Tractor Operation

Tractor Operation

Hand Throttle Control Lever

The tractor is equipped with a hand throttle, located on the right console.. Rated operating speed is 2100 RPM.. Idle speed is 875 RPM.. High idle no load speed is 2225 RPM..

To increase engine speed, move the lever (1) forward (rabbit).. Pulling the lever backward will reduce engine speed (turtle)..

Fuel consumption can be reduced by operating at lower engine speeds under light load..

Decelerator Pedal

At the lower front of the right console is the decelerator pedal (4) which can be used to reduce engine speed when turning or while shifting.. When fully depressed, engine speed will drop to 1400 RPM.. If the pedal is not fully depressed, engine speed will be reduced proportionally.. When the pedal is released, engine speed will return to the previous throttle setting..

IMPORTANT: Do not release the decelerator before completing the turn. If the transmission is in a high gear, the tractor will accelerate quickly, reducing the time to correct tractor direction.

Cruise Control Operation

Cruise control automatically keeps the engine speed at a specified RPM.. Two switches control cruise mode operation.. The “CRUISE/OFF” button (2) enters and exits cruise mode.. The “+/–(SET)” button (3) adjusts the cruise setting..

When cruise mode is activated, the engine returns to the last cruise setting, if possible, based on throttle lever position..

The cruise function can be set to any engine RPM between idle and high idle, but the operating cruise RPM cannot exceed the RPM set by the hand throttle.. For example, if the cruise setting is 1800 RPM but the hand throttle is at a normal 1700 RPM position, cruise will not increase the RPM above 1700 RPM..

Operating cruise RPM always stays about 100 RPM under the normal throttle RPM setting..

Setting - Move the throttle handle higher than the desired cruise setting and press the “CRUISE” button

(2) to enter cruise operation..

The engine cruise will not engage unless the throttle lever is set to a higher operating speed than the cruise set point.. The engine speed will remain at the cruise setting RPM..

Adjust the cruise setting with the “+/–(SET)” button

(3).. Set the cruise mode with the throttle lever at Full Throttle (throttle lever fully forward) whenever possible.. Cruise function will disengage if the cruise RPM is set to a value equal to the throttle position RPM, moving the throttle to a higher position will return cruise function..

The “+/–(SET)” button will change the setting 10 RPM per momentary push.. When the button is held down, the RPM will continue to move up or down.. However, the dash RPM display will not keep up with RPM changes when the button is held down.. In this case, it is advisable to estimate the setting by ear, wait for the dash to catch up, and fine tune the RPM using momentary pushes..
