1. Engage the transmission bypass valves by pulling the bypass lever (a) upward and
all the way back (Figure 37).
a
2. To release the bypass lever (a), push the lever forward (Figure 37).
HYDRO-GEAR TRANSMISSION (IF EQUIPPED)
1. To engage the transmission bypass rods, pull the rod (a) up into the larger
opening of the key slot, then pull back until the collar on the rod passes through
the frame (Figure 38).
2. Lower the rod back into the smaller opening of the key slot, making sure the collar
is secured on the outside of the frame (b). Repeat on opposite side (Figure 38).
a
3. After moving mower, reverse Steps 1 and 2 to disengage the bypass rods.
Hydrostatic Transmission
PARKER TRANSMISSION (IF EQUIPPED)
Models with Parker hydrostatic transmissions are equipped with dual integrated
hydrostatic pumps/transaxles 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:
Check the oil level ONLY before starting the mower when the transmission
oil is fully cooled.

WARNING
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 (Figure 39).
2. Turn the reservoir cap counterclockwise to remove, 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 (Figure 39). 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 mower, the oil level in the reservoir may
be slightly higher than the maximum due to air in the oil lines. Operation of the
mower will eventually purge the air from the lines and the oil level will settle to
the maximum.
To change the transmission oil:
1. Remove the cap from the transmission oil expansion reservoir.
2. Place a suitable container under the drain plug (a) on the transmission. Remove
the drain plug (a) and allow the transmission oil to drain (Figure 40).
a
3. Using a pair of needle-nose pliers or a magnet remove the filter.
4. Replace the filter and drain plug (torque to 115-135 in-lbs) and fill through the
expansion reservoir slowly until the "FULL COLD" line. Allow the transmission oil
to move through the system and top off as necessary.
5. Replace the cap and fully tighten.
