NOTE: Do not push, pull, or tow this Zero Turn Mower
without first releasing the hydraulic pressure in the Inte-
grated Transaxles.
The Transaxle hydraulic fluid Bypass Control Valves are
located on the front / inside of the transaxle on the un-
derside of the Zero Turn Mower as shown above.
Bypass Control Valves are close to
the muffler and other HOT parts.
NEVER attempt to manipulate the Bypass Control
Valves while the engine is running.
To prevent burn injury or physical injury turn the Zero
Turn Mower off and allow for a cool down period before
changing the Bypass Control Valves.
To move the zero turn mower without engine power (en-
gine off) the Bypass Control Valve must be placed in the
BYPASS position and parking brake off.
To relieve the hydraulic pressure on the transaxles, lo-
cate the Bypass Control Valve on the transaxle. Insert a
large flat blade screw driver into the slot and turn the con-
trol 90 degrees to the
BYPASS
position. This allows the
zero turn mower to be moved around without engine
power.
NOTE: The Transaxle Bypass Control Valves must be
placed back to the RUN
Position to enable the Zero Turn
Mower to move forward or backward under its engine
power.
