Cruise Control Switches
There are two cruise control switches on panel to right of
operator (Fig. 17)—one for ON/OFF control, the other for
cruise engagement. Cruise control operation, when in either
high range or low range mode, is disengaged either by
actuating the brake pedal or turning the switch to OFF
position.
High Range/Low Range Ground Speed
Switch
This single lever (Fig. 17) allows selection of either high or
low range ground speeds. Push switch forward for High
Range or pull back for Low Range. Switch returns to
neutral position. Switch automatically resets to Low Range
when a cutting unit is lowered, front cutting unit is not fully
raised or if engine is shut off.
Cutting Unit Lift Controls
The two outside levers raise and lower the outside cutting
units, the center lever raises and lowers the front unit
(Fig. 17). 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 control levers actuated until cutting units pass
over 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 mowers, do not allow 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
The glow plug indicator (Fig. 17) automatically actuates
proper glow period when ignition key is turned to ON
position. Illuminates when glow plugs are actuated. When
glow plugs are heated sufficiently, light goes off indicating
engine is ready to start.
Deck Drive/PTO Switch
Pull sleeve upward on switch lever (Fig. 17) and push lever
to ENGAGE position and release to actuate switch; lever
will move to neutral position when released. Move lever to
DISENGAGE position to stop. Switch automatically resets
to DISENGAGE when all three cutting units are raised or
engine is shut off.
