INSTALL FRONT WHEELS
1.Raise thefrontof the tractor with a suitable hoist or
jack.
a) If a floor jack is being used, locate the jackunder
thefront axle support casting.
b) If a chain hoist is being used, attachthehoist to
the front axle and take care not to scratch thehood or
axle.
2.Place a front wheel on the spindle with the valve
stem on the outside.
3. Install thethrust washer, followed by a castle nut and
a cotter pin (SeeFigure 1-2). The castle nut should be
tight enough thatthe wheel does not wobble, but loose
enough thatthe wheel rotates freely.
Figure 1-2 Front Wheel Castle Nut and Cotter Pin
Installation
4. Install the wheel on the other side.
5. Lower the front of tractor and remove jackor hoist.
INSTALL REAR WHEELS
1. Block the front wheels to prevent the tractor from
rolling.
2. Raise the rear of the tractor using a suitable jackor
hoist. If using a floor jack,center
it under the transaxle.
Place
a block of wood between the jack and the transaxle
to prevent damage to the transaxlecase.
3. Mount eachrear wheel assembly with the valve stem
facing toward the outside.
4. Install the five lug nuts on each wheel and tighten
by hand.
5. Then tighten by torquing every other lugnut in
increments until they are all tightened to 65 ft-lbs (See
Figure 1-3).

I
Figure 1-3 Lug Nut Tightening
6. Lower the tractor and remove jackor hoist.
ADJUST TIREPRESSURE
1. Adjust the front tires with a low pressure tire gauge
to15 psifor normal operation,or 21 psi when using a
heavy front attachment.
2. Adjustthe rear tires with a low pressure tire gauge
to11 psi for normal operation, or 18 psi when using a
heavyrear attachment.
MOUNT STEERINGWHEEL
1.Check to see that the front wheels are pointing straight
ahead.
2. Using the key taped to steering wheel shaft, Place
the steering wheel onthe shaft.
3. Install the flat washer, followed by the lockwasher
and then thenut (SeeFigure 1-4).
Figure 1-4 SteeringWheel Installation
4. Snap the steering wheel insert into place.

CHECKENGINE OIL
1. Remove the dipstick andcheck the engine oil level
(SeeFigure 1-5).
Figure 1-5 DipstickRemoval
2. The top of the flattened out portionisthe full mark
and the bottom is the add mark (See Figure 1-6).
ADD OIL
Figure 1-6 Dipstick FULL and ADDMarks
3. Add oil if necessary, but neveroverfill. Use only API
Service SC oils. The chart below indicates the viscosity
to use for your climate.

CHECK HYDRAULIC FLUID
1. Check the hydraulic fluid level in the reservoir tank
(SeeFigure 1-7).
Figure 1-7 Hydraulic Fluid Reservoir Location
2. The fluid level should be between the top and the
bottom of the tank neck.
CHECK TRANSAXLE FLUID
1. Remove the transaxle filler plug and check thefluid
level on the dipstick (See Figure 1-8).
Figure 1-8 Transaxle FillerPlug
2. The level should be above the line on the dipstick
(SeeFigure
1-9).
Figure 1-9 Transaxle FillerPlug Oil Level Mark

CHAPTER 1
PRE-DELIVERY SERVICE
3.Add transaxle fluid if necessary, but do not overfill.
Use SAE 9O/Hypoid fluid only.
CHECKCOOLING SYSTEM
1. The coolant level in the reservoir bottle should be
betweenthe max. and min. marks (See Figure 1-1
0).
Figure 1-10 CoolantSystemReservoir Bottle - Coolant
Level Marks
2. If there isno fluid in the reservoir bottle, remove the
radiator cap and check to see if there is coolant in the
radiator.
3. Before adding anycoolant,check the coolant in the
engine with a hydrometer. The system should be protected
to-31°F (-35°C).
4. If necessary,add coolant to ensureadequate protection
from freezing.
CHECK WIRING
1. Visually inspect for any loose connections and tighten
as required.
2. Check the routing of wires to make sure they will not
be cut by moving parts or burned by the exhaust system.
SERVICE THE BATTERY
Electrolyteor battery
fluid are poisonousand can be injurious
to eyes,skin and clothing.In theevent
of an accident, flush immediately with
asolutionofone part baking soda to
fourpartswater and callaphysician
immediately. If baking soda is not available,
flush affectedareawithwater and call
physician immediately.
NOTE: Never install electrolyte in battery
with the battery in the tractor. Use only
an electrolyte with a specific gravityof
1.265.
1. Remove the batteryholddown strap and cover (See
Figure 1-11).
2. Remove the battery cable from the negative terminal.
3. Remove the cable
from the positive terminal and lift
thebattery from the tractor.
Figure 1-11 BatteryLocation
Remove the caps and fill eachcell until the electrolyte
(battery acid) is 1/4 inch (6mm) above the top edge of
the plates or 1/8 inch (3mm) above the top ofthe
separators.
5. Allow thebattery to stand for 5 to 6 hours. During
thistimethe acid level will drop,and should be restored
to the original level.
6. For the first time, charge the batteryat 1 amp for
about 15 hours.
NEVER CHARGE WITH A BOOSTER
CURRENT FOR THE FIRST CHARGE. The battery caps
should always be
off when charging.
7. Two hours after charging, restore the fluid level with
distilled water.
NOTE: After the battery hasbeen in service,
add 'only distilled water.
DONOTADD
ELECTROLYTE TO A USED BATTERY.
8. Install thebattery in the tractor with the terminal post
side toward the front, or closest to the engine.
9. Connect the positive battery cable first.
10. Connect the negative battery cable.
11.Coat the exposed metal portions with battery grease.
12. Install 'thebattery coverand hold down strap.
FILL THE FUEL TANK
1. Fill the fuel tank with regulargasoline (90 octane or
higher).
2. Check fuel hoses and fittings for leaks.
LUBRICATETRACTOR
1. Grease 'all the lube pointsmentioned inthe Body
Lubrication section on page
2-6.
TESTTRACTOR'S OPERATION
1. Start the engine. The starting procedures are given in
detail on page
4 ofthe Owner's Manual.
2.Check the operation of all gauges and indicator lights.

3. Check to see that the parking brake light comes on
whenthe
key is pushed in and the parking brake lever
is positively engaged.
4. Test the operation of the lights,
5. Check thelift cylinder to see if the mid hydraulic lift
is operating (See Figure 1-1 2).
Figure 1 - 12 Mid-HydraulicLiftCylinder
6. Test the PTO clutch (See Figure 1-13).
Figure 1-1 3 Power Take Off (PTO) Clutch
7. Test drive the tractor, using boththeforward and
reversegears.
CHECK FRONT WHEEL ALIGNMENT
1.Set the front wheels pointing straight ahead.
2. Each wheel should have approximately 3/64 inch of
"toe in".
ATTACHOWNER'SMANUAL TO TRACTOR
1. Attachtheowner's manualand the manual of
attachments and accessories to the tractor.
