Abstract: A work vehicle is formed from a plurality of ground-contacting motive elements, a chassis, an operator station, a switch, and a hydraulic manifold. The operator station has a joystick having a manually-actuable control element used to actuate the switch. The hydraulic manifold has a pair of primary hydraulic ports, first and second pairs of secondary hydraulic ports, and a control valve. The control valve is actuated by the switch and is adapted to allow pressurized hydraulic fluid to flow through a selected one of the first or second pair of secondary hydraulic ports. Each pair of secondary hydraulic ports fluidly communicates with a hydraulic actuator carried by a work attachment. By actuating the control element on the joystick, the operator can conveniently switch the hydraulic control of the joystick between different hydraulic operations on the attachment without leaving the operator's station.

Abstract: The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is “reclaimed” for use with a drilling system.

Abstract: FIG. 1 is a left side view of our microtrencher blade, the right side being a mirror image thereof.
FIG. 2 is a top front left side view thereof.
FIG. 3 is a back top right view thereof.
FIG. 4 is a front top right view thereof.
FIG. 5 is an edge view thereof.
FIG. 6 is an expanded fragmentary edge view of the blade as shown in the call-out of FIG. 5.
FIG. 7 is an expanded fragmentary left side view of a tooth as shown in the call-out location of FIG. 1.
FIG. 8 is a close up right side view thereof; and,
FIG. 9 is an expanded fragmentary view of the call-out location shown in FIG. 2.
The broken line elements are included for the purposes of illustrating portions of the microtrencher blade and form no part of the claimed design. The line indicated by alternating dot-dash is a boundary line, the interior of which does not form any part of the claimed design. FIGS. 1, 2 and 5 represent callout locations for the expanded fragmentary views shown therein, with the borders of the call-out locations shown by lines of alternating lengths. Lines included with thin weight and which do not extend to any adjacent line are provided to show contour.-

Abstract: A hydraulic control system for use with a work machine. The work machine has a platform which supports an operator. When the operator is not on the platform, the platform moves into a first position, causing a signal generator to send a signal to a controller. The controller is configured to limit the hydraulic flow to the ground drive motor when the platform is in the first position. The controller may directly reduce operation of the engine, or may adjust a valve which diverts a portion of hydraulic flow. The limitation may be overridden when desired by the operator.

Abstract: A vehicle having a long track or wheel-trail wheel combination on one side and a smaller ground engaging member, such as a short track or wheel on the other. The vehicle has a work attachment on one end of as frame, which is provided clearance on the side of the vehicle with the short track or wheel. A control system is provided to allow an operator to properly control a direction of the vehicle despite the fact that different forces may be required to operate the long track and the short track or wheel.

Abstract: A track assembly is formed from an endless track, an elongate guide member, a drive sprocket, and a plurality of track engaging rollers. The endless track has an inner surface having a plurality of parallel circumferential ridges. Formed between the circumferential ridges is a circumferential channel. The guide member is at least partially positioned and closely received within the circumferential channel. The track engaging rollers are arranged in a pair of parallel rows near an outer side of each circumferential ridge. During track rotation, the guide member remains closely received within the channel, and the rollers contact the outer side of the ridges to resist lateral movement of the track. Positioning of the guide member in the circumferential channel, with the rollers outside the ridges, laterally stabilizes the track thereby reducing the risk of the track slipping off the track assembly.
