Patent number: 5363923Abstract: A carrier for a row follower is pivoted to the front of an agricultural tractor by a horizontal carrier pivot which is at right angles to the direction of travel of the tractor. This pivot permits the carrier to pivot away from the tractor in the event the tractor is reversed in direction of travel while the row follower is in the operating position. The row follower is connected to an encoder housing. The encoder housing is mounted upon an assembly pivot bolt so that it may be tilted to a carry position which raises to horizontal position, a shank which carries the row follower. The tilting of the encoder is accomplished by a solenoid which is primarily controlled from the cab of the tractor. The row follower shank is biased to be in a position aligned with the direction of travel. Also, the row follower shank is limited by the prongs of a fork to a maximum limited deviation from the alignment with the direction of travel so that it does not swing wildly.Type: GrantFiled: May 13, 1993Date of Patent: November 15, 1994Assignee: Gar Bar CorporationInventors: H.

Patent number: 5103924Abstract: A simple and inexpensive, mechanically coupled automatic guidance system for tractors comprising a ground line sensor which is directly coupled to a steering system comprising limited, partial, spatial disengagement or play about a narrow steering angle within which the automatic guidance system provides steering control, unencumbered by the forces of the primary steering system, especially the steering forces of a power-steered-tractor. The play in the steering system provides spatial relief of steering forces which could not otherwise be overridden by a purely mechanical system. The ground line sensor comprises three degrees of freedom permitting adjustable variation to the shape, breadth, and attitude of the sensor to conformably match a previously prepared ground line. At least two movement degrees of freedom allow the sensor to horizontally and vertically follow ground line and tractor path anomalies while providing feedback to the automatic guidance system.Type: GrantFiled: September 10, 1990Date of Patent: April 14, 1992Inventor: Dean B.
