  • Publication number: 20230124346
    Abstract: A tractive element for a power machine can include a frame, an endless track, a drive sprocket, and a first set of split rollers. The first set of rollers can include a first roller rotatably coupled to the first plate with a first axis of rotation and a second roller rotatably coupled to the second plate with a second axis of rotation. The first axis of rotation and the second axis of rotation can be spaced apart from one another with a first roller offset distance, along a front-to-back direction of the tractive element, that can provide improved ride quality.

  • Publication number: 20220242501
    Abstract: A kit and corresponding method can be used to convert wheels of a power machine to track assemblies, such as to convert a four-wheeled power machine to a quad track power machine. A stub shaft (346) can be secured to an axle (328) of a power machine (300) and can be configured to support a track frame (366) of a track assembly in place of a wheel (319). A bearing (368) can be secured to the stub shaft (346) and a bushing (376) can engage the axle (328) to rotatably support the track assembly relative to the axle (328). Pieces of a segmented sprocket (378, 380) can be separately secured to a hub (306) of a power machine (300) to help install and drive a track of a track assembly.

  • Patent number: 11255070
    Abstract: Disclosed embodiments include power machines, implement coupling systems and methods in which hydraulic or electric coupling between an implement and the power machine is made automatically using an existing actuator, for example a tilt actuator, of the power machine. Thus, additional actuators are not required to achieve hydraulic or electric coupling. In exemplary embodiments, power coupling is also free from the process of mechanically coupling the implement to the implement carrier. Also, in exemplary embodiments, a machine side coupler assembly moves with the implement after a connection is established, despite the implement coupler assembly being removed from the implement carrier. This allows the same implement carrier to be used on all similarly sized machines.

  • Publication number: 20210270004
    Abstract: A power machine can include a frame, a lift arm, and one or more electrical devices for control of one or more work elements. An electrical tilt actuator can be secured to the lift arm to change an attitude of an implement carrier, an electrical lift actuator can be secured to the frame to raise and lower a lift arm, an electrical drive motor can be mounted to a track frame to move a track, or a battery assembly and electrical control module can be secured to the frame, including rearward of an operator station.
