SAFETY INTERLOCK SYSTEM (cont’d)
If the system fails any of these tests, you will
need to troubleshoot the system. The 260
series Electrical Demystification Guide (form no.
492-4404) describes how to test individual
switches and circuits.
CRUISE CONTROL
General Information
The 520xi and larger tractors are equipped with
an electric cruise control that, when activated,
locks the motion control lever in position to
maintain a constant speed. The Smart Turn
Steering system overrides the cruise control in
a sharp turn slowing the tractor until the turn is
completed. The tractor then accelerates to
resume the set speed.
Theory of Operation
The cruise control is activated with a switch
located on the right side fender. When the
tractor is at the desired speed, activating the
switch energizes an electromagnet.
