Abstract: A track tensioning system configured to automatically adjust and maintain tension on an endless track used in a track assembly. Tension is applied to the track by pressure applied by one of the rollers included in the track assembly. The roller is movable relative to the other components of the track assembly using a linear actuator. Power is supplied to the linear actuator via a power source. The power source is configured to regulate the amount of power supplied to the linear actuator to maintain the track assembly at a desired track tension.

Abstract: A track frame with a tensioning system. The track frame has a first section, connected to a number of rollers, including a front roller, and a nested second section attached to a rear roller. The orientation of the first and second sections, and thus the tension on a track, is adjusted by a grease cylinder. The track frame has an indicator window, which displays the position of a plate indicative of tension on the track. When the plate is in alignment with the window, tension is appropriate. In addition, the position of the indicator window within a larger window in the first section is indicative of the stroke of the grease cylinder, which may indicate the need to replace the track.

Abstract: A vehicle having two configurations. The vehicle has two track frames, one on each side of a vehicle frame. The position of the track frames is adjustable relative to the vehicle frame by removing a connector, such as a first bolt, from a hole in the vehicle frame and a plate extending from the track frame. Another bolt is disposed in the vehicle frame and a slot in the plate. The track frame may be moved inwardly or outwardly to change the vehicle's configuration, and the first bolt reattached through the plate at a different hole in the vehicle frame.
