Should your truck become immobilized in an Automatic Traction
Control equipped tractor, please be advised that wheel spin upon gear
engagement is a normal condition. The tractor must be accelerated to a
speedometer reading of 5 to 10 mph before the ATC controller recognizes
an event, thereby activating the foundation brakes and engine torque
reduction. You may feel a vibration or shudder prior to engagement of
the wheel positions that continue to have traction, which should result in
extraction from the immobilized condition.

Optional Deep Snow and Mud Switch
ATC includes a deep snow and mud option. This function increases
available traction on extra soft surfaces like snow, mud, or gravel by
slightly increasing the permissible wheel spin. The deep snow and
mud option is NOT automatic. Drivers use a switch to select this
feature. When this feature is selected, the ATC lamp blinks slowly and
continuously. Once the feature is no longer required, drivers use that
same switch to turn the option off.

Roll Stability Control
Many of our tractors are equipped with Roll Stability Control. This
system works in conjunction with the ATC feature and can take control
of the engine throttle and tractor braking system whenever thresholds
specific to lateral acceleration (sideways movement) or yaw (steering
angle) are exceeded. The driver will be notified by an indicator lamp
illumination, automatic reduction of throttle, and the application of
brakes on one or more wheel end positions. All of these features acting
together can assist in maintaining control of the tractor and can actually
help avoid a roll over or a jackknife. If there is any question as to whether
your tractor has this option, please contact maintenance personnel for
verification.
