Check Tire Pressure
Check front and rear tire pressure. Set to 12 psi
(83 kPa).
Install Steering Wheel
1. Move front wheels straight ahead.
2. Slide the steering wheel over shaft. Line up the
hole in the steering wheel with the hole in the
shaft (Fig. 2). From the seat you should be able
to read the brand logo on the steering wheel.
3. To align the holes, insert a punch or long nail
partially through the holes in the steering wheel
and shaft. Then insert the spirol pin into the hole
on the opposite side.
4. Using a hammer, drive the spirol pin in until it is
flush with the outside of the steering wheel
(Fig. 2).

Activate the Battery
Bulk electrolyte with 1.260 specific gravity must be
purchased from a local battery supply outlet.
1. Remove the battery and battery box from the
tractor: refer to Operator’s Manual, Removing
the Battery.
IMPORTANT: Be careful not to damage the
long vent tube when removing the battery
box.
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.
2. Unscrew six filler caps from the battery. Slowly
pour electrolyte into each cell until the level is
up to the “UPPER” line on the battery case
(Fig. 4).

POTENTIAL HAZARD
•Charging battery produces gasses.
WHAT CAN HAPPEN
•Battery gasses can explode.
HOW TO AVOID THE HAZARD
•Keep cigarettes, sparks and flames away
from battery.
4. When the battery is fully charged, disconnect the
charger from the electrical outlet and from the
negative and positive battery posts (Fig. 5).
5. Slowly pour electrolyte into each cell until the
level is once again up to the “UPPER” line on
the battery case (Fig. 4).
6. Install the battery and battery box in the tractor:
refer to the Operator’s Manual, Installing the
Battery.
Fill Crankcase with Oil
The tractor is shipped from the factory without oil in
the engine crankcase: refer to the Operator’s Manual,
Engine Oil Specifications for oil type, viscosity, and
crankcase capacity. Only add about 80% of the
specified amount of oil. Then check the oil level and
add only enough oil to raise the level to the “FULL”
mark on the dipstick.
Mower Discharge Chute
Remove roll pin from discharge sure spring and
discard. This is for shipment only. Make sure spring
returns discharge chute to the full down position.
Level the Mower
Level the mower from side-to-side and set
front-to-rear blade slope. Refer to the Operator’s
Manual, Side-to-Side Mower Leveling and
Front-to-Rear Blade Slope.
Lubricate the Tractor
Refer to the Operator’s Manual, Greasing and
Lubrication.
Insert Key into Switch
Check Safety System
Refer to the Operator’s Manual, Checking Safety
System.

Purge Hydro Transaxle
(Hydro Drive Tractors Only)
During handling and shipping air can be introduced
into the hydro transaxle. To achieve proper
performance all trapped air must be removed.
1. Place tractor on a flat level surface.
2. Place the drive control in the “Push” position
(Fig. 6).

3. Run engine at a low idle and move traction
control pedal forward for five (5) seconds then
reverse for five (5) seconds. Repeat three (3)
times.
4. Place the drive control in the “Operate” position
(Fig. 6). Drive the tractor forward then reverse
approximately five (5) feet. Repeat three (3)
times.
Check Hydro Neutral Position
(Hydro Drive Tractors Only)
Adjustment is required if the tractor creeps without
the traction control pedal being depressed.
1. Run engine at a low idle and move traction
control pedal forward, then release. Move
traction control pedal reverse, then release. If the
tractor creeps adjust as follows:
2. Raise the rear wheels off the ground and support
with jackstands.
3. Loosen locknut securing adjustment (Fig. 7).
4. Move adjustment stud up or down until creep is
minimized (Fig. 7). There may still be some
wheel rotation with wheels off the ground.
5. Tighten the locknut (Fig. 7). Move the traction
control pedal forward and reverse and allow it to
center. Verify that there is no creep with the
wheels on the ground.

Check Traction Control Pedal
(Hydro Drive Tractors Only)
After adjusting the hydro neutral position it is
necessary to check the traction control pedal. While
pressing the control pedal full forward and full
reverse it must not contact the footrest pad before
hitting the stop(s) at the transaxle (Fig. 7).
1. If contact is made with the foot pad, before
hitting stop(s) on transaxle (Fig. 7), in either
forward or reverse directions, adjustment is
required.
2. Loosen the capscrews below the right footrest.
Slide the pedal in the slots away from the
direction that made contact with the footrest
(Fig. 8).
3. Tighten capscrews and recheck traction control
pedal for contact with stop(s) on transaxle and
footrest.

Check Shift Cable Adjustment
(Gear Drive Tractors Only)
Cable adjustment is required if the ground speed

1. If either of the above conditions exist, check that
belt guides are positioned no more than 1/8 inch
away from the engine and transmission pulleys.
2. Check the cable tension. Cable should be taught
and have 1/2 inch movement with slight pressure
applied (Fig. 10).

3. Move gear select lever and note gap between
lever and edge of gate. There should be about
1/4 inch of free play before cable is taught.
4. To adjust the cable tension loosen the front cable
guide, located on tractor brace above deck
pulley. Slide guide sideways as required for
proper tension (Fig. 10).
