Controls
Cutting Unit Lift Controls (Fig. 16)—The two outside
levers raise and lower the outside cutting units; the center
lever raises and lowers the front unit. The engine must be
running to lower and raise cutting units. Cutting unit blades
automatically stop whenever the cutting units are raised.
When lowering outside cutting units, keep the control levers
actuated until the cutting units pass over the center. Units
will then "float" down to the turf.
Note: Holding the cutting unit levers in the actuated
position while the units are lowering could drive them
forcefully into the turf and cause cutting unit damage. After
lowering the mowers, do not allow the levers to snap back
to neutral. This could cause the levers to go past neutral,
lock the cutting units in a non-float mode and prevent them
from following turf contours.
Glow Plug Indicator (Fig. 16)—Automatically actuates
the proper glow period when the ignition key is turned to
the ON position. Illuminates when glow plugs are actuated.
When glow plugs are heated sufficiently, the light goes off,
indicating the engine is ready to start.
Deck Drive/PTO Switch (Fig. 16)—Pull the sleeve upward
on the switch lever and push the lever to the ENGAGE
position and release it to actuate the switch; the lever will
move to the neutral position when released. Move the lever
to the DISENGAGE position to stop. The switch
automatically resets to DISENGAGE when all three cutting
units are raised or the engine is shut off.
Engine Over-ride Switch (Fig. 16 & 17)—If the engine
has overheated and been shut-down by the safety switch,
depressing the button will allow engine operation. Use the
button only for emergencies and only at short intervals.

Electrical System—Fuse block (Fig. 18)—The electrical
system is protected by one 5 Amp and two 15 Amp fuses
located under the control panel to the operator's right. A
fusible link, located by starter, is incorporated for the
protection of the entire wiring circuit. The link can be
replaced if total loss of electrical function results. However,
the reason for the malfunction should first be found and

corrected.

Traction Pedal (Fig. 19)—Controls forward and reverse
operation. Depress the top of the pedal to move forward and
the bottom to move in reverse. Ground speed depends on
high-range/low-range ground speed mode (slower in low
than high range) and proportionate to how far the pedal is
depressed.
Steering/Parking Brake Pedals (Fig. 19)—The left and
right turn pedals are connected to the front wheel brakes.
Since both brakes work independently, they can be used to
turn the machine more sharply or to increase traction if one
wheel tends to slip while operating on a hillside. However,
wet grass or soft turf can be damaged when brakes are used
for turning. A brake latch lever locks the two pedals
together for parking. Whenever the engine is shut off, set
the parking brake to prevent accidental machine movement.
Latch the pedals together, depress them and pull the parking
brake knob at the top of the steering tower up (Fig. 15).
Depress the brake pedals to release the parking brake.
