The speed limiter assembly is used on the Workman Au-
to vehicle to adjust the maximum opening of the primary
clutch moveable sheave. The vehicle speed range can
easily be adjusted with the speed range lever to limit the
maximum ground speed for operations that require a
constant speed (e.g. spraying or topdressing). The
speed range lever (Fig. 22) is used to select one of the
four (4) work−speed ranges that are used to limit maxi-
mum ground speed or a transport speed range that is
used when the machine is moved between job sites.
The speed limiter control uses a manually operated hy-
draulic cylinder to change the location of the piston in the
speed limiter cover attached to the primary clutch. The
piston location determines the maximum opening of the
primary clutch.
