Abstract: Support bearing to receive the ends of a crawler front traverse for fastening to the track roller frame, the bearing support comprising a pin with ball joint arranged in a completely sealed housing and forming a self-contained pre-fabricated unit which according to production requirements is fitted to the traverse or to the track frame prior to assembly. Joint allows axial movement to accommodate kinematics of support linkage.

Abstract: In a crawler vehicle having a rear housing or frame a splitter gearbox and double hydraulic pump for a hydrostatic transmission are mounted on the front flange of the rear housing for ease of servicing and plumbing. A single driveshaft from the engine drives the gearbox and an extra pump may be mounted on the splitter gearbox. The single driveshaft may constitute a power-take-off drive.

Abstract: A control arrangement for a pair of valves in which a control member is pivoted on the control lever of a first valve for movement normal to movement of first control lever. A link interconnects control member and U-shaped control lever of second valve so that movement of control member about pivot causes movement of second valve.

Abstract: A latching arrangement for complemental top and bottom door panels on a cab of a tractor includes a handle which is pivotally mounted to the top door panel between operative and inoperative positions. Biasing means in the form of a coil spring mounted between the handle member and the door normally urges the member to its inoperative position. An element connected to the lower door panel and defining a recess to receive the handle member operates to position the upper door in angular relationship to the complemental lower door member to ventilate the cab. A peripheral portion of the handle which is received in the connecting element is disposed at an angle relative to the axis about which the handle pivots to thereby define the angle at which the complemental door panels are held apart.

Abstract: Side shift backhoe clamped by two vertical acting and one horizontal clamp. Restrictors allow operation of vertical clamps prior to horizontal to prevent loading of slide rail. Vertical clamp actuators are secured in casting by L-shaped slots which allow actuator to be secured without bolts and allow vertical movement of actuators. Hook on casting takes longitudinal loads and resolves them partially to vertical loads.

Abstract: A mounting structure for detachably connecting a backhoe to the rear of a tractor comprising a unitary frame forming a vertical pivot for the backhoe and having attaching members located at the underside of the tractor to receive connecting elements all of which are disposed in a common horizontal plane and form the sole connection between the vehicle and backhoe.
