OPERATING INSTRUCTIONS
NOTE: To begin motion the operator must be in the seat and the brake disengaged before
the levers can be moved from the neutral slots or the engine will kill.
By moving the levers an equal amount forward or back the mower will move in a straight line
in that direction.
Movement of the right lever forward will cause the right wheel to rotate in a forward direction.
Movement of the left lever forward will cause the left wheel to rotate in a forward direction. To
stop forward travel pull levers back into the neutral position.
To turn right while moving in a forward direction pull the right lever back towards the neutral
position, this will slow the right wheel and cause the mower to turn in that direction.
To turn left while moving in forward direction pull the left lever back towards the neutral
position, this will slow the left wheel and cause the mower to turn in that direction.
To zero turn pull one lever back beyond neutral while holding the other slightly ahead of
neutral. NOTE: The direction of the zero turn will be determined by which lever is pulled back
beyond neutral. Thus, left lever back, left turn and opposite for right turn. Use caution when
using this maneuver unit can spin very rapidly if one lever is positioned too much
ahead of the other.

MAINTENANCE
1. Engine oil level: Check daily with engine cold and on a flat surface. Remove the dipstick and
wipe clean. Reinsert the dipstick all the way,but do not screw down. Remove the dipstick and
check oil level. If oil level is low add oil. Use engine manufacturers specs for type of oil.
2. Pump drive belt compartment: Stop engine and remove key. Tilt seat forward and clean all
debris from inside. NOTE: Cleaning may need to be done more frequently in dry conditions.
3. Mower blades: Stop engine and remove key. Inspect blades and sharpen or replace as needed.
Check daily or more often if needed. The machine requires more power with dull blades and
gives a poor cut. If blades get bent, replace them. Blades shouldn’t have any notches from
hitting objects. The air foil on top of the blade should be sufficient to raise the grass for cutting. If
blades are in good condition, sharpen at an angle of 22 to 28 degrees about 2-1/2 inches in from
the tips. Note: After sharpening, check blades for proper balance, if needed correct balance to
prevent excessive vibration.
4. Safety interlock system: Check daily and never operate the mower if this system is not
functioning properly. The starter should crank only when the operator is in the seat, the park
brake set, blades off and the motion control levers in the neutral slots. If the mower starts with
any of these controls on or in an operating position, turn the mower off and repair the system
immediately.

MAINTENANCE
5. Hardware: Stop engine and remove key thoroughly inspect the entire machine for any
missing or loose hardware. Check daily.
6. Air cleaner: Stop engine and remove key. Remove plastic cover and loosen wingnut on the
air cleaner. Remove the foam pre-cleaner and wash or replace if needed. Inspect paper filter
and replace if dirty. Check every 25 hours, daily if in very dirty conditions. Fuel efficiency,
engine RPM, and available power goes down rapidly if the air filter is dirty. Prolonged effects
could damage the engine.
7. Engine oil: Change oil to manufacturers specifications. Stop engine and remove key. Drain
oil when engine is warm. Thoroughly clean around cap before removing. Remove oil
drain cap from the right side of engine block and replace drain cap. Remove oil filter and replace. Put a light coat of clean oil on the filter gasket before installing. Fill engine with oil using
manufacturers specs, see Kawasaki owner’s manual. Start engine and idle slowly to allow the oil
to recoat the interior of the engine and then inspect for leaks.
8. Hydraulic oil: Check daily. Stop engine and tilt seat forward.Thoroughly clean around
cap. Remove cap. Oil level should be even with the top of the baffle in the tank. If not, add oil.
NOTE: Use only 20w - 50 motor oil.
9. Tire pressure: Check every 25 to 50 hours. All four tires require 15 psi.
10. Battery: Maintance free
11. Belts: Check every 25 hours. Stop engine and remove key. Check the condition of all
belts.
12. Lubrication (every 25 hours):
Front caster pivots
Front wheels
Motion Control Brackets Left and Right
Pump idler pivot
Deck idler pivot
Strut pivot pins
(Clean grease zerk thoroughly before greasing)
12
MAINTENANCE
13. Fuel filter: Replace annually or as needed.
14. Hydraulic filter and oil: Change every 500 hours or yearly. Stop engine and remove key.
Clean around the filter and the drain plug on the bottom side of the tank. Remove the filter and
allow any oil to drain from the filter head. Then replace with new filter. Use only Yazoo/Kees p/n
102606, filter which has a bypass valve and the correct micron filter. Remove drain plug under
hydraulic tank and allow tank to drain, reinstall drain plug. Fill tank with 20w - 50 motor oil to the
top of the baffle in the tank and replace cap. Block up the rear of unit until wheels will rotate freely
and start engine at a slow idle, move the motion control levers forward and run for several minutes. Stop engine and recheck oil level. If wheels don’t response an air lock has occured within
the hydraulic system. Bleed air from lines, or let stand overnight to allow the air time to dissipate
out of the oil. Retry responses & check the oil level. Note: Serious damage to the pumps and
wheel motors can occur if the system is ran with an air lock.
