The sprayer trailer has a trailer frame with a font end and a rear end. A pair of wheels are connected to the trailer frame. A hitch assembly includes a rear mast with a lower end connected to the trailer frame and a front mast with a front mast top end connected to a rear mast top end. A vertical guide assembly is mounted on the hitch assembly. A hitch connector assembly portion is mounted on a front mast lower end. A vertical guide assembly is mounted on the hitch assembly. A boom support frame is slidable on the vertical guide assembly. A sprayer boom center section is supported by the boom support frame. Nozzles on the boom center section move vertically between a lowered position below the rear mast and a raised position above the rear mast lower end.

The planer row unit has a unit frame with a front member that is adapted to be secured to a tool bar. A sub frame is secured to the front member by parallel links. A furrow opener disk, a seed shoe and a gauge wheel are secured to the subframe. A cam plate supported by a spring to the rear of the seed shoe presses seeds into moist soil in the bottom of a seed furrow. A seed covering disc is supported by a covering disc shank to the rear and to one side of the furrow opener. The covering disc has a circular plate portion that faces downwardly and forwardly, moves loose soil from the furrow opener into the seed furrow and rotates about a central axis that extends downwardly from a horizontal plane. A flange, with notches extends radially outward and rearwardly from the outer periphery of the circular plate portion, rolls and slides along the surface and limits soil penetration by the covering disk.

The toolbar (10) includes a center section (12), a first wing (14) and a second wing (16). The first wing (14) is pivotally attached to the center section (12) by a first wing pivot pin (132). A double acting hydraulic cylinder (154) for pivoting the first wing (14) relative to the center section (12) is pivotally attached to the center section and to a lift link (146) which is also attached to the first wing by a pin (148). The lift link (146) increases the range of movement of the first wing (14) relative to first wing pivot axis (138). A lift link lock latch bar (198) is pivoted about the axis of pendulum shaft (188) by a pendulum weight (194) and moved into a position in which movement of the lift link (146) relative to the first wing 14 is blocked. Retraction of the cylinder 154 moves the first wing (14) toward a transport position and the pendulum weight 194 pivots the lift link lock latch bar (198) away from the lift link (146) thereby freeing the first wing (14) to pivot to its transport position. The second wing (16) is attached to the center section (12) and folded in the same way as the first wing (14).

The row crop cultivator includes a cultivation unit (10) with a unit frame (12) attached to a tool bar (21) by parallel links (28 and 34). The unit frame (12) is supported by a pair of gauge wheels (14 and 16). A disk coulter (18) is mounted on the unit frame (12) with its forward edge positioned between the gauge wheels (14 and 16). A middleworker (20) is supported by the unit frame (20) directly behind the disk coulter (18). The gauge wheels (14 and 16) are mounted on an axle assembly (90) that includes gauge wheel arms (92 and 94) and a force equalizing link (98). The force equalizing link (98) equalizes the force exerted on the two gauge wheels (14 and 16) by the unit frame (12). An adjustment rod (106) adjusts the position of the force equalizing link. A coulter adjustment rod (54 ) with a lost motion connection adjusts the maximum depth of the disk coulter. The middleworker (20) includes a shank attachment bar (152), a triangular horizontal plate (164) with a subsoil point (160) and two reversible shares (170 and 172).

Earthworking tool point

An improved row crop cultivator for use in minimum tillage applications is described. A plurality of ganged cultivating units are mounted on a tool bar adapted to be towed behind a tractor vehicle. Each cultivating unit comprises a frame which is supported on a pair of spaced-apart gauge wheels. Also mounted on the frame for rotation within the gap between the gauge wheels is a disk-shaped coulter blade which is configured to cut through crop residue and weed debris as the material being cut is held against the ground surface by the gauge wheels. This arrangement tends to prevent improper cutting known as 'hair-pinning'. Trailing directly behind the coulter blade is a middleworker comprising a narrow width shank depending from the frame and having a weld point on its lower leading edge and wing-like share blades flaring rearwardly and outwardly at a predetermined angle from the lower end of the shank. The middleworker design reduces the tendency for slabs of earth to be thrown onto and thereby damaging growing row crops.

Row crop cultivator

An inter-row crop cultivator for use particularly in severe residue conditions such as in minimum tillage conservation applications is disclosed. A leading gauge wheel providing support and soil surface tracking is immediately trailed by two laterally displaced discs which cut away from the row. Aft of the two cutaway discs and directly to the rear of the gauge wheel is a stabilizing and cutting coulter which prevents side to side sway while cutting and reducing residue ahead of a sweep shank which directly trails the cutting coulter. By severing and dividing the residue, the cutting coulter permits the residue to flow over the sweep and around the shank. The shank is adapted to receive an anhydrous ammonia applicator and knife assembly which may be easily and securely mounted to the shank. A plurality of such inter-row crop cultivators may be mounted on a tool bar. A winged ridger/bedder may be either positioned in a non-use or storage position above the soil on the shank or slid down the shank to a use position in contact with the soil for forming the loosened soil and residue into parallel ridges over the newly formed rows in preparing a seed bed for later planting. Various selectively adjustable controls are provided for setting gauge wheel height, stabilizing and cutting coulter height, cutaway disc separation and height, the downward pressure applied to the working implements, and implement deflection cushion tension permitting implement deflection upon impact with an obstruction.

A guide and gauge wheel assembly for a tool bar row crop planter has an arm mounted on the tool bar and pair of wheels rotatably mounted on non-linear axles. The axles are selectively mounted on lateral sleeves and upwardly and outwardly inclined sleeves secured to the arm to position the wheels in a toe-out and camber position, or a side-by-side parallel position.

Gauge and guide wheel assembly

Ballast blocks are located within a tool bar of an agricultural implement to increase its weight. Modular blocks of concrete are inserted into the tool bars and held by end retainers. The blocks are provided with bevels and notches for cooperation with an extractor to simplify removal of blocks when this is desired.

The planter includes a number of forward tillage units each followed by an aligned planting unit. Both units are independently mounted by four-bar linkages to the planter frame. Each tillage unit includes a leading banded coulter followed by a pair of rolling row cleaning discs which are, in turn, followed by a fluted coulter. The system may be used in any of the following planting modes: (1) no-till planting, in which the fluted coulter only is used to prepare a narrow band of soil for planting with no trash removal; (2) ridge planting or till-planting, in which the row cleaning discs clear a deeper wide band before the fluted coulter while leaving bands between the row crops untilled; (3) minimum tillage planting, in which the row cleaning discs may be used to clear a shallow band of surface trash before the fluted coulter; and (4) conventional planting, in which the tillage units are raised and not used. Simple field adjustment can quickly convert the system to any of these plow modes as field conditions require. In each of the first three modes, an adjustable weight may be used to set the weight on the tillage units.

A manually operable position lock for a hydraulic actuator (10) adding a cylinder (20) and a piston rod (22) with a stop finger (61) for actuating a push rod (60) to close a valve (32) and prevent fluid egress from the cylinder. The lock includes a pivot bracket (110) carried by a push rod, a control lever (111) pivoted to the pivot bracket, a link (114) pivoted to the control lever and slidably receiving the push rod, and a helical spring (120) carried by the push rod and engaging one end of the link.
