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.

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.

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).

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.

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.
