may cause your machine to vary slightly in detail. Hustler ® Turf Equipment reserves the right to redesign and change the machine as deemed necessary, without notification. If a change has been made to your machine which is not reflected in this service manual contact the Customer Service Department at Hustler ® Turf

Equipment for additional information.

Warranty

Warranty repair must be performed by a Hustler ® Turf

Equipment Authorized Dealer before warranty credit can be allowed. Work performed by anyone other than an Authorized

Dealer will invalidate the warranty claim and warranty credit will not be approved.

Steering Adjustments

Steering control lever neutral adjustment

The mower’s steering has been factory adjusted to eliminate creeping when the steering control levers are in the neutral position. However, should the mower begin to creep, the steering control lever linkage can be adjusted.

Before considering any adjustment, check the tire air pressure.

Unequal tire pressure will cause the mower to drift to one side.

Refer to tire pressure information in the Tires section for detailed information.

NOTE: Proper park brake adjustment must be completed before the steering control lever neutral adjustment can be done.

Refer to the Park Brake Spring Adjustment section for detailed information.

Fine adjustment to the unit’s steering is made with the transmission’s control rod.

Neutral is properly adjusted when the steering control levers are in the park brake position and the transmissions do not

“whine”.

If this occurs, the steering control linkage may be adjusted as follows:

WARNING

This procedure will require that the unit be raised and blocked up off of the ground. It is necessary for the wheels to rotate without coming in contact with the floor or any object that would permit the unit to propel itself.

Stay clear and exercise caution when rotating wheels to prevent injury. Use only appropriate vehicle stands, with a minimum weight rating of 2000 pounds to block the unit up. Use in pairs only. Follow the instructions supplied with the vehicle stands.

WARNING

Keep hands, hair, clothing, etc., clear of the cooling fans on top of the transmissions. Exercise extreme caution.

WARNING

POWER UNIT MAINTENANCE

Untrained maintenance personnel should never attempt to make any adjustments or repairs to the mower’s drive system while the engine is running. The following proce- dures should be performed by trained maintenance personnel only.

NOTE: Before adjustment, make certain hydraulic system oil is at operating temperature.

1.

Raise the rear of the mower and block with certified jack stands. The rear wheels need to be able to rotate freely and clear of all obstructions.

2.

Chock the front tires.

3.

Raise the seat platform and disconnect the mower harness from the seat switch. Bypass the seat switch by connecting the two mower harness female spades

together. Figure 5-1

Female spades

6.

If wheel(s) are rotating forward, loosen the jam nuts on the pump linkage rods and rotate the rod to lengthen the steering control linkage until the wheel(s) come to a stop.

Figure 5-3

7.

Repeat for the opposite side if necessary.

8.

If wheel(s) are rotating in reverse then loosen the jam nuts on the pump linkage rods and rotate the rod to shorten the steering control linkage until the wheel(s)

come to a stop. Figure 5-3

Repeat for the opposite side if necessary

9.

When both wheels remain in neutral, tighten the jam nuts to lock the turnbuckle in place.

10.

Test again by moving the steering control levers forward and backward before returning them to the neutral position. If the tires are in neutral, the unit is now ready for operation.

11.

After adjusting for neutral it may be necessary to readjust the control lever stop and/or damper.

12.

IMPORTANT: With the engine off, disconnect the two female spade connectors from each other (from step #3) and reconnect them to the seat switch. This must be completed so that the safety circuit is functioning

WARNING

Never operate the mower with a non-functioning seat switch. Always reconnect the seat switch to the mower harness.

13.

Check to make sure all tools or obstructions are removed from under the mower.

14.

Raise the rear of the mower and remove the jack stands.

Lower the mower.

15.

Lower and secure the seat platform.

Control lever stops

The internal steering control lever stops (see Figure 5-4) are

designed to keep the pumps from bottoming out internally. The

external steering control lever stops (Figure 5-5) may be

adjusted to help the mower drive straight when the steering control levers are pushed forward against the stops.

To keep the pumps from bottoming out internally use the following procedure:

This adjustment is only required if the hydraulic pump(s) have been replaced.

WARNING

properly. Figure 5-1

WARNING

Do not operate the mower without plugging the mower’s wiring harness into the seat switch. This switch is an important part of the safety start interlock system. Serious injury can result if the seat switch is not plugged into the mower’s wiring harness.

REV A 5-2

Pump damage will occur if these stops are set incorrectly.

1.

To make the first adjustment the mower engine must not be running.

2.

Check to make sure the steering control levers are against the stops before the pumps are bottomed out internally.

3.

To do this, gently and slowly move the steering control levers forward and feel if there is some resistance on the pump lever before the control levers hit the stops. Check one side at a time. If you sense that the pump arms are stopping the forward motion of the control arms, loosen the jam nut on the adjustable stop of the corresponding side, turn the stop (set screw) inward to stop the steering control levers slightly before the pump bottoms out. Lock in place when the adjustment is correct by re-tightening the jam nut. Do this for each side.

To adjust the stops for driving straight when steering control levers are against the stops during operation:

1.

Determine which drive tire is rotating too fast when both steering control levers are against the stops in the control

panel (see Figure 5-5).

2.

Then, stop the mower and loosen the lock nut on the side which is rotating too fast and turn the stop (set screw) inward to stop the steering control lever sooner. Tighten the lock nut on the stop and test again.

3.

Repeat this procedure until unit drives straight.

NOTE: Since this is a hydrostatic drive, variables such as temperature of oil, efficiency of pumps and motors, tire pressure etc. may effect the consistency of the ability to rely on the stops to drive straight without the operator making minor steering adjustments with the control arms.

6.

Tighten the nut on the steering damper’s front ball stud.

NOTE: The damper must not bottom out when the pump lever is fully stroked in either direction.

7.

Reconnect the negative battery cable.

8.

Lower and secure the seat platform.

9.

To check, move the steering control lever to the reverse position and release. The steering control lever should return to the neutral position. If not, repeat steps 1 through 6.

Inspect belts frequently for wear and serviceability. Replace a belt that shows signs of severe cuts, tears, separation, weather checking and cracking, or burns caused by slipping. Slight raveling of belt covering does not indicate failure, trim ravelings with a sharp knife.

Inspect the belt pulley grooves and flanges for wear. A new belt, or one in good condition, should never run against the bottom of the groove. Replace the pulley when this is the case, otherwise belt will lose power and slip excessively.

Never pry a belt to get it on a pulley as this will cut or damage the fibers of the belt covering.

Keep oil and grease away from belts, and never use belt dressings. Any of these will destroy the belt composition in a very short time.

Rotate the tire. If the brake is adjusted properly the tire will still rotate but friction will start to become noticeable here. However, if no brake resistance is noticed, the brake needs adjusted as follows:

a. Loosen the brake linkage jam nuts. (Figure 5-13)

Rotate the tire and at the same time rotate the turnbuckle to shorten the length of the brake linkage to increase the brake pressure. When you feel the brake begin to engage, stop adjusting the turnbuckle.

Re-tighten the jam nuts on the turnbuckle.

b. Place the steering control lever in the park brake slot.

The tire should not rotate when the control lever is in

the park brake position. Figure 5-12

c. Place the control lever in the neutral position. The tire should rotate freely.

The transmission drive belt tension remains constant by means of a tension idler and spring. The spring tension should be such that the belt does not slip under normal operating load conditions, assuming the belt is not excessively worn or damaged. As the belt stretches and wears in, adjustment may become necessary.

The proper belt tension is achieved when the tension spring is stretched to a dimension of 8.0” – 8.5” (20.3 – 21.6cm) when measured from the inside of the hook to the inside of the other

hook. Figure 5-14

To increase belt tension, remove the spring hook from the idler spring mount. Unbolt the idler spring mount from the mower frame and move it to a set of holes in the frame that allow for the spring to be extended to the proper extension.

Attach the mount and then re-attach the spring hook to it. Figure

ENGINE MAINTENANCE

General Engine Maintenance

Detailed instructions and recommendations for break-in and regular maintenance are specified in the Engine Owner’s manual. Please refer to this manual for engine servicing, lubricating oil levels with quality and viscosity recommendations, bolt torques, etc. The engine warranty is backed by the engine manufacturer.

Engine Oil and Filter

IMPORTANT: All oil drips or spills must be cleaned off of the exhaust system before operating the machine.

WARNING

If the engine has been running and is up to operating temperature, allow the engine to cool before changing the oil.

Engine and engine oil will be very hot, so be very careful when changing oil and wear the appropriate protective gear to avoid being burned or exposed to engine oil.

Check engine oil daily and after every 4 hours of operation.

Machine must be setting level when checking oil. Refer to engine manual and maintenance schedule for oil recommendation and capacities.

IMPORTANT: Change the engine oil and filter after the first 5 hours of operation and per the engine manufacturer’s recommendations after that. If mower is being operated in extremely dirty conditions, then it is recommended oil be changed more frequently.

IMPORTANT: When removing the oil filter take precautions to minimize oil spillage on the exhaust system.

Draining the engine oil:

1.

Locate the oil drain valve on the engine. Figure 6-1,

2.

Position a suitable oil drain container under the machine below the oil drain valve.

3.

Twist the valve counterclockwise to open the valve.

Allow 10 minutes for engine oil to adequately drain.

4.

After oil is drained, close the valve by twisting it clockwise.

5.

Clean up any spilled oil.

Of course, at some point the filter media becomes too clogged to allow air to pass.

The mowing conditions will determine the frequency of air filter element changing.

These units have an air restriction indicator installed in the air cleaner. Figure 6-4

Replace the element whenever the restriction indicator reaches the change filter red line. Check the indicator daily and replace element as needed or annually whichever occurs first.

Reset the indicator by pushing in on the yellow button after each element change. Figure 6-4

Reset button

Figure 6-3 for any holes or tears in the paper. Also check gaskets for cuts or tears. Do not attempt to use a damaged element which will allow abrasive particles to enter the engine.

3.

Reinstall the dust cup. Make sure it seals all the way around the air cleaner body, then tighten the clamps.

Figure 6-2

4.

Check all fittings and clamps periodically for tightness and inspect hoses for holes or cracks.

5.

Periodically check the intake hose for signs of ingested dust. Locate and repair the source of ingested dirt.

6.

Never operate a machine without an air filter installed.

Overservicing

Overservicing occurs when an air filter element is removed for cleaning or replacement before it is necessary. Each time the filter is removed a small amount of dirt and dust could fall in the intake system. This accumulated dirt can cause a dusted engine.

It only takes a few grams of ingested dirt over the normal service life of an engine to cause a dusted engine.

Do not clean element, replace with a new element only.

Cleaning used air filter elements, through improper cleaning procedures, can get dust on the inside of the filter causing dirt ingestion and engine failure.

It is important to note that whenever an air filter element is cleaned by any method, the person or company performing the cleaning assumes responsibility for the integrity of the filter from then on. The warranty for air filters expires upon cleaning or servicing in any manner because the condition of the filter after servicing is completely out of their control.

Therefore, on a dust ingested engine failure, there will be no warranty consideration if the air filter element has been cleaned or serviced in any manner.

A partially dirty air filter element works better than a new element. Therefore, a dirty filter element is not bad for the engine unless it is excessively restricting the air flow and engine performance is affected. The reason is simple. The media in the filter must be porous to allow air to pass through it. When dirty air passes through the filter, the dirt plugs some of the holes in the media and actually acts as part of the filter media. When the next round of dirt enters, the first dirt helps filter out even smaller particles making the filter more efficient at stopping dirt from entering the engine. This is referred to as barrier filtration.

Mower blade maintenance

Check the mower blades daily, they are the key to power efficiency and well groomed turf. Keep them sharp, a dull blade will tear rather than cut the grass, leaving a brown ragged top on the grass within a few hours. A dull blade also requires more power from the engine.

117604

Replace any blade which is bent, cracked or broken.

WARNING

Never attempt to straighten a bent blade by heating, or weld a cracked or broken blade as the blade may break and cause serious injury. Replace worn or damaged blades.

WARNING

Never work with blades while engine is running or deck clutch switch is engaged (on). Always place deck clutch switch in the disengaged position, place steering control levers in the park brake position and turn engine off and disconnect negative battery cable. Block up mower when you must work under it. Wear gloves when handling blades. Always check for blade damage if mower strikes rock, branch or other foreign object during mowing!

WARNING

Always wear adequate eye protection when grinding mower blades.

Mower blade removal

Use a 15/16” wrench to remove the 5/8” cap screw holding the blade to the spindle shaft from underneath. NOTE: A blade holding tool (part number 381442) is available from Hustler

®

Turf Equipment. It is designed to prevent the blades from rotating when they are being removed or installed on the spindle. Contact your Hustler

®

dealer for more information.

Sharpen the blades on a grinder following pattern as shown

(Figure 7-8). Touch-up sharpening can be done with a file

Check the blades for balance following grinding. A commercial balancing tool is available through most hardware supply stores, or balancing can be done by placing the blade on an inverted line punch or 5/8” bolt. Blade should not lean or tilt.

Spin the blade slowly, blade should not wobble. If blade is out of balance, true it up before reinstalling.

Lay the blade on a flat surface and check for distortion

(Figure 7-9 & Figure 7-10). Replace any distorted blade.

Do not re-use spindle bolts which have stripped, worn or undercut threads. Torque bolts on spindles to 118 foot-pounds

(160.0 Nm) when reinstalling blades.

Properly compressed cup washers maintain the correct compression load on the blades. Replace the cup washers if they are cracked or flattened.

IMPORTANT: The blade sail (curved part) must be pointing upward toward the inside of the deck to ensure proper cutting.

IMPORTANT: When mounting blades, rotate them after installation to ensure blade tips do not touch each other or sides of the mower.

WARNING

Failure to correctly torque the bolt may result in the loss of the blade which can cause serious injury.

WARNING

Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves and use extra caution when servicing them.

Resharpening pattern

Do not sharpen to original pattern (below). It is easier to get a straight cutting edge following the resharpening pattern shown above.
