Guidance system for tracklaying tractors
First Claim
1. A guidance system for a track laying tractor for maintaining said tractor at a pre-selected distance from a previously formed ground furrow said tractor having a track roller frame, a rear sprocket, and front idler comprising:
- (a) a rear mount frame attached to the rear outside portion of said track roller frame;
(b) a rear arm connected to said rear mount frame extending outwardly at substantially a right angle from said rear sprocket;
(c) a sight wheel mounted on said rear arm adapted for riding in said previously formed furrow at a selected fixed distance from said rear mount frame;
(d) a front frame attached to the front outside portion of said track roller frame;
(e) a front arm connected to said front mount frame extending outwardly from said tractor at substantially a right angle to said front idler;
(f) an extension arm slidably mounted coaxially on the distal end of said front arm;
(g) furrow following means mounted on the distal end of said extension arm adapted for staying within said previously formed furrow at said selected fixed distance;
(h) transmittal means mounted on said front arm for measuring, and transmitting the difference in distance of said furrow following means from said front mount frame as compared to said selected fixed distance of said rear sight wheel from said rear mount frame; and
(i) receiver means operatively connected to said transmittal means for indicating the relative distance of said furrow following means from said front mount frame, and said selected fixed distance of said sight wheel from said rear mount frame.

Abstract
A guidance system for a track laying tractor in which a furrow following device attached to the track frame senses the distance from the furrow to the tractor and signals the operator or the hydraulic steering system and consists briefly of a sight wheel mounted orthogonally to the rear sprocket, cone wheels mounted for transverse movement orthogonally to the front idler, a bar rigidly attached to the cone wheels and universally to the rear sight wheel mounting and transmittal means for transmitting the distance of the furrow to the tractor and receiver means for indicating the distance to the tractor operator.
