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.
Purchase bulk electrolyte with 1.260 specific gravity from a
local battery supply outlet.
Important Never fill the battery with electrolyte while
the battery is installed in the tractor. Electrolyte could be
spilled on other parts and corrode them.

poison that can severely burn you and others.
• 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.

Important Do not overfill the battery because
electrolyte (sulfuric acid) can severely corrode and damage
the chassis.
4. Wait 5 to 10 minutes after filling the battery cells.
5. Add electrolyte, if necessary, until the electrolyte level
is up to the Upper line (Fig. 1) on the battery case.
6. Install the battery vent caps.
7. Charge the battery for 10 to 15 minutes at 25 to

The tractor comes from the factory with oil in the engine
crankcase; however, you may be need to add oil. Refer to
the Operator’s Manual for oil type, viscosity, and crankcase
capacity. Add only enough oil to raise the level to the Full
mark on the dipstick.
Checking the Tire Pressure
Check the tires to ensure that they are inflated to the proper
level. Refer to the Operator’s Manual.
Checking the Mower
Adjustment
For 32 Mowers only
The mower was leveled at the factory. However, if the
mower is not cutting level, adjust the side-to-side level and
the front-to-rear blade slope. See the Operator’s Manual.
Warning
An improperly adjusted mower can cause the
drive belt to engage the blade at the highest
height-of-cut setting when the blade control (PTO)
lever is in the Disengaged position. Operating the
mower at the highest height-of-cut setting during
or soon after setup may expose you or others to a
rotating blade, causing injury or death.

Warning
Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks and
flames away from battery.
8. When the battery is fully charged, unplug the charger
from the electrical outlet, then disconnect the charger
leads from the battery posts (Fig. 2).
Never put your hands or feet under the mower or
through any openings in the mower.
To ensure that the mower is properly functioning at the
highest height-of-cut setting during or soon after setup, do
the following:
1. Raise the mower to the highest height-of-cut setting.
2. Ensure that the blade control (PTO) lever is in the
Disengaged position.
3. Start the engine and have someone check if the drive
belt engages or tries to engage the blade.
4. If the drive belt tries to engage or engages the blade,
operate the mower for several minutes at different
height-of-cut settings.

Note: The length of the long rod extending out of the front
of the adjusting block on the sides of the chassis (Fig. 3) is
set to 3/4 in. (19 mm) at the factory.

Ensure that all of the necessary points on the tractor are
lubricated; refer to the Operator’s Manual.
Checking the Safety Interlock
System
Refer to the Operator’s Manual.
Purging the Hydro Transaxle
For Hydro Drive Tractors only
Ensure that the neutral position is set properly. If the tractor
moves when the traction control pedal is not depressed,
adjust the neutral position.
1. Run the engine at a low idle and move the traction
control pedal forward, then release it.
2. Move the traction control pedal to reverse, then release.
If the tractor moves while it is in the Neutral position,
do the following:
3. Run the tractor for 5 to 10 minutes to warm up the
transaxle.
4. Disengage the blade (PTO).
5. Set the parking brake.
6. Stop the engine and wait for all moving parts to stop.
7. Remove the ignition key.
8. Raise the right rear wheel off the ground and support it
with a jack stand.
Note: Ensure that the left rear wheel is on the ground.
Danger
Shipping and handling can introduce air into the hydro
transaxle. For proper performance, remove all trapped air.
1. Move the tractor to a flat, level surface.
2. Move the drive control in the Push position (Fig. 4).

10.Start the engine and run it at full throttle.
11. Rotate the adjusting puck in both directions until you
find the midpoint where the axle no longer rotates
forward or reverse.
12.Hold the puck with an adjustable wrench so that it will
not move and torque the adjusting puck screw to 21 to
27 ft-lb (28 to 36 N•m).
13.Stop the engine and wait for all moving parts to stop.
14.Remove the ignition key.
15.Lower the tractor from the jack stand.
16.Check the adjustment again by repeating step 1.
Checking the Traction Control
Pedal
For Hydro Drive Tractors only
You can adjust the traction control pedal for optimum
forward and reverse speeds.
1. Loosen the screws below the right footrest.

1. If either of the above conditions exist, turn the engine
off and ensure that the belt guides are no more than
1/8 inch away from the engine and the transmission
pulleys.
2. Check the cable tension. The cable should be taught and
have 1/2 in. (13 mm) movement when you apply a
slight pressure to the cable (Fig. 8).

3. Move the ground speed lever and note the gap between
the lever and the edge of the gate. There should be
about 1/4 in. (6 mm) of free play before the cable is
taught.
4. Adjust the cable tension by loosening the front cable
guide located on tractor brace above the pulley.
5. Slide the guide sideways as needed for proper tension
(Fig. 8).
Test Driving the Tractor
To ensure that all electrical and mechanical systems are
operating properly, see the Operator’s Manual.
Adjust the shift cable if either the ground speed lever does
not shift firmly toward the numbers on the shift plate when
you release the lever or if it is difficult to shift on-the-go
(Fig. 7).
