Abstract
A drive system for a pull-type swather or windrower in which a sensing device senses the side-draft of the swather under operating conditions. The sensing device indicates to a compensating device which is operable from the sensing device whether to increase, decrease or leave unchanged the rotational speed of drive wheels which are provided on the swather and powered by a power plant. The drive wheels act to keep the swather in an effective cutting position substantially transverse to the longitudinal axis of the tractor.
Claims11
A position compensating system to alter the side-draft of a pull-type implement pulled by a source of pull power, said system comprising:
- (a) a drive wheel for supporting the frame of said implement and adapted to drive said implement;
- (b) drive means connected to said drive wheel to drive said drive wheel;
- (c) at least two hitch members forming a part of a connection between said source of pull power and said implement, one of said hitch members being movable relative to the other of said hitch members;
- (d) a sensing mechanism mounted between said hitch members for sensing said relative movement of said hitch members;
- and
- (e) a compensating means to which said sensing means is connected and connected to said drive means and operable in response to said sensing mechanism for automatically varying the output of said drive means.
