OPERATION
Mowing Tips
• Find and flag rocks and other fixed objects to
avoid collisions.
• Begin with a high cutting height and reduce it
until the desired mowing result is attained. Cut
the average lawn to 2-1/2" (63.5 mm) during
the cool season and over 3" (76.2 mm) during
the hot months. For healthier and better looking
lawns, mow often after moderate growth.
• For best cutting performance, mow grass over
6" (15.2 cm) in height twice. Make the first cut
relatively high; the second to the desired height.
• The mowing result will be best with a high
engine speed (the blades rotate rapidly) and
low speed (the rider moves slowly). If the grass
is not too long and dense, the driving speed can
be increased without negatively affecting the
mowing result.
• When mowing large areas, start by turning to
the right so that clippings will discharge away
from shrubs, fences, driveways, etc. After one
or two rounds, mow in the opposite direction
making left hand turns until finished.
• The finest lawns are obtained by mowing
often. The lawn becomes more even and the
grass clippings more evenly distributed over
the mown area. The total time taken is not
increased as a higher operating speed can be
used without poor mowing results.
• Avoid mowing wet lawns. The mowing result
is poorer because the wheels sink into the soft
lawn, clumps build, and grass clippings fasten
under the cowling.
• Hose the mower deck underside with water
after each use. When cleaning, the mower deck
shall be raised into the transport position. Make
sure the mower is cooled and the engine is off.
• Use compressed air to clean top surface of
the deck. Avoid flooding water on top surface,
engine and electrical components.
• When the mulching kit is used, it is important
that the mowing interval is frequent.
WARNING! Do not make adjustments
unless:
• the engine is stopped,
• the ignition key is removed,
• the park brake is engaged
Moving Machine By Hand
Bypass Valves
Bypass valves are used to release the system so
the machine may be moved by hand when not
running.
Hydro Pumps
When pushing or pulling the mower, engage the
bypass valve on each transaxle. Tip the seat
forward to access the hydro fan cover. Pump
release valves are located at the top rear of the
pump. Use a torque wrench with an extender to
reach the valve.
The indents in the valve sit front to back when the
machine is in drive. To use bypass, turn the pump
release valve one half turn in either direction.
Reverse the procedure to reset the pump.
Load the machine into truck or trailer by driving up
ramps in low gear. DO NOT LIFT! The machine is
not intended to be lifted by hand.
WARNING! Use extreme caution when
loading the machine into a truck or trailer using
ramps. There is the possibility of serious injury
or death if the machine falls off the ramps.
