Operating Instructions

Engine Throttle

The throttle control lever (red knob) is located on the
left side of the seat and is used to control engine
speed. Moving the lever forward toward the FAST
position increases engine speed; moving it back-
ward toward the IDLE position decreases engine
speed.

Forward Speed Control (FSC)

Forward Speed Control (FSC) has two functions:
One is to set forward travel speed, and the other is to
establish the NEUTRAL-PARK position. When the
FSC lever is moved into the FORWARD position, a
friction lock holds any forward speed setting from
0 to 10 mph (0 to 16 km/h). The ground speed is pro-
portional to the lever position; the further the lever is
advanced forward, the faster the tractor moves. It is
not necessary to hold the FSC in position since the
friction lock maintains the selected lever position.
Pulling back on the steering levers overrides the
FSC setting and slows or stops forward travel. Re-
leasing the steering levers allows the tractor to re-
sume forward travel at the speed set by the FSC le-
ver. To stop and park the machine, the FSC lever is
moved backward to the NEUTRAL-PARK position.

Fuel Pump Priming

Engine is equipped with a mechanical fuel pump
and the fuel system will need to be primed in certain
conditions (after running out of fuel or after fuel sys-
tem maintenance). Move priming lever on fuel pump
until the clear cup on the fuel filter/water separator
shows filled with fuel before attempting to crank the
engine.
NOTE: DO NOT crank the engine to prime the fuel
system as this may damage the starter from pro-
longed cranking.
