Checking Front Wheel Toe–In

sure the front wheel toe-in is between 1/8” and 1/4”.
For instructions on adjusting toe-in, refer to the
Maintenance section in Operator’s Manual.

Check to Insure that Steering
Linkage is Centered
1. With the tractor on a level surface, turn the
steering wheel fully to the left and check the
clearance of the left hand spindle stop to the stop
on the front axle. There should be a slight
clearance between the stops (Fig. 3).

2. Repeat for the right front tire in a right turn.
3. If the stops on one side hit, and on the other side
have clearance, shorten the tie rod on the side
that hits, and equally lengthen the tie rod on the
opposite side until both sides have clearance.
Recheck the toe in.
Checking Tire Pressure
Check front and rear tire pressure. The correct front
and rear tire pressure is 20 psi (138 kPa).
Activating the Battery
POTENTIAL HAZARD
•Battery electrolyte contains sulfuric acid
which is a deadly poison and it causes
severe burns.
WHAT CAN HAPPEN
•If you carelessly drink electrolyte you could
die or if it gets onto your skin you will be
burned.
HOW TO AVOID THE HAZARD
•Do not drink electrolyte and avoid contact
with skin, eyes or clothing. Wear safety
glasses to shield your eyes and rubber
gloves to protect your hands.
•Fill the battery where clean water is always
available for flushing the skin.
•Follow all instructions and comply with all
safety messages on the electrolyte container.
1. Remove the battery from the tractor (refer to
Removing the Battery in your tractor Operator’s
Manual).
Note: Never fill the battery electrolyte with
the battery installed in the tractor.
2. Remove the filler caps from the battery. Slowly
pour electrolyte into each cell until the
electrolyte level is up to the lower part of the
tube (Fig. 4). Use an electrolyte with a specific
gravity of 1.265.

battery charger to the battery posts (Fig. 5).
Charge the battery at a rate of 4 amperes or less
for 4 hours (12 volts).

Checking the Wiring and
Fasteners
•Inspect the tractor for any loose electrical
connections and secure them as required. Check
the wire routing to make sure moving parts do
not interfere with wires and cause a short.
•Assure all fasteners are tight.
Burnishing the Clutch
The following break–in procedure must be performed
as part of pre–delivery service or when a new clutch
is installed.
Note: There must be a PTO driven
attachment installed to provide a load
in order to burnish the clutch facings
properly.
1. Run the engine at full throttle and engage the
clutch bringing the load to full speed. Then
disengage the clutch.
2. Let the load come to a full stop, then engage
again.
3. Repeat these procedures (1 and 2) 5 times.
Test Driving the Tractor
1. Check the oil level in the crankcase (refer to
Engine Oil in your tractor Operator’s Manual for
oil type, viscosity and crankcase capacity).
Note: When checking the oil level, slide the
dipstick all the way into the filler tube,
but do not screw the dipstick onto the
filler tube.
2. Check the oil level in the transaxle (refer to
Transaxle Fluid in your tractor Operator’s
Manual for oil type, viscosity and capacity).
3. Check to make sure all lubrication points have
been greased as shown in the Maintenance
section of tractor Operator’s Manual.
4. Fill the tank with unleaded regular gasoline with
an octane rating of at least 85. Open the fuel
shutoff valve and check the fuel hose and fittings
for leaks.
