Using the Transmission Bypass Rods
If for any reason the tractor will not drive or you wish to move the
tractor, the two hydrostatic transmissions are equipped with a bypass
rod that will allow you to manually move the tractor short distances.
WARNING!
bypass rod engaged. Serious transmission damage
will result from doing so.
1. From the rear of the tractor, just inside the two rear tires,
locate the transmission bypass rods. Refer to Figure 6-3.
WARNING!
rods when the engine is running or hot.
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 6-3.
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 6-3.

Hydrostatic Transmission
Your zero turn tractor is equipped with dual integrated
hydrostatic pumps/transaxles that are sealed and are
maintenance-free. However, this model is equipped with a
transmission oil expansion reservoir. Under normal operating
conditions, the oil level in the expansion reservoir does not need
to be checked and no additional oil is needed. If checking the
reservoir oil level, proceed as follows:
WARNING!
Check the oil level ONLY before
starting the tractor when the transmission oil is fully
cooled.
1. Pivot the operator's seat forward and clean the reservoir
cap and the area around the cap to prevent debris from
contaminating the transmission oil. See Figure 6-4.
Figure 6-4
2. Turn the reservoir cap counterclockwise to re-move, then
check the oil level in the reservoir. Oil should be visible at
the bottom of the cup, but the oil level must NOT be above
the "FULL COLD" line. See Figure 6-4. DO NOT FILL THE
RESERVOIR.
3. If necessary to add oil because of some type of leakage, use a
quality 20W50 motor oil and add only enough oil to bring the
level to the "FULL COLD" line. Reinstall the cap and fully tighten.
NOTE: Prior to the initial operation of the tractor, the
oil level in the reservoir may be slightly higher than the
maximum due to air in the oil lines. Operation of the tractor
will eventually purge the air from the lines and the oil level
will settle to the maximum.
