Abstract: A weight transfer linkage arrangement for connection between the three-point hitch of a tractor, a tool bar carrying agricultural implements and a hitch. The linkage arrangement includes a first parallel linkage connecting the tool bar and the hitch and a second parallel linkage connecting the three-point hitch of the tractor and the tool bar. The first and second linkages are both adaptable to be moved between corresponding cooperative lowered and raised positions, such that the tool bar may be raised and lowered without raising and lowering the hitch. Force applying means are connected to the first linkage to apply downpressure on the tool bar when the linkage arrangement is in a lowered position.

Abstract: A mounting arrangement for fertilizer coulters including a selective locking mechanism whereby, at the option of the operator, the coulter may be permitted to pivot about the coulter supporting shank or be locked in place.

Abstract: A mounting arrangement for a coulter and knife which are mounted on separate collars on a vertical shank with the knife movable in the same vertical plane as the coulter including a locking mechanism which connects the mounting collars of the knife and coulter to ensure conjoint rotation of the knife and coulter about the vertical shank.

Abstract: A liquid fertilizer applicator is provided, designed to be pulled by a motive power source, for use in a variety of soil and tillage conditions. It includes a disc-shaped coulter and an associated applicator knife mounted in trailing relation to the coulter, with a feed tube fixed to the rear of the knife. The leading edge of the arcuate knife conforms to and lies in close proximity to the outer periphery of the coulter disc. An alternative arrangement includes a knife with an angled lower facing edge and a heel extension to protect the feed tube opening.

Abstract: A clamp arrangement is provided for mounting an agricultural tool to a tool bar or cross bar. The clamp includes an upper clamp plate and a lower plate which are bolted to the bar and slotted to receive a vertical support bar. The vertical support bar is positioned vertically by means of a slotted clamp member which may be disposed above the upper clamp plate or below the lower clamp plate, the clamp member is fixed to the vertical bar by a set screw. Clearances are provided to absorb horizontal loads imposed on the agricultural implement.

Abstract: This invention relates to a folding tool bar assembly having a central tool bar structure and wing members hingedly mounted adjacent opposite ends thereof, with hinge mechanism pivotally connecting the respective wing members to the structure for movement between extended positions beyond the structure ends and folded positions overlying the central structure and including locking hooks to prevent relative movement of the central structure and wing members when in the operating position.

Abstract: An agricultural row marker assembly is provided which includes a three-piece articulated arm and which is hydraulically actuated. The assembly has a base which is connectable to an agricultural tool bar. A second arm is pivotally mounted to the first arm and a telescopingly extendable third arm is pivotally connected to the second arm. A marker disc is located at the distal end of the third arm. The arm is hydraulically actuated with the hydraulic cylinder acting on the first arm through a link member. A second link runs from the base to the second arm and a cable runs between the second link and the third arm so that extension of the hydraulic cylinders extendable rod urges all three arms in the substantially linear alignment.

Abstract: An earth working implement such as a field cultivator shank for use on a tool bar of a field cultivator includes a mounting bracket having an upper end and a lower end. The mounting bracket is secured at the lower end of the mounting bracket to the tool bar with the upper end of the mounting bracket extending rearwardly and upwardly of the tool bar. A spring shank is pivotably connected to the lower end of the mounting bracket at a first pivot point with the spring shank extending rearwardly and downwardly of the lower end of the mounting bracket. The spring shank terminates in a rounded end portion. A support bracket which securely engages an upper portion of the spring shank is pivotably connected to the mounting bracket and extends immediately beneath and alongside the spring shank for a portion of the spring shank length. A coil spring biases the spring shank downwardly away from the upper end of the mounting bracket.

Abstract: A silage unloader is disclosed for use in cutting silage from silage stored in a silage trench or the like. The unloader comprises a frame means which is adapted to be connected to the three-point hitch of a tractor or the like. A vertically disposed boom means is secured to the frame and extends upwardly therefrom and comprises telescopically mounted boom members. A reel boom is secured to the boom means and extends therefrom and has a silage cutting reel means rotatably mounted on the outer end thereof about a horizontal axis. A double acting hydraulic cylinder is provided within the boom means for raising and lowering the boom means, reel boom and reel. An auger conveyor means is provided on the frame means below the reel means so that the cut silage will be gathered thereby and conveyed to a blower means for blowing the silage to a feed wagon, truck or the like. The boom means, reel and conveyor are hydraulically powered while the blower means is powered by the tractor PTO.
