On some models, moving the
throttle lever all the way forward
activates the engine's choke
control. On all other models, the
choke control can be found on
the left side of the dash panel and is activated by pulling
the knob outward. Activating the choke control closes
the choke plate on the carburetor and aids in starting
the engine. Refer to Starting The Engine on page 13 of this
manual for detailed starting instructions.
Throttle Control Lever
The throttle control lever is
located on the left side of the
tractor's dash panel. This lever
controls the speed of the engine
and, on some models, when
pushed all the way forward, the
choke control also. When set in a
given position, the throttle will
maintain a uniform engine speed.
When operating the

clutch-brake pedal and move the speed control lever
rearward and release it into a notch.
