Abstract: A moldboard support is pivotally hinged to its carrier and has a medial rearward portion pivotally connected to a lower link, the upper portion of the link having an arcuate ramp with a portion engaging a detent mounted in an upper link that is pivotally connected to the lower link at its lower end portion and to the carrier at its upper end. The support and two links form a toggle in which the pivot pin connecting the two links is normally slightly rearward of a line connecting their upper and lower pivot pins and that permits the support to pivot rearwardly and upwardly when an obstruction is met and to return by gravity when the carrier is raised. The operating angular position of the support may be changed by shifting the pivot pin for the upper link.A tension spring is mounted to exert an initial resetting force on the moldboard support in its upper tripped position to assist in breaking away from impacting materials.

Abstract: A laterally yieldable or "bendable" hitch pole is provided for the steering mechanism of a trailing vehicle to minimize or prevent breakage of the hitch pole during sharp turns negotiated by the draft vehicle, especially during backing of the trailer. The invention is especially applicable to trailers having steering mechanisms of the Ackerman type. The hitch pole is typically swingable between right and left stops and breakage or other damage occurs when the pole encounters one or the other of the stops and turning forces are still applied. The invention provides a two-piece hitch pole having its end-to-end parts connected in such manner as to enable "bending" of the hitch pole in those situations with subsequent recovery of the pole to its normal attitude.

Abstract: An assembly for mounting the shank of a ground tool to a clamping plate carried on the tool bar of a soil tilling farm implement. The mounting assembly has a mounting member for attachment to the clamping plate, a first pivotal connection of the tool shank with the mounting member, and a variable pressure unit associated with the tool shank and the mounting member for applying a variably decreasing pressure on the ground tool during movement thereof from an operating position to an inoperative position. The pressure applied by the variable pressure unit, in a first moved position therefor, acts to initially hold the ground tool in the operating position, and in a second moved position being rendered ineffective to return the ground tool to the operating position.

Abstract: The present invention relates to a shank assembly for a soil undercutter, which is similar to an extremely wide cultivator shovel which travels underneath the ground and cuts the roots from weeds and plants without substantially disturbing the surface of the ground. The shank assembly position can be adjusted by changing the length of a link which holds the shank assembly in position. As shown the link includes a spring trip with a near center type toggle trip release that prevents "floating" and will hold the blade in position until an obstacle is encountered. The shank and spring mounting rod are pivotally mounted with respect to a common pivot, and when the blade encounters an obstruction the toggle linkage releases permitting the shank to pivot rearwardly and upwardly, while the toggle linkage compresses the spring. The trip will automatically reset after the blade clears the obstruction.

The other link is connected to a standard carrying the earthworking tool. A control arm connected to the pin and a control rod is operable to rotate the eccentric pin 91 to adjust the overall length of the toggle links.

Abstract: A fast clamp chisel trip apparatus is disclosed for use with a chisel plow having a frame with a tool attached thereto with means for lowering and raising the tool to positions for working and for transporting said plow, respectively. The embodiment of the apparatus disclosed includes means for holding the tool in a rigid position for plowing while the plow is in its work position, said means being adapted to remove the tool from this rigid position whenever the tool, while in the process of plowing, encounters any force of resistance greater than a predetermined force. Also included are means for setting said predetermined force into the apparatus, and means for returning the tool to its rigid position for plowing when the source of said resistance force has been by-passed.

Abstract: A down pressure control for use with furrow openers in grain drills which provides a spring load for maintaining down pressure on the furrow opener during normal operating conditions and which can be at relatively high rate to permit minimum tillage, or work in hard ground, but yet will release upon excessive movement of the furrow opener to prevent overstressing the hold down springs. The down pressure control is used in combination with an individual depth control for each of the furrow openers to insure that each furrow opener is individually controlled as to down pressure and depth.

Abstract: A beam for supporting an earth working tool, such as a moldboard plow, which is made so that it will float vertically over obstacles that do not hook the earth working tool, and which also includes linkage that will trip to provide clearance over obstacles which cause a high resistance to floating. The unit utilizes tension springs placed to insure reliable operation, and yet which provide high holding forces for working conditions. Folding links are used to provide full tripping of the mechanism. The folding links are arranged in relation to the provided tension springs to keep spring expansion to a minimum during tripping and yet permit reliable tripping under high forces. The springs provide adequate pressure for resetting after clearing the obstacle.

Abstract: A trip beam linkage for moldboard plow or other earth working tools which trips to clear obstacles such as rocks and the like and uses a sturdy, compact and reliable folding tripping linkage which permits reliable, high clearance tripping using tension springs. The linkage lengths are selected to permit reliance on a high spring force for initial holding, which is more reliable than over center or near center trip linkages. The folding linkage is positioned so spring expansion is kept to a minimum during tripping. The linkage can be adjusted to permit aligning the earth working tool. The working position of the linkage is determined by an adjustable stop.

Abstract: A resilient push dozer arrangement includes a push dozer transversely disposed at one end of a vehicle and a push arm rigidly secured to and extended from the dozer in juxtaposition to a longitudinally extending mounting frame of the vehicle. The distal end of the push arm is attached to the mounting frame through a device which permits limited longitudinal movement of the dozer relative to the mounting frame. An apparatus for cushioning the longitudinal movement of the push dozer toward the vehicle is provided so that the shock loads applied to the dozer are cushioned thereby and transmitted to the mounting frame at a point widely spaced from the attachment device.

Abstract: An automatic reset plow assembly includes a plow frame drawn by an agricultural vehicle. A plow standard is pivotally connected to the underside of the frame to enable the plow share to pivot backwardly and upwardly upon engaging an obstruction in the soil. The plow standard is resiliently biased downwardly by a toggle link assembly having one link pivotally connected to the plow standard and a second link pivoted to the frame. The other ends of the two links are pivotally connected together and to a slide element to form the elbow of the toggle link. The slide element is slideably received along a guide member which is also pivotally mounted to the frame. A compression spring surrounds the guide and resiliently biases the slide element and toggle links to maintain the plow standard in a normally downwardly pivoted plowing position. Upon encountering an obstruction, the plow pivots rearwardly and collapses the toggle link assembly.
