    Abstract: A speed reduction drive is used with a crawler track that is an endless member mounted on suitable supports including a ground engaging portion for moving a vehicle attached to a track frame. The speed reduction drive comprises a drive case having an input shaft and an output shaft. The output shaft has a pair of track drive wheel sections mounted on opposite ends thereof that protrude out from the drive case. The input shaft has a sprocket drivably mounted thereon and carrying a chain that drives a sprocket on the drive shaft. The input shaft is driven with a hydraulic motor and has a normally spring-applied pressure released brake on the input shaft. The track drive wheel sections have bars or drive elements that engage lugs on the track to effect the driving arrangement when the track drive wheel sections are rotated.

    Abstract: 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.

    Abstract: 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.

    Abstract: Power machines, control systems and methods are disclosed that automatically control engine speed and travel speed, in two different modes of operation. In a first mode of operation, both of engine speed and travel speed are controlled responsive to actuation of a foot throttle. In a second mode of operation, the foot throttle controls travel speed, but engine speed is controlled by a hand throttle. Selection of which of the first and second modes to utilize is based upon an actuation position of the hand throttle.
