Operating Instructions25Engine ChokeThe choke control lever (black knob) is located onthe left side of the seat. To start a cold engine, movethe choke control forward to the ON position. Afterengine starts, move choke control toward the OFFposition, keeping enough choke to allow the engineto run smoothly as it warms up. As soon as possible,move the choke to the OFF position. A warm enginerequires little or no choke for starting.IMPORTANT: Make sure the choke is in the OFFposition during normal engine operation; runningwith the choke in the ON position CAN damage theengine.Engine ThrottleThe throttle control lever (red knob) is located on theleft side of the seat and is used to control enginespeed. Moving the lever forward toward the FASTposition increases engine speed; moving it back-ward toward the IDLE position decreases enginespeed.Choke and Throttle LocationForward Speed Control (FSC)Forward Speed Control (FSC) has two functions:One is to set forward travel speed, and the other isto establish the NEUTRAL-PARK position. Whenthe FSC lever is moved into the FORWARD position,a friction lock holds any forward speed setting from0 to 7 mph (0 to 11.3 km/h). The ground speed is pro-portional to the lever position; the further the lever isadvanced forward, the faster the tractor moves. It isnot necessary to hold the FSC in position since thefriction lock maintains the selected lever position.Pulling back on the steering levers overrides theFSC setting and slows or stops forward travel.Releasing the steering levers allows the tractor toresume forward travel at the speed set by the FSClever. To stop and park the machine, the FSC leveris moved backward to the NEUTRAL-PARKposition.Steering LeversEach drive wheel is controlled by its own indepen-dent steering lever, for both steering function andFORWARD/REVERSE motion. The FSC lever setsthe maximum forward speed, and also sets the for-ward position of the steering levers. The steeringlevers operate only with a backward pulling move-ment of the lever, which causes the drive wheel forthat lever to first slow down, stop, and then reversewith a full backward lever stroke. The levers arereleased to the FORWARD position for “straight-ahead” ground travel.NOTE: Pushing forward on the steering levers willnot cause any change in tractor motion - there will beno steering lever reaction and there will be nomachine damage.PTO SwitchThe PTO toggle switch is located on the RH front ofthe body and has two positions: ON (ENGAGE) andOFF (DISENGAGE) - positioning switch "ON" acti-vates the electromagnetic blade drive clutch whilethe blade brake is applied when the switch is movedto "OFF".ChokeThrottle
