Automatic swinging drawbar system
First Claim
1. An automatic swinging drawbar system, comprising:
- a swinging drawbar having a front end pivotally attached to a tractor and a rear portion slidably supported by a rear support of said tractor;
a first actuator connected to said swinging drawbar;
a second actuator connected to said swinging drawbar on a side opposite of said first actuator; and
a control unit for controlling the operation of said actuators to control said rotational position of said swinging drawbar, wherein said control unit monitors a rotational position and movement of a steering wheel.

Abstract
An automatic swinging drawbar system for efficiently and automatically controlling a tractor'"'"'s swinging drawbar. The automatic swinging drawbar system includes a swinging drawbar, a first actuator connected to the swinging drawbar, a second actuator connected to the swinging drawbar, and a control unit for controlling the operation of the actuators to control the rotational position of the swinging drawbar. The control unit is in communication with the steering controller of the tractor for monitoring the rotational position and movement of the steering wheel. When the steering wheel is rotated clockwise to turn the tractor to the right, the actuators pivot the swinging drawbar proportionately to the right to increase the steering ability of the tractor pulling an implement. When the steering wheel is rotated counterclockwise to turn the tractor to the left, the actuators pivot the swinging drawbar proportionately to the left.
