System and method for defining a zone of operation for a lift arm

Power machines such as excavators having a house that rotates about a vertical axis on an undercarriage are disclosed. In certain conditions, a control system on the excavator can limit rotational movement of the house and/or pivoting of a swing function on a lift arm to contain work performed by an implement to a predefined range or work area.. ... Clark Equipment Company

Utility whisker broom

A first work tool arm is rotatably attached to a frame or reference structure, a second work tool arm rotatably attached to the first work tool arm, and a work tool attached to an end of the second work tool arm. An actuator and a spring are each rotatably attached to the second work tool arm and configured such that separate movement of the first work tool arm relative to the frame or reference structure and movement of the second work tool arm and work tool relative to the first work tool arm are achieved with actuation of the actuator.. ... Clark Equipment Company

Seat belt

Disclosed seat belt assemblies or mechanisms include a seat belt guide which positions the seat belt for convenient ingress and egress by an operator, but in a position which reminds the operator to fasten the seat belt. The seat belt guide is configured to be stiffer in one direction of movement to maintain the metal tab of the seat belt at a raised position to one side of the operator seat, for example at a position adjacent to an operator joystick or control, but to allow the guide and the seat belt to be moved across the operator seat (and operator) for buckling.. ... Clark Equipment Company

Modular backscreen for implement

Disclosed embodiments include backscreens, backscreen accessories for implements of power machines, and implements including the same. In the backscreens or backscreen accessories, a first backscreen portion is attached to a frame of the implement, for example by welding. ... Clark Equipment Company

Variable engine speed control

Power machines, control systems and methods that adjust engine speed based upon actuation of user input controls that control other power machine functions such as travel functions and lift arm functions. By controlling engine speed at least partially in response to the user input devices controlling other machine functions, more optimal engine speeds can be achieved.. ... Clark Equipment Company

Excavator track tensioning

Power machines, power sources for power machines, and methods which provide a hydraulic signal from a hydraulic system, through the swivel joint or swivel, to control a tensioning cylinder coupled to the undercarriage without requiring a modification to the swivel. In exemplary embodiments, the same hydraulic signal provided to at least one other hydraulic component on the undercarriage to control another machine function is also provided to control one or more tensioning cylinders. ... Clark Equipment Company

Small loader

Disclosed are power machines with an operator seat proximal to the rear or back of the power machine, hand grip operator supports which can have user input devices positioned thereon, and foot supports configured to comfortably allow an operator to operate the power machine from both seated and standing positions.. . ... Clark Equipment Company

Tracked utility vehicle

Utility vehicle power machines with a frame, single left and right side tracks or tractive elements, a cab, a box supported toward the rear of the frame, and a lift arm supported toward the front of the frame. The utility vehicle power machines can have removable covers on a front of the frame, forward of the cab to provide access to various components.. ... Clark Equipment Company

Mechanical control linkage

A mechanical linkage between operator input devices and actuators including a junction having a first portion operably coupled to an operator input device and a second portion operably coupled to an actuator. The first and second portions of the junction are connected when a cab is in an operating position and disconnected when a cab is in a service position. ... Clark Equipment Company

Fuel recirculation method and valve

Fuel recirculation methods, fuel supply circuits and fuel recirculation valves for selectively mixing hot return fuel from a diesel engine with fuel from a tank before providing it to back to the engine. In exemplary disclosed embodiments of fuel recirculation valves, the valves are configured to selectively mix the fuel in a controlled manner using a temperature sensitive actuator within the valve such that, when the temperature of the fuel reaches a certain point, the valve restricts flow pathways to reduce heated fuel being mixed with fuel from the fuel tank, and eventually closes to prevent any heated fuel from being mixed and overheating the fuel provided to a fuel filter, a fuel pump and the engine. ... Clark Equipment Company

Remote fluid supply for an engine

A system includes a first diesel engine operable to drive a first device, a first def tank associated with the first engine and operable to provide def to the first diesel engine during operation, a second diesel engine operable to drive a second device, and a second def tank associated with the second engine and operable to provide def to the second diesel engine during operation. An external def tank is arranged to contain a quantity of def that is coupled to the first def tank and the second def tank and operable to selectively deliver def from the external def tank to each of the first def tank and the second def tank.. ... Clark Equipment Company

Condensate vaporization system

An air compressor system includes a compressor having an intake end and a discharge end, the compressor operable to draw in atmospheric air at the intake end and to discharge a flow of compressed air from the discharge end, the flow of compressed air including a flow of entrained water vapor and lubricant. The system further includes a separator operable to remove a portion of the entrained water vapor and lubricant from the flow of compressed air, the separator discharging a flow of dry compressed air and a flow of effluent which includes the separated water vapor and lubricant. ... Clark Equipment Company

Joystick controller for power machine

Joystick controllers having one or both of a reference bar and a throat plate. The reference bar substantially surrounds the joystick and is mounted to a control panel, and provides a hand rest surface for an operator while operating the joystick. ... Clark Equipment Company
