Power management control for a power machine or vehicle is disclosed. In illustrated embodiments, a user interface of the power machine or vehicle includes a power management selection for activating and deactivating power management control. In illustrated embodiments, power management control is implemented through a power management control component based upon feedback from an RPM sensor. As disclosed in illustrative embodiments, the power management control component utilizes control methods and characteristics stored in system memory to determine control input to adjust hydrostatic parameters for power management.

Power machine or vehicle with power management

A vehicle having an auxiliary power system for supplying power to an implement is disclosed. The power system includes a power enablement device having an enablement component that allows or prevents supplying power to the implement, and an auxiliary actuator operably coupled to the power enablement device. The auxiliary actuator can be manipulated between a first, de-actuated position and a second, actuated position. An operator actuable continuous actuation device is moveable between engaged and disengaged positions, providing an actuation signal indicative of its position. A continuous enablement actuator is capable of engaging the enablement component when the enablement component is in the actuated position to discourage the enablement component from moving to the de-actuated position. The continuous enablement actuator engages the enablement component when the actuation signal indicates one of the engaged and disengaged positions and is disengaged from the enablement component when the actuation signal indicates the other position.

A two-stage latch is used for a tailgate on a vehicle such as an excavator or skid steer loader. The tailgate forms a cover for an engine compartment or other components of the vehicle, and the two-stage latch has a primary latch dog that will hold the cover fully closed. A secondary catch hook is used and includes a lost motion drive for actuating the latch dog. When opening the tailgate the latch hook engages a retainer bracket and will remain in a holding position so that the cover or tailgate will open slightly when the latch hook is released but cannot be fully opened until the catch hook is manually released from the retainer bracket on the vehicle frame.

The present invention provides a control apparatus for controlling movement of an implement. The implement is mounted to a subframe that in turn is joined to a frame portion of the vehicle. The subframe is moveable between the working position, where the implement is operable to perform work, and a second position. The implement has a hydraulic actuator for selectively moving a portion of the implement to perform work using controlled hydraulic fluid present in a hydraulic line connected to the hydraulic actuator. The control apparatus inhibits or allows hydraulic fluid flow in the hydraulic line as a function of the position of the subframe.

Swing lock for a backhoe

A backhoe or other similar earth working apparatus has a frame that mounts on a vehicle, such as a skid steer loader or tractor. A pair of stabilizer arms mounted to the frame member and pivotable along an arcuate path between raised and lowered positions, each have a stabilizer locking device. The stabilizer locking device comprises a hook member mounted on an exterior surface of an outer end of each stabilizer arm, and a latch member mounted to the frame member for releasably engaging each hook member such that when the hook member is engaged, the stabilizer arm is retained in the raised position.
