Abstract: A ground working implement comprises a frame for receiving working tools and a trailer tower on one side of the ground working implement for attaching the ground working implement to a vehicle. An auxiliary chassis arranged on an other side of the ground working implement with at least one wheel arm and a wheel rotatably fastened thereto. The at least one wheel arm is movable vertically with respect to the ground working implement via at least one linkage. At least one energy accumulator is arranged movably between the frame and the at least one wheel arm with at least one bearing, wherein the at least one bearing is arranged on a straight line. The at least one linkage is arranged in a lowered position and a raised position of the at least one wheel arm along the straight line.

Abstract: A ground groomer configured for roping simulators is disclosed. Example embodiments include: a generally horizontal main support member; an attachment pin coupled generally orthogonally to the main support member, the attachment pin being configured for attachment to a ski of a roping simulator; and a plurality of tines arranged to protrude through a lower surface of the main support member to scarify soil behind the skis of the roping simulator.

Abstract: A combination fertilizer and seeding Implement includes a front section of disk type fertilizer openers and a rear section of frame mounted seed openers. The fertilizer openers are connected by drawbars to a rockshaft which is vertically adjustable to accommodate different ranges of operating depths of the frame mounted tools. Shank depth is set by frame height, and the vertical adjustability of the rockshaft facilitates a wide range of frame operating heights for different tool depths while maintaining optimum disk opener drawbar angles.

Abstract: A agricultural implement incorporates a frame which is adapted to engage a three point hitch of a tractor. The frame employs a longitudinally extending member which is pivotally connected to a link member. A resilient yielding assembly is disposed between the longitudinally extending member and the link member to absorb forces exerted from the link member onto the longitudinally extended member. Accordingly, when the link is acted upon by forces which cause the link to exert a stress on the three point hitch of a tractor, the resilient yielding assembly allows the first link to pivot about the longitudinal member thereby reducing compressive loads exerted on the upper link of the tractor's three point hitch.

Abstract: Individual tool bars are mounted between upright guides of a horizontal rectangular frame. Rollers engaging the guides transmit longitudinal forces from the frame to the tool bars and allow the tool bars to move freely up and down. Ground working tools mounted to the bars can therefore "walk" over uneven terrain as controlled by balancing depth wheels and packer wheels. Hydraulic cylinders are mounted between the tool bars and frame for applying upward or downward force against the tool bars without inhibiting their free movement along the guides in response to ground contour.
