摘要： Disclosed embodiments include power machines and related structures of lift arms, implement carriers, follower links, and driver links which improve manufacturability, reduce component failures, and improve power machine design and functionality. In some embodiments, lift arm structures include cast lower lift arm portions. The cast lower lift arm portions include contoured upper ends which are sleeved onto contoured lower ends of upper lift arm portions to control stress points and to reduce stresses on welds. The follower link structures can include follower links which are configured to be positioned at least partially outside of the lift arm structure to improve rear visibility. The driver link structures can be configured to be laterally overlapping with innermost surfaces on the lift cylinder, but configured such that as the lift arm is raised the laterally overlapping portions are moved above the innermost surfaces of the lift cylinder.

摘要： A loader for a tractor includes a loader arm, a parking support, and a lock brace. The parking support includes a support pivot end pivotally coupled to the loader arm, a ground engagement end opposite the support pivot end, and a plurality of connection regions disposed between the support pivot end and the ground engagement end. At least one connection region of the plurality of connection regions includes an obstruction. The lock brace includes a brace pivot end pivotally coupled to the loader arm and an attachment end opposite the brace pivot end. The attachment end is made to removably couple to any of the connection regions. The obstruction obstructs coupling of the attachment end of the lock brace to the respective connection region of the parking support.

摘要： A remote angular position display system and method are disclosed. The angular position of a work implement of a work vehicle is displayed (e.g., textually, numerically or graphically) on a display associated with a portable device. The angular position is observed by a sensor coupled to the work implement or the work vehicle. The method includes receiving, by a processor of the portable device, one or more signals from the sensor indicative of an angular position value, and determining, by the processor, a condition associated with the work implement based on the angular position. The method includes outputting, by the processor, an interface for rendering on the display associated with the portable device that indicates the angular position and the determined condition associated with the work implement of the work vehicle.

摘要： A berm repair assembly repairs a berm adjacent to a roadway. The assembly includes a hitch configured for coupling to a vehicle. An elongated frame has a main section coupled to the hitch. A triangular first outer section of the frame is coupled to and extends from the main section of the frame terminating at a first end of the frame. The first end of the frame is positioned in laterally spaced relationship to the hitch. A leveler is coupled to the first outer section of the frame. The leveler has a substantially V-shaped medial section and a pair of spaced opposed side walls. Each side wall extends from an associated end of the medial section.

摘要： A tractor-mounted front loader includes a parking stand mounted to each of a pair of downwardly and forwardly inclined arm sections coupled to an implement resting on the ground. Each parking stand includes a support leg and a brace, the latter having a rear end pivotally mounted to a location approximately halfway between opposite ends of the support leg and an forward end pivotally mounted to a lower region of an associated loader arm section. The support leg and brace may be stored on the loader arm section by folding them together with a catch carried by the brace becoming releasably engaged with the support leg. The folded support leg and brace are then pivoted against the loader arm section and secured to it by a releasable latch which secures the top of the support leg to the arm section to establish a stored position.
