4-Wheel Drive  
Your Bush Hog Utility Vehicle is equipped with an exclusive 4-wheel  
drive system that can be activated by a switch on the dash board.  
When the switch is off, the vehicle is in two-wheel drive at all times.  
When the switch is in 4-wheel drive, the front wheels will automati-  
cally engage anytime the rear wheels begin to lose traction. When  
the rear wheels regain traction, the front wheels will automatically dis-  
engage.  
The 4-wheel drive switch light indicates whether the vehicle is in 4-  
wheel drive. There is no limit to the length of time the vehicle may  
remain in 4-wheel drive.  
The 4-wheel drive switch may be turned on or off while the vehicle is  
moving. If the switch is turned off while the front hubs are driving, they  
will not release until the rear wheels regain traction.  
CAUTION  
SWITCHING TO 4-WHEEL DRIVE WHILE THE REAR  
WHEELS ARE SPINNING MAY CAUSE SEVERE DRIVE  
SHAFT AND CLUTCH DAMAGE. ALWAYS SWITCH TO 4-  
WHEEL DRIVE WHILE THE REAR WHEELS HAVE TRAC-  
TION OR ARE AT REST.  
Disengaging 4-Wheel Drive  
Under certain conditions, it may be possible for one or both hubs to  
remain engaged unnecessarily. This condition causes increased  
steering effort and some vehicle speed restriction.  
Take the following steps to disengage the 4-wheel drive system:  
1. Stop the vehicle.  
2. Shift to reverse and back up a minimum of 10 feet.

Engine Oil  
Maintain the engine oil at the proper level to ensure a properly func-  
tioning engine, and change the oil and oil filter every 100 hours or  
every six months, whichever comes first. Dirt and metal particles col-  
lect in the oil, and oil loses its lubricative quality if used too long.  
Suggested break-in oil change is at 25 hours, or one month,  
whichever comes first. Severe use operation requires more frequent  
service. Severe use includes continuous duty in dusty or wet condi-  
tions, and cold weather operation. NOTE: Severe use/cold weather  
operation is when all operating is at below 10°F and/or when operat-  
ing between 10°F and 30°F if most trips are slow speed and less  
than five miles. Always change the oil filter when changing oil.  
Oil Check  
The engine oil can be checked and/or refilled by folding the bottom  
seat cushion up and forward exposing the engine.  
1. Position the vehicle on a level surface.  
2. Start the engine and let it idle for 20 - 30 seconds.  
3. Stop the engine and fold the seat forward.  
4. Remove the dipstick and wipe it clean with a clean cloth.  
5. Replace the dipstick completely into the engine.  
6. Remove the dipstick and check to see that the oil level is  
between the full and add marks. Add oil if necessary. Do not over-  
fill.  
NOTE: A rising oil level between checks in cool weather driving can indi-  
cate moisture collecting in the crankcase. If the oil level is above the full  
mark, change the oil.

Constantly Variable Transmission (CVT)  
WARNING  
FAILURE TO COMPLY WITH THE INSTRUCTIONS IN THIS  
WARNING CAN RESULT IN SEVERE INJURY OR DEATH.  
Do not modify any component of the CVT system. Doing so may  
reduce its strength so that a failure may occur at a high speed. The  
CVT system has been precision balanced. Any modification will  
cause the system to be out of balance, creating vibration and addi-  
tional loads on components.  
The CVT system rotates at high speeds, creating large amounts of  
force on clutch components. Extensive engineering and testing has  
been conducted to ensure the safety of this product. However, as the  
owner, you have the following responsibilities to make sure this sys-  
tem remains safe:  
Always follow all recommended maintenance procedures. See your  
dealer if required.  
This CVT system is intended for use on the Bush Hog utility vehicle.  
Do not install it on any other product.  
Always make sure the CVT housing is securely in place during operation.  
CVT Drying  
There may be some instances when water is accidently ingested into the  
CVT system Use the following instructions to dry it out before operating.  
1. Shift the transmission into neutral and apply full throttle for no longer  
than 10 seconds and repeat as necessary. This will expel the mois-  
ture and air dry the belt and clutches.  
2. Allow the engine RPM to settle to idle speed, then shift the trans-  
mission to the lowest available range.  
3. Test for belt slippage. If the belt slips, repeat the process.

Fuel Filter  
Your Bush Hog utility vehicle is equipped with an in-line fuel filter that  
should be replaced by your dealer after every 100 hours of opera-  
tion.Do not attempt to clean the fuel filter.  
Spark Plugs  
The spark plugs should be changed every 100 hours. The spark plugs  
are accessible from under the seat or under the cargo box. Always use  
the spark plugs recommended by the engine manufacturer and set the  
gap as specified.  
WARNING  
A HOT EXHAUST SYSTEM AND ENGINE CAN CAUSE  
SERIOUS BURNS. WEAR PROTECTIVE GLOVES WHEN  
REMOVING A SPARK PLUG FOR INSPECTION.  
Spark plug condition is indicative of engine operation. The spark plug  
firing end condition should be read after the engine is warmed up and  
the vehicle is driven at higher speeds. Immediately check the spark  
plug for correct color.  
1. Normal  
The normal insulator tip is gray, tan, or light brown. There will be few  
combustion deposits. The electrodes are not burned or eroded. This  
indicates the proper type and heat range for the engine and service.  
NOTE: The tip should not be white. A white tip indicates overheating,  
caused by use of an improper spark plug or incorrect carburetion  
adjustments.  
2. Wet Fouled  
The wet fouled insulator tip is black. A damp oil film covers the firing  
end. There may be a carbon layer over the entire nose. Generally, the  
electrodes are not worn. General causes of fouling are excessive oil,  
use of non-recommended injection oil, improper use of the choke. or  
incorrect carburetion adjustments.  
Spark Plug Removal and Replacement  
1. Open the seat and/or the cargo box to access the engine compart-  
ment.  
2. Remove the spark plug boot and using a socket wrench, remove

Throttle Freeplay  
If the throttle pedal has excessive play due to cable stretch or cable  
misadjustment, it will cause a delay in throttle response, especially at  
low engine speed. The throttle may also not open fully. If the throttle  
pedal has no freeplay, the throttle may be hard to control, and idle  
may be erratic.  
Throttle Freeplay Inspection  
1. Apply parking brake.  
2. Shift the gear lever into neutral.  
3. Start the engine and warm it up thoroughly.  
4. Measure the distance the throttle pedal moves before the engine  
begins to pick up speed. Freeplay should be from 1/16” to 1/8”.  
Note: The throttle system is not intended to be adjusted by the owner.  
If problems occur, take the vehicle to your dealer for adjustments.

Brake Inspection  
The front and rear brakes are hydraulic disc type brakes and are acti-  
vated by the brake pedal.  
Routine inspections are recommended to keep the brake system in  
good operating condition. Inspect the level of the brake fluid before  
each operation.  
Change the brake fluid at the intervals outlined in the Maintenance  
Schedule beginning on page 49. The brake fluid should also be  
changed if it becomes contaminated, if the fluid level is below the min-  
imum, or if the type and brand of the fluid in the reservoir are  
unknown.  
Inspection Procedure  
1. Position the vehicle on level ground.  
2. Inspect the brake fluid by looking at the reservoir under the hood.  
The level should be between the upper (MAX) and lower (MIN)  
level lines.  
3. If the fluid level is lower than the lower level line, add brake fluid  
to the upper (MAX) line.  
4. Apply the brake forcefully for a few seconds and check for fluid  
`
leakage around the fittings.  
WARNING  
AFTER OPENING A BOTTLE OF BRAKE FLUID, ALWAYS DIS-  
CARD ANY UNUSED PORTION. NEVER STORE OR USE A  
PARTIAL BOTTLE. BRAKE FLUID IS HYGROSCOPIC, MEAN-  
ING IT RAPIDLY ABSORBS MOISTURE FROM THE AIR. THE  
MOISTURE CAUSES THE BOILING TEMPERATURE OF THE  
BRAKE FLUID TO DROP, WHICH CAN LEAD TO EARLY  
BRAKE FADE AND THE POSSIBILITY OF ACCIDENT OR  
SEVERE INJURY.

a dime.  
Parking Brake Adjustment  
1. Engage the parking brake by stepping on the foot lever (Trail  
Hand) or pulling up the hand lever (Trail Hunter). the vehicle  
should not roll while parked. If the vehicle moves, adjustment is  
needed.  
2. (Trail Hand) On the underside of the vehicle the threaded end of  
the parking brake cable passes through an equalizer bracket.  
Hex nuts on each side of the equalizer position the brake cable.  
Loosen the nut on the front side of the equalizer and then tighten  
the rear side nut to increase pressure on the brake system. Test  
the brake system and adjust again, if needed. When adjustment  
is satisfactory, tighten both nuts securely against the equalizer  
bracket.  
(Trail Hunter) The hand lever is equipped with a rotating knob to  
adjust the engagement of the parking brake. Loosen the set  
screw on the side of the knob and turn the knob clockwise to

Steering Wheel Inspection  
Check the steering wheel for freeplay and smooth operation as out-  
lined in the Maintenance Schedule.  
1. Park the vehicle on level ground.  
2. Lightly turn the steering wheel left and right.  
3. There should be 0.8 - 1.0 in. (20 25 mm) of freeplay.  
4. If there is excessive freeplay or strange noises, or the steering  
feels rough or “catchy”, have the steering system inspected by an  
authorized Bush Hog dealer.  
Seat Belts  
Inspect all seat belts for proper operation before each use of the vehicle.  
1. Push the latch plate into the buckle until it clicks. The latch plate  
must slide smoothly into the buckle. A click indicates that it is  
securely latched.  
2. Push the red button to make sure it releases freely.  
3. Check the belt for wear, cuts or damage. If any irregularities are  
found, have the seat belt system checked and/or replaced by an  
authorized dealer.  
The seat belt angles should be adjusted to suit the individual in that  
particular seat before driving. Make sure the seat belt angle is adjust-  
ed to the lowest possible lap position before riding.  
1. To adjust, loosen the bolts on each end of the belts.  
2. Reposition both the buckle and retractor. Tighten the bolts.  
NOTE: On the Trail Hand model, the center belt does not self adjust.  
Before riding, pull on the strap to secure the belt on the lap of the cen-  
ter passenger.

Cleaning Your Vehicle  
Keeping your vehicle clean will not only improve its appearance, but  
it can also extend the life of various components. With a few precau-  
tions, your vehicle can be cleaned much like an automobile.  
The best and safest way to clean your vehicle is with a garden hose  
and a pail of mild soap and water. Use a professional type washing  
mitten, cleaning the upper body first and the lower parts last. Rinse  
with water frequently and dry with a chamois to prevent water spots.  
NOTE: If warning decals are damaged, contact your Bush Hog deal-  
er for free replacement.  
If a high pressure type car wash system is used, extreme care must  
be taken to avoid water damage to the wheel bearings, transmission  
seals, body panels, brakes, headlights and warning decals. Many  
expensive repair bills can result from using high pressure detergent  
systems.  
NOTE: If a high pressure car wash is used, grease all zerk fittings  
immediately after washing. Also run the vehicle to evaporate any  
water that may have entered the engine or exhaust system.  
Storage  
If your vehicle is to be placed in extended or off season storage, the  
following steps should be taken to preserve its condition.  
1. Perform all necessary repairs and thoroughly clean the vehicle.  
2. Remove the spark plug and pour approximately one ounce of  
motor oil into the cylinder. Operate the starter for a few seconds  
and reinstall the spark plugs.  
3. Remove the battery. Store it in a cool, dry place out of the sun.  
4. Lubricate all suspension pivot points.  
5. Block the vehicle so all tires are suspended off the ground.  
6. Spray oil on all unpainted metal surfaces to prevent rusting.  
Avoid getting oil on rubber parts or in the brakes.  
7. Lubricate all cables.  
66

8. Tie a plastic bag over the exhaust pipe and air cleaner inlet to  
prevent moisture or small animals or insects from entering.  
9. Cover the vehicle with a canvas cover. Do not use plastic or  
coated materials since they do not allow ventilation for the vehicle.  
Removal From Storage  
1. Check the battery electrolyte level and charge the battery if nec-  
essary. Install it in the vehicle.  
2. Make sure the spark plug is tight.  
3. Fill the tank with fuel.  
4. Check all the points listed in the Pre-Ride Inspection section on  
page 29.  
NOTE: Tightness of the bolts, nuts, and other fasteners should be  
checked by an authorized Bush Hog dealer.  
5. Lubricate as outlined in the Periodic Maintenance Schedule.

Keep the battery terminals and connections free of corrosion. If clean-  
ing is necessary, remove the corrosion with a stiff wire brush. Wash

Rubber Bumper Pad Adjustment  
The plastic bed of the Utility Vehicle is equipped with two rubber  
bumper pads located at the bottom front of the bed. These rubber  
bumpers are factory adjusted to prevent rattling when the bed is in the  
down position. If adjustment should be needed at a later time proceed  
as follows:  
Manual Lift - Screw pads down enough so that slight down pressure  
on the front of the bed is needed to unlatch the lift handle.  
Electric Lift - Lower bed, then screw pads down for a snug fit to pre-  
vent rattling.
