Finger protection device

A shield assembly for the front drive line of a mechanical front-wheel drive tractor includes a one-piece, non-telescoping shield which covers the full length of the drive line and its U-joints. The shield receives and is supported by a quill at its rear end and is supported and received by a ring at its front end. The ring has brackets for bolting to the tractor front axle housing. Covers prevent debris from entering the front end of the shield.

Tractor drive shaft shield assembly

A hitch control system includes a position control lever coupled to a transducer which produces desired position signals, a draft force sensor and a hitch position sensor. A push-button switch is mounted in the control lever housing. A signal processor stores selected values of the sensed draft force in response to actuation of the push-button switch. The signal processor generates position error signals from the desired position and sensed position signals, and generates a load error signal from the sensed draft force and the stored selected draft force values. The hitch is controlled as a function of these errors.
