Throttle Control Lever
The throttle control lever is located on the right 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. See Figure 3.

Choke Control
On some models, moving the

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.

right front side of the tractor
above the drive pedal along the
