Abstract: A surface grader mechanism that is attached to, and dragged behind, tractors or other towing vehicles. This implementation of such a surface grader includes a blade at the leading edge that may be adjusted to any height or any transverse, horizontal angle above the metal grating on the bottom of the surface grader.

Abstract: A reclaimer has a frame and a plurality of wheels connected to the frame. The reclaimer has a drum chamber connected to the frame and including movable door. The reclaimer has a milling drum positioned within the drum chamber. The milling drum engages with a ground surface. The reclaimer has an engine that rotates the milling drum and propels the wheels such that material exits the drum chamber from under the movable door. Further, the reclaimer has a controller that determines a position of the movable door based on at least one of a machine characteristic and a predetermined gradation for the material exiting from the drum chamber, and selectively adjusts an actuator associated with the movable door based on the determined position.

Abstract: A sulky for a self propelled lawn mower, the sulky being interconnected by a pivot frame and a horizontal pivot to the mower frame, and a parallelogram link structure to mount the seat to the sulky for automatic adjustment of the seat to lawn mower distance as the mower moves over uneven ground.

Abstract: A pulverizing machine with a cutter assembly adapted to be towed when the machine is moving either forward or in reverse. The machine includes a frame, a plurality of wheels supporting the frame, a cutter assembly carried by the frame and a pair of elevation cylinders for raising and lowering the cutter assembly. The cutter assembly has a cutter housing and a cutter drum rotatably mounted within the cutter housing. The cutter housing is pivotally suspended from the frame by a pair of chain cases, one on each side. Each chain case contains a chain drive assembly connected to the cutter drum to drive the rotation of the cutter drum. Cutter teeth extend from the cutter drum to pulverize material as the cutter drum is lowered and rotated into the material. A pair of rear cylinders are mounted between the rear of the cutter housing and the frame. When the machine is operated in the forward direction, the chain cases tow the cutter assembly.

Abstract: An apparatus for pulverizing a surface such as a road bed, parking lot, an interstate shoulder or the like. The apparatus comprises a frame with a cutting means secured thereto. A bidirectional drive and control means is also provided to enable the apparatus to make multiple passes over a surface while in an operating condition without turning the apparatus around. A system for adding liquid to the surface being pulverized may also be included.

Abstract: A control device for use in a dual function machine includes a first disconnecting device for connection between a first operator's control knob and at least one control valve usable for controlling a first function of the machine. A second disconnecting device is provided for connection between a second operator's control knob and at least one second control valve usable for controlling a second function of the machine. The disconnecting devices are arranged for mounting in actuating relationship to a swivel-type operator's seat, the first disconnecting device being actuated for disabling the second function when said seat is in a first position for operating the first function and the second disconnecting device being actuated for disabling the first function when the seat is in a second position for operating the second function.

Abstract: An implement supporting vehicle comprises an elongate implement support frame, along one side of which two drive units which propel the vehicle are mounted equidistance from the center of the vehicle. Two castor wheels are mounted along the other side of the frame. The drive units are moveable between a first working direction in which the vehicle can be propelled in a first direction transverse to the longitudinal extent of the frame and a second transport direction in which the vehicle can be propelled in a direction substantially perpendicular to the first direction. A moveable operators cabin is mounted with the frame.

Abstract: An agricultural tractor having at least four side-by-side pneumatic rear tires which provide a relatively narrow path of travel, there being a narrow rear portion of the tractor's body having about the same width or less as seen in plan as each of the tires and which is centrally disposed between the tires. A three-point lifting device extends rearwardly from the rear body portion. A front body portion carries an engine and the two body portions are pivotable relative to one another about a substantially vertical axis. An operator's seat and operating controls in a console are located within a cabin mounted above the rear wheels, the console being turnable through substantially 180.degree. about a substantially vertical axis so that the operator occupies a turnable seat which faces either generally forward or generally to the rear whereby the operator has a direct view of an implement attached to the lifting device.

Abstract: A tractor of acceptable width for highway travel having a narrow body portion between the front and rear wheels, such width being less than the width of each pneumatic tire mounted on the wheels. Four side-by-side rotatably mounted tires on each axle have narrow body portions disposed centrally and closely between them, such body portions having an articulated connection about a vertical axis at the after part of the front wheels with the forward body portion extending forward from the front wheels where it mounts the engine and fuel tanks in a body part which is substantially wider than the portions to the rear thereof. The engine powers the front wheels and a power transmitting linkage connects it with the rear wheels through the front and rear body portions which, with lateral projections, house a differentials and the necessary shaft bearings.

Abstract: This specification discloses a side-shift backhoe having a laterally movable slide supporting an operator's station which is slidable with respect to said slide in a direction parallel thereto. Spaced stop members are provided for engaging the station as the slide moves from side to side whereby the relative position of the slide with respect to the station may be changed in either direction. In an alternative form the operator's station is mounted on a frame supporting the slide and the slide is provided with stop members which engage a projection on the station to move the station relative to the slide.
