Magnet Assembly - Cruise Control
Purpose
When engaging cruise control, the magnet assembly
engages a cruise control plate that locks the control
linkage to the speed that is set (Figure 235).
Location
The magnet assembly is located in the right rear of the
tractor. The seat, fender, and fuel tank needs to be
removed to gain access to the magnet assembly.

How It Works
When the desired forward speed is obtained, push the
cruise control switch on the dash. Through a cruise
control relay, 12 volts is sent to the magnet assembly
and this locks the magnet to the cruise control plate
and locks the traction control. This allows you to
remove your foot from the traction control.

Figure 236
How It Works
The switch has contacts inside which connect two
terminals in one position while disconnecting then in
the other. There are 3 positions to the switch; OFF,
START, and RUN. The start position is spring loaded
so that the switch automatically returns to the "RUN"
position.
