Abstract: An engine installation system includes two aftward members and two forward members. Each member is connected to a different bootstrap on one end and has a pivotable connection to a pylon on the other end. There is a link that connects one forward member with one aftward member, and another link that connects the other forward member with the other aftward member. There is a variable-length member connected to the bootstrap-end of each of the two aftward members, with each of the variable-length members having a pivotable connection to the pylon.

Abstract: A surface brake system for a detachable agricultural implement towed by a tow vehicle is provided. The detachable agricultural implement includes a frame connected by a telescoping tongue assembly at the tow vehicle. The frame and tongue assembly are movably supported by at least one wheel assembly having a circumferential tread surface. The brake system includes a pivot linkage pivotally connected at the frame of the detachable agricultural implement, and a horizontal aligned brake arm attached at the pivot linkage. The brake system further includes an actuator cylinder interconnected between the pivot linkage and the frame. Movement of the actuator cylinder causes the brake arm to engage a brake pad assembly against the outer circumferential tread surface of the wheel assembly so as to restrain movement of the wheel assembly and frame of the agricultural implement as the tow vehicle extends and retracts the telescoping tongue assembly.

Abstract: A scraper is provided for use on depth gauge wheels provided on planters for row crops such as corn, soybeans, cotton, beans, peanuts and the like. The scraper includes a scraper blade which is mounted at one end portion of an elongated arm for contacting the outer circumference of the depth gauge wheel and a second scraper blade that is mounted on the elongated arm at a position for preventing the accumulation of debris in the recessed well formed in the face of the depth gauge wheel. The other end of the arm is mounted by a bearing assembly to a hub provided on the depth gauge wheel. The bearing assembly is mounted coaxially with the axis of rotation of the wheel so that the arm remains stationary as the wheel rotates. In addition, the scraper blade remains in contact with the wheel as the wheel is moved in vertical and fore-and-aft directions.

Abstract: A discing tool is provided which includes a plurality of disc gangs connected to a movable elongated frame. The frame is supported on a number of rotatable wheel assemblies so that the disc gangs can be moved in a direction generally parallel to the longitudinal axis of the frame as well as in a direction generally perpendicular to the longitudinal axis of the frame. A pair of outer disc gangs are pivotally connected at their first ends to the center portion of the frame. The second ends of the outer disc gangs extend in opposite directions and the outer disc gangs can be positioned at various predetermined angles relative to the frame. A center disc gang is connected to the center portion of the frame and is vertically pivotal. When the discing tool is used to work the soil, the center disc gang disc harrows the section of soil between the first ends of the outer disc gangs.

Abstract: A horizontally folding implement has a pair of tool-supporting beams that project laterally outwardly from opposite sides of the central, fore-and-aft extending frame of the implement when the beams are in their widespread, working positions. A pair of vertical pivots on opposite sides of the longitudinal axis of the frame adapt the beams for horizontal swinging between such working position and a folded, transport position, while a pair of horizontal pivots adapt the beams for limited vertical swinging movement in order to accommodate variations in ground contour. A pivotal coupling between the proximal inner ends of the beams when the latter are in their working positions keeps the two inner ends at the same height relative to one another during terrain variations encountered by the ground wheels or the tools of the beams, but the coupling does not inhibit horizontal swinging of the beams between their working and transport positions.
