exposure to uncomfortable or loud noises can cause impairment or loss of hearing. Do not wear radios or music headphones while operating the machinery. Safe operation requires your full attention.
Never put hands or feet under any part of the machine while it is running. Except when changing or checking belt, always keep belt covers on mower for safety as well as
cleanliness.
Stop the e ngine before removing the grass catcher or unclogg ing the discharge chute. Never clear the
discharge chute with the engine running. Turn off the engine and be sure the blades have stopped before cleaning. Use a stick to clear a plugged discharge area. Never use your hand!
Exercise caution when loading or unloading the machine onto a trailer or truck. Always wear safety goggles or safety glasses with side shields when operating the mower . Never leave machine unattended with ignition key in switch, especially with children present. Be alert and turn the machine off if children enter the area. Always wear adequate eye protection when servicing the battery, hydraulic system, cooling system or
when grinding mower blades and removing accumulated debris.
Use extra caution when handling gasoline and other fuels. They are flammable and vapors are
explosive.
Never refuel tractor while engine is running; never refuel near an open flame or near devices which
can create a spark. Refuel outdoors preferably, or in well ventilated areas.
Never attempt to start engine when there is a strong odor of gasoline fumes present. Locate and
correct cause.
Never run the engine in an enclosed area unless exhaust is vented to the outside. Exhaust gases
contain carbon monoxide which is odorless and deadly poison.
Never attempt to make any adjustments or repairs to the tractor drive system, mower deck or any
attachment while the tractor engine is running or deck clutch is engaged. Repairs or maintenance requiring engine power should be performed by traine d personnel only.
Never work under the machine or attachment unless it is safely supported with jack stands. Make
certain machine is secure when it is raised and placed on the jack stands. The jack st a nds should not allow the machine to move when the engine is running and the drive wheels are rotating. Use only certified jack stands. Use only appropriate jack 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.
Before working on or under the deck, make cert ain engine cannot b e accidenta lly started. Shut eng ine
off and remove ignition switch key for maximum safety. Repairs or maintenance requiring engine power should be performed by trained personnel only.
Use a stick or similar instrument to clean under the mower making sure that no part of the body,
especially arms and hands are under mower.
Exercise caution when working under the deck as the mower blades are extremely sharp. Wearing
gloves or wrapping the blade(s) is advisable when working around or with the blades.
Do not touch hot parts of machine. Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good condition. Never tamper with safety devices. Check their proper operation regularly. Grass collection system components are subject to wear, damage and deterioration, which could

Using a ramp
Use extreme caution when loading and unloading a unit with a ramp. Use only a single, full width ramp; do not use individual ramps for each side of the unit. Having a full
width ramp provides a surface for the tractor frame to contact if the unit starts to tip backwards. It also reduces the risk of a wheel going off and the machine tipping over.
Do not exceed a 15 degree angle between the ramp and the ground or between the ramp and the
trailer or truck.
When on a ramp avoid sudden acceleration
Safety and Instruction Decals
Specific safety warning decals are located on the equipment near the immediate areas of potential
hazards. These decals should not be removed or obliterated. Replace them if they become non­readable.

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 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 hydraulic reservoir 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 in the full up position, using jack stands or blocks, 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 service center when assistance is needed.
TORQUE VALUES
WARNING: Particular attention must be given to tightening the drive wheel lug nuts, wheel motor nuts
and blade spindle bolts. Failure to correctly torque these items may result in the loss of a wheel or blade, which can cause serious damage or personal injury.
Torque values are given below:
Ft-lbs. Nm
Wheel (lug) nuts.................................65-75...........88.14-101.7
Wheel motor nut...............................290-310.........393.2-420.4
Blade spindle bolt top.........................65-75...........88.14-101.7
Blade spindle bolt bottom.....................118.................160.01
It is recommended that these be checked after the first 2 hours of operation initially, every 50 hours, and following removal for repair or replacement.
For all other torques refer to the various tractor parts manuals for standard torque charts.
NOTE: For engine torque values, see engine owner’s manual.
TIRES
It is important for level mowing that the tires have the same amount of air pressure. The recommended pressures are:
Drive wheels........................... 8-12 psi (55-69 KPa)
Gauge wheels............................semi-pneumatic
The bar tread tires are reversed from what is considered the normal operating position. this allows for bet­ter traction when backing up a slope.
108604 10/08 12-9
Solid fill tires are not recommended for Hustler turf equipment. On any machine, with solid filled tires,
HOUR METER
the warranty claim will be denied.
WARNING: Explosive separation of a tire and rim can cause serious injury or death. Do not attempt to mount a tire without the proper equipment and experience to perform the task. Always maintain the correct tire pressure and never over inflate. Never weld or heat a wheel and tire assembly as an explosion may occur. Welding can weaken or
deform a wheel. When inflating tires, stand to one side and not in front of or over the tire assembly. Check tires for low pressure, blemishes, damaged rims or missing lug bolts and nuts.
HOUR METER
To recognize when your machine needs servicing, check the hour meter and the maintenance schedule. The hour meter shows the number of hours the engine has run, and the maintenance schedule lists the service intervals. "FIG. 3"
.
FIG. 3
LUBRICATION
1. Grease the front gauge wheel bearings per the Maintenance Schedule. Use SAE multi-purpose grease.
2. Grease the four deck lift pivots, located to the side of the operator’s footrest per the Mainten ance Schedule. Use SAE multi-purpose grease.
3. Grease the deck idler per the Maintenance Schedule. Use SAE multi-purpose grease.
4. Grease the pump idler per the Maintenance Schedule. Use SAE multi-purpose grease.
5. Grease the two deck pusher arm pivots per the Maintenance Schedule. Use SAE multi-purpose grease.
6. Grease the blade spindle assemblies per the Maintenance Schedule. The spindle assemblies require lubrication annually. Each spindle shaft is equipped with a grease zerk located under the deck. Use no more than one or two ounces of SAE multi-purpose grease, (1 to 2 pumps on an average grease gun). Do not force lubricant into grease zerks. Bearings are sealed and do not require much lubricant.
ELECTRICAL SYSTEM
The electrical system is a 12-volt, negative ground. Recommended battery size is a garden tractor BCI group U1R with 225 or better cranking AMP rating. A maintenance-free battery is recommended. Other­wise, follow battery manufacturer’s maintenance, safety, storing and charging specificat ions.
12-10 108604 10/08
The battery is located under the seat platform "FIG. 4".

FIG. 4
WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
WARNING: Avoid skin and clothing contact with battery acid. Always wear eye protection when checking the battery , acid can cause serious injury to skin and eyes.
If contact occurs, flush area with clean water and call physician immediately. Acid will also damage clothing.
Do not drink the battery electrolyte. Do not allow open flame near the battery when charging. Hydrogen gas forms inside the battery. This gas is both toxic and flammable and may cause an
explosion if exposed to flame. Always remove the negative ground first and replace it last. Do not overfill battery. Electrolyte may overflow and damage paint, wiring or structure. When cleaning the battery, use soap
and water. Be careful not to get soap and water into the battery. Clean the battery terminal s with a solution of four parts water and one part baking soda when they become corroded.
WARNING: Shorts caused by battery terminals or metal too ls touching m etal tractor compon ents can cause sparks. Sparks can cause a battery gas explosion which will result in personal injury.
Prevent the battery terminals from touching any metal tractor parts when removing or installing the battery.
Do not allow metal tools to short between the battery terminals and metal tractor parts.
WARNING: Incorr ect battery cable routing could cause dam age to the tractor and battery cables. This can cause sparks which can cause a battery gas explosion which will result in personal injury.
Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. Always connect the positive (red) battery cable before connecting the negative (black) cable.
Common circuit failures are usually caused by shorting, corroded or dirty terminals; loose connections, defective wire insulation or broken wires. Switches, solenoids and ignition components may also fail, causing a shorted or open circuit.
108604 10/08 12-11
Before attempting any failure diagnosis of the electrical system, use a test light or voltmeter to check the
SEAT PLATFORM CHECK
SEAT PLATFORM
CONTROL LEVER
battery voltage. If the battery voltage is satisfactory, check the cleanliness and tightness of the terminals and ground connections. A general understanding of electrical servicing and use of basic test equipment is necessary for troubleshooting and repair.
Major overhaul or repair of the starting motor or charging system should be performed by trained technicians only.
ACCESS TO ENGINE AND HYDRAULIC PUMPS
The hydraulic pumps are accessed by lifting the seat pla tfo rm. The seat platfor m is hinged at the front. To raise it, release seat latch and tilt seat platform up and forward.The seat platform catch ("FIG. 5") will prevent the seat from going all the way over. However, if more access is desired under the seat platform, the seat platform catch can be raised allowing the seat to pivot more. Make certain to place the control
arms in the park brake position and pivot the arm rests upward before placing the seat platform in the full forward position to prevent arm rest damage.
HYDRAULIC SYSTEM
Before applying pressure to hydraulic system, make sure all connections are tight and all hoses and lines are in good condition. To find a leak under pressure , use a pie ce of car dboar d or wo od — never use your hands. Relieve all pressure in the system before disconnecting or working on hydraulic lines. To relieve pressure, lower all attachments and shut off engine.
The 1.0 U.S. gallon (3.79 liter) hydraulic reservoir is lo cate d in front of the engine an d under the operator’s platform "FIG. 6".
Check oil level in hydraulic system after every 50 hours of operation or weekly, whichever occurs first. Check more often if system appears to be leaking or otherwise malfunctioning.
Fluid level should be 1” from top of reservoir. Use only SAE 10W40 SG, SF/CC, CD service motor oil. Change hydraulic system filter element ("FIG. 6") after first 50 hours of tr actor ope ratio n, then replace filter
and oil in reservoir every 500 hours thereafter. When changing hydraulic oil use 1/2 unit (approximately
3.5 oz.) of Lubrizol additive (Hustler P/N 027912). This additive, available from your Hustler dealer, will increase the performance life of the hydraulic system components.
FIG. 5
WARNING: Always wear adequate eye protection when servicing the hydraulic system and batt er y.
IMPORTANT: Never use hydraulic or automatic transmission fluid in this system; use only motor oil as
specified. Remember, dir t is the primary enemy of any hydraulic system. WARNING: Hydraulic oil escaping under pressure can penetrate skin. Hydraulic oil may cause infec-
tion in a minor cut or opening in the skin. If exposed to hydraulic fluid, see a doctor at once.

DANGER: Observe usual fuel handling precautio ns : Do not smoke while refueling. Do not fill tank with engine running or while engine is hot. Clean up any gasoline spills. Allow engine to cool before storing machine inside a building. Keep fuel away from open flame or spark and store machine away from open flame or spark if there is
fuel in the tank. Use extra caution when handling gasoline and other fuels. They are flammable and vapors are
explosive. A fire or explosion from gasoline can burn you and others and can damage property. Refuel outdoors preferably, or in well ventilated areas. Never attempt to start engine when there is a strong odor of gasoline fumes present. Locate and
correct cause. Store gaso line in an approved cont a iner and keep it out of th e reach of childre n. Never buy more tha n
a 30 day supply of gasoline. Always place gasoline containers on the ground away from your vehicle before filling. Do not fill gasoline containers inside a vehicle or on a truck or trailer as interior carpet s or plastic truck
bed liners may insulate the container and slow the loss of any static charge. When practical, remove equipment from the truck or trailer and refuel the eq uipment with its wheels o n
the ground. If this is not possible, then refuel the equipment on the truck or trailer using a portable container and not a gasoline dispenser no zzle. If a gasoline disp enser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

A specially designed dry filter is standard equipment on the Hustler ATZ tractors and supplies clean combustion air to the engine "FIG. 12".
RECOMMENDED SERVICE PROCEDURE
1. Overservicing the air filter element.
2. Improper installation.
3. Damaged filter, seals or canister.
4. Incorrect air filter element size.
5. Use of poorly designed aftermarket air filter elements.
FIG. 12
Many engine failures can be attributed to improper air cleaner servicing. Ingested dust and dirt will cause cylinder, piston and bearing damage in a few hours. “Dusted” engines will result from:
12-16 108604 10/08
Air cleaner servicing is an inexpensive maintenance check that can prevent costly non-warrantable premature engine damage.
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
Donaldson 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 an d a c tu ally 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.
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.
IMPROPER INSTALLATION OF AN AIR FILTER ELEMENT
Dust must not leak past the seals on each end of the air filter element. The filter must be aligned with in the canister and properly seated for an effective seal so that no dirt can enter the en gine.
DAMAGED FILTER, SEALS OR CANISTER
Never bang or bump the filter element against the tire or any solid object, as dust and dirt particles will be forced through the media causing continual passing of dirt into the engine. Visually inspect the outside of the air cleaner canister periodically for external damage and replace if necessary.
INCORRECT AIR CLEANER ELEMENT
Use only the correct Donaldson air filter element, Hustler part number 785261, which is designed to fit the canister properly.
Hustler air filter elements have the correct media composition, filter area, micron size and dimensions. Always use genuine Hustler filters. Many aftermarket filters have been found to be incompatible with Hustler’s canisters and engines.
The air filter must remain intact to block passage of dirt and foreign particles from entering the engine. Being inclined to disbelieve the need for more expen sive air filter elem ents used on gasoline engines may cause some individuals to opt for a less expensive part.
The filter element must be sufficient size and construc tion to withstand stresses, caused by rapid cycling of the air volume demanded by the engine, without cracking or tearing under fatigue and pressure (especially diesel engines). Therefore, Hustler T u rf Equipment and the engine man ufacturers ha ve carefully selected a reliable filter designed to fit the needs of the engines. The filter specified is a Donaldson filter, Hustler part number 785261.
108604 10/08 12-17
Owners should be reminded that failure to use original equipment replacement parts is an “alteration” and
INDICATOR
RESET BUTTON
will not be considered for warranty in the event of engine damage.
RECOMMENDED SERVICE PROCEDURE
1. Release clamps and remove element. Clean the canister with a damp cloth.
2. Before installing a new element, inspect it by placing a bright ligh t insid e an d rotate the elem en t slow ly, looking 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 clean er body, then tighten the clamps.
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. Lo cate and rep air th e source of ing ested dirt.
6. Never operate a machine without an air filter installed.
AIR RESTRICTION INDICATOR
Any unit with a Kohler or Kawasaki engine will have an air restriction indicator installed in the air cleaner "FIG. 13".
Replace the element whenever the restriction indicator shows 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 "FIG. 13" A restriction indicator takes the guesswork out of air cleaner servicing and allows you to safely benefit from
the filter’s optimum performance.
