SECTION 2 - OPERATION

THROTTLE
The tractor is equipped with a hand throttle,
located on the right console. Rated operating
speed is 2100 RPM Idle speed is 850--900 RPM.
High idle no load speed varies by model from
2250 RPM to 2300 RPM.
To increase engine speed, move the lever
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.
CRUISE CONTROL OPERATION
Cruise control automatically keeps the engine
speed at a specified RPM. Two switches control
cruise mode operation. The “CRUISE/OFF”
button, 1, enters and exits cruise mode. The
“+/–(SET)” button, 2, 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, but the operating cruise RPM cannot
exceed the normal RPM for the current throttle
position. 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.
On the 2360/2425 models equipped with the
N14 the operating cruise RPM always stays
about 100 RPM under the normal throttle
position RPM.
On the models, 2290, 2335 and 2375 equipped
with the QSM 11 the cruise RPM is always less
than or equal to the normal throttle RPM.
Setting - Move the throttle handle higher than
the desired cruise setting and press the
“CRUISE” button, 1, to enter cruise operation.
On the QSM 11 engine cruise will not engage
unless the throttle is set to a higher operating
speed than the previous set point. The engine
speed will go to the RPM of the cruise setting.
Adjust the cruise setting with the “+/–(SET)”
button, 2. 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.
