  • Patent number: 5579851
    Abstract: A roller for a field implement includes projections formed on an outer surface thereof about a circumference of the roller. The projections form adjacent rows parallel to the axis of rotation. The projections of a first row are spaced-apart along a longitudinal length of the roller. The projections of the second row adjacent to the first row are spaced-apart along the longitudinal length of the roller wherein successive projections of the second row are disposed between successive projections of the first row. The projections of a third row adjacent the second row are spaced apart along the longitudinal length of the roller wherein successive projections of the third row are disposed between adjacent projections of the first and second rows. The projections of a fourth row are spaced-apart along the longitudinal length of the roller and are disposed between adjacent projections of the first and second rows not having the projections of the third row.

  • Patent number: 5551518
    Abstract: A tilt rate compensating implement system and method utilizes first hand second sensors for sensing the position of the rod end portion of first and second implement lift jacks. A controller calculates a tilt angle of the implement based on a difference in the amount of extension of the lift jacks. An inclinometer senses an angle of the frame relative to a predetermined plane and a tilt rate sensor senses the rate of change of the frame angle relative to said plane. A corrected frame angle based on signals from the inclinometer and tilt rate sensors is combined with the implement tilt angle to provide a corrected implement tilt angle. A display device displays the corrected implement tilt angle. The controller compares the corrected implement tilt angle to the desired implement tilt angle and actuates a fluid operated system to move a tilt jack in response to a difference between the desired and corrected implement tilt angles. The tilt angle control system is particularly suited for use on a bulldozer.

  • Patent number: 5524711
    Abstract: The present invention entails an agricultural implement for forming planting rows with a minimum of tillage. The implement of the present invention is designed to form a multiplicity of rows and accordingly includes a series of side-by-side row units. Each row unit includes a front colter, a ripper which follows the colter, a rotor tiller assembly disposed behind the ripper, a pair of laterally spaced soil confining panels extending between the ripper and the rotor tiller assembly, and a final following soil packer. Once the agricultural implement has traversed a certain area of the land, there is formed a multiplicity of planting rows with the area between the formed planting rows being untilled.

  • Patent number: 5511625
    Abstract: An improved soil leveling apparatus includes a hitch (202 or 302) for connecting the frame to the loader arms and tilt cylinder(s) of a skid steer loader. The hitch (302) includes a hitch plate (304) that can selectively be made rigid with the frame or can selectively be allowed to pivot fore-and-aft relative to the frame. This allows the operator to select the rigid orientation of the frame when it is desired to have the frame be rigid relative to the loader or to select the floating, pivotal orientation depending upon ground terrain and other factors.

  • Patent number: 5505268
    Abstract: An implement for preparing a field includes a ground engaging device that allows the implement to be pushed or pulled on the field. The ground engaging device includes a reversible roller with projections joined to an outer surface thereof to engage the ground. The projections do not extend along the complete length of the roller but rather a portion thereof thereby reducing the power necessary to rotate the roller. The implement includes reversible guards for keeping the disturbed ground in front of the roller.

  • Patent number: 5491913
    Abstract: A control system for the suction line relief valve of a hydraulic dredge is disclosed. The system includes a relief valve actuator which is hydraulically operated; a hydraulic pump powered by a motor; a directional valve; an energy storage device; and hydraulic lines connecting the hydraulic pump, the accumulator, and the relief valve actuator. The accumulator converts the hydraulic pressure in the hydraulic lines into potential energy which is used to generate hydraulic pressure if the pump fails or loses power. The pressure generated is enough for the operator to move the relief valve actuator which will reposition the relief valve to a desired position after pump failure.

  • Patent number: 5491915
    Abstract: A locking pin (100) for use captively retaining a tooth (14) on an adapter portion (12) of an excavating tooth and adapter assembly has a primary wedge member (110) with an integral spring (120) extending upward from the member's distal end (116). A first positive slop means (130) extends from the wedge member (110) while an opposing second positive stop means (122) extends from the integral spring (12). After insertion, the locking pin (100) prevents separation of tooth (14) from adapter portion (12) while the first and second positive stop means (130, 122) prevent accidental loss of the locking pin (100) from the assembly. To remove the locking pin, a force sufficient to separate the first positive stop means (130) from the pin (100) is exerted to drive the pin (100) from the assembly. In another embodiment, the integral spring extends from a lateral surface of the locking pin (700, 800).

  • Patent number: 5488996
    Abstract: An improved frame for a drawn agricultural implement, such as a planter, includes a central main frame which is extensible. As the main frame extends, the wing sections fold forwardly. When the wing sections fold to a predetermined position, positioning links act to pull the main wheel set, which is mounted to a carriage and supports the rear of the central main frame, forwardly so that the down load on the hitch is reduced. Conversely, during the unfold cycle, after the wing sections have unfolded to a predetermined position, as unfolding continues, the positioning links urge the carriage and main wheel set toward the rear of the main frame to the field use position. A hydraulic circuit for folding, unfolding and preparing the implement for transport is also disclosed.

  • Patent number: 5479726
    Abstract: A padding machine attachment for a vehicle is provided. When padding of a ditch for a pipeline or cable is required, the padding machine is removably attached in a position at one end of a conventional bucket loader, bulldozer, or other base machine or vehicle, whereby said attachment moves along the path of travel of the vehicle. As the vehicle moves the padding machine attachment along one side of the pipeline ditch, the padding machine attachment picks up at least a portion of a pile of excavated material placed parallel to and along the same side of the ditch and processes the excavated material into padding material for placement into the ditch for padding the pipeline or cable.
