The LongRanger III is
equipped with AC
BackTracker steering
Propulsion’s system.
This system is
designed to keep the
the tow vehicle whether
the vehicle is moving
forward or backward.
The trailer hitch and
ball each hold sensors
that determine the
trailer’s angle to the
vehicle. The wheels
also hold sensors that
determine the trailer’s
speed and direction
(forward or reverse).
Between these
systems a PCB
controls the directional
inputs to a servo motor
which adjusts the
wheel pitch based on
inputs. There is no
software involved in
the system.
The following pictures
show examples of each
of the components of the
BackTracker steering
system.

Note the two (2) lag
bolts and lock nuts
under the 2x2"
reciever. We added
these to eliminate all
motion from the hitch
coupling system.
This ensures that the
hitch & ball remain
rigid to the vehicle's
frame at all times.
With this modification
the trailer is perfectly
quiet behind the
vehicle and the
steering geometry
reads the precise
angle of the trailer.
