The user interface is actuatable between a forward configuration and a reverse configuration using a single hand.

Track assemblies (242; 300) for power machines (100; 200) include a track frame (243; 302), including a primary portion (304) and a second portion (306) moveable with respect to the primary portion. A plurality of rollers (248; 316) are positioned along the primary portion of the track frame relative to each other and the center of gravity of the power machine to provide an improved capability to compensate for vibration generated as the power machine moves over a support surface. In some aspects, a portion of a tensioning idler (e.g., 310) is positioned within a cylinder defined by one of the plurality of rollers.

An industrial truck extends along a longitudinal truck axis and comprises a drive section and a stand-on platform positioned on the drive section. The stand-on platform comprises a base element configured to pivot about a first pivot axis and a stand-on element mounted to the base element and configured to pivot about a second pivot axis. The first pivot axis is parallel to the second pivot axis and offset from the second pivot axis by an offset distance in a direction of a longitudinal truck axis, and the stand-on element is configured to extend above the base element to form a standing surface. A first suspension is configured to support the base element and a second suspension is configured to support the stand-on element. The first suspension is positioned at a distance from the second suspension in the direction of the longitudinal truck axis.

A working machine has a frame, a ground engaging propulsion system, a drive arrangement for providing motive power to the ground engaging propulsion system, an operator platform pivotally connected to the frame and moveable between a deployed position for supporting an operator thereon and a stowed position; and a sensor arrangement configured to sense when an external force is applied to the operator platform when said operator platform is in the deployed position. The machine prevents movement of the ground engaging propulsion system when the sensor arrangement does not sense an external force applied to the operator platform when said operator platform is in the deployed positon.
