181 Automatic Steering System For An Agricultural Implement US12328378 2008-12-04 US20090272551A1 2009-11-05 Dennis Thompson; Terry Friggstad
An assembly for facilitating steering of an agricultural implement linkable to a work vehicle is disclosed. The assembly comprises at least a first ground-engaging wheel to engage a ground surface below a frame of the agricultural implement to support the frame above the ground surface. The assembly further comprises a positioning system for receiving a positioning signal from a positioning source. The positioning system determines a current position of the agricultural implement from at least the positioning signal, and the positioning system generates a control signal derived from the current position of the agricultural implement. The assembly further comprises a steering cylinder connected to the first ground-engaging wheel. The steering cylinder operatively connects to the positioning system to steer the first ground-engaging wheel based on the control signal.
182 Steerable machinery trailer US09118522 1998-07-17 US06179315B2 2001-01-30 Cale N. Boriack
A steerable machinery trailer (1) has a chassis (2, 33, 35, 36) intermediate a pivotal towing attachment (26, 29, 30, 46) and trailer wheels (3) proximate a rear portion of the chassis. The trailer wheels have pivotal attachment to the trailer and are pivotal for steering with a steering shaft (4) that is length-controllable intermediate rigid positioning on the chassis and a steering arm (6) attached to a steering rod (7) that is connected to a pivotal attachment of the trailer wheels to the chassis. Separately and optionally from being pivotal on the pivotal towing attachment by wheel-following of the trailer wheels, the chassis is pivotal on the pivotal towing attachment with a positioning shaft (8) that is length controllable intermediate rigid positioning on the chassis and a rigid lateral attachment (5, 9) to the towing vehicle. Length changes of the steering shaft steer the trailer wheels to guide the rear portion of the trailer from-side-to-side for selective turn-positioning of the trailer wheels. Length changes of the positioning shaft position the trailer laterally from-side-to-side for selectively side-towing of the trailer. Length changes of the steering shaft and the positioning shaft are controllable from a remote position with hydraulic-cylinder motors (39), electrical motors (41) and/or mechanical linkages.
183 Three-point hitch guidance control US803546 1991-12-09 US5246077A 1993-09-21 Larry E. Tjaden; Leonard E. Tjaden
A horizontal guidance control system for a standard three point tractor hitch is disclosed. The system employs the use of a manual control element which actuates a pair of hydraulic cylinders contained in a pair of hydraulic adjusters. The control element causes the extension of one cylinder and the retraction of the other cylinder, thereby causing controlled horizontal movement of a pair of pull links of the tractor hitch.
184 Cylindrical baler with automatic steering system US361948 1982-03-25 US4433533A 1984-02-28 Angel Giani
Tractor drawn baler for the formation of large diameter cylindrical or round bales. Baler comprises a bale-forming chamber into which the harvest products are fed through an opening by a pickup which removes the harvest products from a windrow. Detecting means such as pivoted arms with feeling rollers engaging the chamber circumference are provided along the length of the bale for detecting the lack of uniformity in the diameter of the latter. Steering means connected to the said detecting means for steering the baler by tansversely back and forth movement (zig-zag) relative to the windrow direct the harvest products toward the part of the bale that has the smallest diameter and thereby reestablishing the uniformity of diameter of the said bale.
185 Multi-unit adjustable plow system US617892 1975-09-29 US4049063A 1977-09-20 William John Dietrich
A plow system includes a number of individual plow units mounted on a beam which is inclined relative to the direction of travel of a traction vehicle. The units are mounted for continuous rotation about vertical axes so that they may be opened or closed to adjust the width of a cut between adjacent units over a continuous, wide range. The plow unit is supported by a forward furrow wheel located to ride in previously-plowed ground and a rear furrow wheel, and the main frame is pulled by a tongue or draft member connected between a tractor hitch and an intermediate location of the inclined beam. A hydraulic unit adjusts the individual plow units in unison, and at the same time, through a linkage, adjusts the tongue relative to the inclined beam to keep the forward furrow wheel at a constant distance from the rear tractor wheel for all width adjustments. A steering mechanism adjusts a steerable wheel, which may be the rear furrow wheel, to toe in such a manner as to offset the moment force on the system tending to rotate the system about the tractor hitch, and this offset or counter force caused by the toeing of the steerable wheel is adjusted to counteract the moment force which changes as the cutting width is varied. Further, the inclined beam is provided in modular form so that additional plow units may be added using standard parts or elements, as desired.
186 Disc tiller US3703932D 1970-08-31 US3703932A 1972-11-28 TUTTLE FLOYD W; TUTTLE RALPH W
A single-unit and a multiple-unit earth worker are provided. An elongated frame has earth-working members supported therebelow. A transversely disposed support member is centrally and pivotally attached to the rear end of the frame to pivot in a horizontal plane. The forward end of the frame has a pivotally mounted hitch, and a pivotally mounted wheel. The rear support member has a caster wheel mounted on each end. A first link connects the rear support member and the forward wheel, the link restraining same in normal position and operable to horizontally angle the wheel. A second link connects the first link and is rigidly connected to the hitch. A restraining link connects the transverse support member at the rear and the frame to restrict the extent of pivotal movement of the frame about the transverse support member. Turning linkage connects the frame and the hitch member. In the multi-unit embodiment, a plurality of caster wheels is used, one on each end of the frame and on opposite sides thereof. Caster linkage is connected to the hitch and the end caster wheels, such being operable to position the caster wheels relative the frame. Angular linkage connects the hitch and the frame, with such operable to rotate the hitch to proper position in relation to the frame, and turning linkage connects the frame and the hitch. Numerous types of earth workers such as disc tillers are known in the prior art operable to be turned in either direction, to the right or left. However, these disc tillers are one normally operable to be pulled with the discs inclined in one direction and turn more easily in one direction than the other. Also, many of the prior art devices are adjustable for the depth of the cut by varying the height at the wheel supports; this is usually done by a hand adjustment.
