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 () can be secured to an axle () of a power machine () and can be configured to support a track frame () of a track assembly in place of a wheel (). A bearing () can be secured to the stub shaft () and a bushing () can engage the axle () to rotatably support the track assembly relative to the axle (). Pieces of a segmented sprocket () can be separately secured to a hub () of a power machine () to help install and drive a track of a track assembly.

Implementations of the present disclosure are generally directed to activating features in power machines. More particularly, implementations of the present disclosure are directed to remote activation of features in power machines. Implementations include, methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transmitting a request for an initialization indicator for a software package from an initialization system of a power machine comprising hardware physically capable of executing at least one function, the request being transmitted, by a communication link of the initialization system, from a machine controller of the initialization system to a remote system, communicating, by the communication link, the initialization indicator from the remote system to the machine controller, and in response to receiving the initialization indicator: storing, by the machine controller, the initialization indicator, and executing, by the machine controller, the software package to control the at least one function.

Remote feature activation in power machines

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.

Electrically powered power machine

Power machines and loaders having doors with an integrated display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., that allows the operator of the machine to see the displayed information closer to the line of sight with the work area. The display can show augmented reality information about a worksite.

Display integrated into door

Disclosed embodiments are directed to quad track skid-steer loaders and power machines having a frame, a cab, and a lift arm assembly pivotally coupled to the frame rearward of at least a portion of the cab and extending forward of the frame. A first axle assembly and a second axle assembly on a first side of the frame mount first and second track assemblies. A third axle assembly and a fourth axle assembly on a second side of the frame mount third and fourth track assemblies. A first drive motor rotates the first and second axles to drive the first and second track assemblies and a second drive motor rotates the third and fourth axles to drive the third and fourth track assemblies.

Quad track skid-steer loader

Disclosed embodiments include power machines having doors with a display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., allowing the operator of the machine to see the displayed information closer to the line of sight with the work area.

A grain spreading device for evenly distribute grain as it is poured into a storage bin. The grain spreading device generally includes a flow-control ring (e.g., an evenflow ring) adapted to be positioned below a grain bin opening, the flow-control ring comprising an upper opening and a bottom, and a cone movably suspended below the flow-control ring by a plurality of springs to create a variable opening between the cone and the bottom of the flow-control ring, the plurality of springs creating a restoring force, wherein the variable opening increases in size when a weight of grain on the cone moves the cone away from the bottom of the flow-control ring against the restoring force of the plurality of springs.

Grain spreading device

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.
