2. Engage the transmission bypass rods, one on each side of
the tractor, to move the tractor manually without starting
it. The transmission bypass rods are located on the rear of
the tractor, just inside each rear wheel. Engage the bypass
rods by pulling each one out (a) and to the right (b) to lock
it into place. See Figure 6-2.
NOTE:
The tractor will not drive with the bypass rods in the
engage position.
3. Disengage the bypass rods by reversing steps a & b after
moving the tractor. See Figure 6-2.
Hydrostatic Transmission
The hydrostatic transmission is sealed at the factory and is
maintenance-free. The fluid level cannot be checked and the
fluid cannot be changed.
Tractor Storage
If your tractor is not going to be operated for an extended period
of time (thirty days to approximately six months), the tractor should
be prepared for storage. Store the tractor in a dry and protected
location. If stored outside, cover the tractor (including the tires) to
protect it from the elements. The procedures outlined below should
be performed whenever the tractor is placed in storage.
1. Change the engine oil and filter following the instructions
provided in the engine manual packed with this manual.
WARNING!
Never store the tractor with fuel in the
tank indoors or in poorly ventilated enclosures, where
fuel fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer, etc.
2. If storing the tractor for 30 days or more:
a. To prevent gum deposits from forming inside
the engine’s carburetor and causing possible
malfunction of the engine, the fuel system must be
either completely emptied, or the gasoline must be
treated with a stabilizer to prevent deterioration.
WARNING!
Fuel left in the fuel tank deteriorates
and will cause serious starting problems.
b. Using a fuel stabilizer such as
STA-BIL®
for storage
between 30 and 90 days:
t Read the product manufacturer’s instructions
and recommendations.
t
Add to clean, fresh gasoline the correct
amount of stabilizer for the capacity
(approximately 3 gallons) of the fuel system.
t Fill the fuel tank with treated fuel and run the
engine for 2-3 minutes to get stabilized fuel
into the carburetor.
c. Emptying the fuel system for storage of more than
90 days:
t Prior to putting the tractor in storage, monitor
fuel consumption with the goal of running
the fuel tank empty.
t
Run the engine until it begins to stall. Use the
choke to keep the engine running until all fuel
in the carburetor has been exhausted.
t Referring to the engine manual, drain the fuel
from the carburetor bowl.
3. Clean the engine and the entire tractor thoroughly.
4. Fully charge the battery, then disconnect the negative
cable at the battery to prevent possible discharge.
Recharge the battery periodically when in storage.
NOTE:
Remove the battery if exposed to prolonged periods
of sub-freezing temperatures. Store in a cool, dry location
where temperatures are above freezing.
5. Lubricate all lubrication points.
NOTE:
Using a pressure washer or garden hose is not
recommended for cleaning your tractor. It may cause
damage to electrical components, spindles, pulleys,
bearings or the engine. The use of water will result in
shortened life and reduce serviceability.
Removing The Tractor From Storage
1. Check the engine oil.
2. Fully charge the battery and inflate the tires to the
recommended pressure.
3. Fill the fuel tank with clean, fresh gasoline.
4. Start the engine and allow to idle for a few minutes to
ensure engine is operating properly.
5. Drive the tractor without a load to make certain all the
tractor systems are functioning properly.
Adjustments
WARNING!
Shut the engine off, remove the
ignition key and engage the parking brake before
making adjustments. Protect your hands by using
heavy gloves when handling the blades.
Adjusting RH & LH Drive Control Levers
The RH and LH drive control levers can be adjusted up or down
and forward or backward for the comfort of the operator.
The drive control levers can be placed in either of two height
positions, and/or can be moved forward or rearward within the
range of the slot in each lower arm..
To adjust the drive control lever height, proceed as follows:
1. Remove the upper hex screw and flat washer securing the
lever to the pivot bracket.
2. While supporting the control lever to keep it from falling,
remove the hex screw and flat washer from the bottom of the
control lever and lower arm. Refer to Figure 6-3.
3. Reposition the control lever to align with the other set of holes
in the lower arm and insert the hex screw through the flat
washer and into the lower arm. Tighten the hex screw until
snug.
4. Insert the hex screw through the flat washer and through
the control lever slot and the lower arm. Do not tighten
now.
5. If you are going to adjust the control levers forward or rearward,
proceed to the next step. If not, fully tighten the hex screw.
