1.
Engage the transmission bypass valves by pulling the bypass lever (a) upward
and all the way back. See Figure 36.

2.
To release the bypass lever (a), push the lever forward.
Hydrostatic Transmission
The 900 series are equipped with dual integrated hydrostatic pumps/transaxles that
are 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.
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 37.
2.
Turn the reservoir cap counter-clockwise 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. See Figure 37. DO NOT FILL
THE RESERVOIR.
3.
If necessary to add oil because of some type of leakage, 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. See Figure 38.
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.
Mower Storage
If your mower is not going to be operated for an extended period of time (30 days
to approximately six months), the mower should be prepared for storage. Store the
mower in a dry and protected location. If stored outside, cover the mower (including
the tires) to protect it from the elements. The procedures outlined below should be
performed whenever the mower is placed in storage.
1.
Change the engine oil and filter following the instructions provided in the
Engine Operator's Manual packed with this manual.
Never store the mower 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.
a.
To prevent gum deposits from forming inside the engine's carburetor
and causing possible malfunction of the engine, use a fuel stabilizer or
completely empty the fuel system for storage between 30 and 90 days:
Fuel left in the fuel tank deteriorates and will cause serious
starting problems.
• Read the product manufacturer's instructions and recommendations.
• Add to clean, fresh gasoline the correct amount of stabilizer for the
capacity of the fuel system.
• Fill the fuel tank with treated fuel and run the engine for 2-3 minutes
to get stabilized fuel into the carburetor.
b.
Emptying the fuel system for storage of more than 90 days:
• Prior to putting the mower in storage, monitor fuel consumption
with the goal of running the fuel tank empty.
