Abstract: An earthworking tool having a biased trip assembly for yieldably holding the tool in a ground working position, allowing the tool to move over an obstacle, and return the tool to its earthworking position. The trip assembly has a stationary hinge member mounted to a support and a movable hinge member pivoted to the stationary member. A split sleeve spring surrounding the stationary and movable hinge members biases the members and earthworking tool to a ground working position. A modified trip assembly has a pair of split ring springs surrounding a stationary hinge member and movable hinge member to bias the movable member and earthworking tool attached thereto to a ground working position. An arm connected to the movable member rotatably supports a rotary hoe wheel.

Abstract: A mounting/positioning apparatus for attaching an agricultural implement such as a reel unit or a rotary packer assembly to the frame of a tillage machine is disclosed. The apparatus includes two opposing end portions rigidly coupled together by means of a cross member with the agricultural implement rotationally mounted between the two opposing end portions. The two end portions are pivotally coupled to a first frame cross member to which is rigidly coupled one end of a second frame member extending rearwardly therefrom. The other end of the second frame member is flexibly coupled to the cross member by means of a longitudinally compressible spring providing for the vertical displacement of the rotating implement upon impact with an obstruction. Spring tension is adjustable for varying the downward force applied to the working implement with the second frame member incorporating shear pin protection for the implement against high impact forces applied thereto from contact with rocks and other obstructions.

Abstract: A minimum tillage rotary hoe includes a tool bar mounted transverse to the direction of field travel. Projecting rearwardly from the tool bar are a plurality of rotary hoe support arms each having a single, uniform diameter, multi-tined rotary hoe affixed to the end thereof. The rotary hoe members are staggered to define a forward row and a rear row of hoe members, each row defining generally a separate, single axis of rotation. The axes of the rows are separated by a distance less than the diameter of the rotary hoes but greater than about 0.8 the diameter of the rotary hoes. Separation is considered critical in order to render the hoes self-cleaning. Self-cleaning of field trash is effected by movement of adjacent hoes and more particularly the tines of adjacent hoes past one another to clean out the trash.

Abstract: A hoe that includes a transversely extending tool bar, a pivot shaft mounted on the rear and lower portion of the tool bar and extending parallel thereto, a plurality of support arms spaced along the tool bar and pivotally mounted on the shaft, each arm having a forward portion for engaging the tool bar and a rearward portion for rotatably supporting a hoe wheel, a spring extending between each arm and the tool bar to bias the hoe wheel downwardly with each arm forward portion providing a stop with the tool bar to dispose the hoe wheels in the same operative position, and each arm having a hub pivotally mounted on the pivot shaft and including preferably a plurality of elongated grooves extending parallel and adjacent the shaft the full length of the hub and a lower drain in communication with the grooves to remove soil moving between hub and shaft to free the arm and thus hoe wheel for movement by the spring.

Abstract: A rotary hoe implement includes upstanding spacer members for connection to a tool bar for drafting by a tractor. A rotary hoe supporting arm is pivotally connected to a lower end of the spacer member and an elongate adjustment rod extends from a rear end of the rotary hoe supporting arm to an upper end of the spacer member. A spring member is sleeved on the adjustment rod and cooperates with spring length adjusters on the rod to bias the rotary hoe downwardly into ground engagement and control the up and down movement thereof as the hoe travels over the earth surface. The rotary hoe implements are constructed or ganged together as units and are selectively mountable along the length of the tool bar for operator control.

Abstract: A set of four rotary hoes are evenly spaced apart laterally so that the distance between the tracks is two inches and the distance between the outside hoes is six inches. The assembly is pivoted about the center to ride over uneven ground. The front and back hoe are removable so that the other two hoes, which are widest apart, may be operated as a rotating shield. The mounting is attached to the tool bar of a tractor and spring biased downward.

Abstract: Closely spaced cultivating tools are mounted along a tool bar and each tool may be locked in a raised position relative to the ground or may be lowered into floating engagement with the ground during use of the implement. A small tool bar is mounted parallel to a larger tool bar and the cultivating tools are slidably clamped on the small tool bar. Improved mounting structure allows each cultivating tool to be mounted on the small tool bar without having to slide each cultivating tool onto or off of the tool bar from the ends of the tool bar and without having to disassemble the mounting structure. The tool bar assembly includes row indicia for indicating where the tools are to be located along the tool bar and which tools should engage the ground and which tools should be raised away from the ground for various cultivating operations on row crops. A tool angling mechanism allows selective adjustment of the angle to the line of draft of each tool without the use of wrenches or other hand tools.

Abstract: A multiple rotary hoe including individual hoe wheels mounted in front and rear rows with an individual support arm for each wheel and all of the support arms having a common axis mounted on a single pivot shaft for independent pivoting action in response to upward and downward movements of the hoe wheels with such movements counteracted by spring means exerting downward pressure on each support arm independently of all of the remaining arms.

Abstract: A machine for uniformly applying a pressure on a relatively flat surface includes a portable frame structure and at least one frame supporting roller rotatably mounted on an axle by a pair of spaced journal assemblies. Each journal assembly has an upright bracket member with a top end secured to the underside of the frame structure, and an upright guideway in which the body portion of a bearing member, for rotatably supporting one end of the roller axle, is guidably movable. Flanges laterally extended from opposite sides of each bearing body portion are positioned between an associated bracket member and adjacent side of the roller. Each flange is formed with a fulcrum portion that is in contact engagement with the adjacent side surface of an associated bracket member for pivotal movement of the bearing member in response to a lateral tilting movement of the roller.

Abstract: A plow having a main frame beam disposed in a diagonal direction with respect to the direction of travel and having a plurality of plow bottoms equally spaced along the diagonal beam, each bottom being vertically pivotally supported on the beam. A furrow wheel frame is carried on the rear of the beam to swing about a vertical axis. The plow bottoms and wheel frame are connected together and are power operated so that the plows may have their effective plowing width adjusted while at the same time positioning the furrow wheel frame. A hitch connection is carried on the forward end of the plow and is composed of a first part which is adapted for connection to a tractor and a second part which is rearward of the first part and adapted to shift with the plow frame. The two parts are connected by a vertical pivot to permit relative lateral swinging between the parts.

Abstract: A rotary hoe implement, having hoe support arms independent of adjacent hoe support arms, and a selectively adjustable means for varying the downward pressure exerted by the leaf spring biasing means acting on each support arm.
