A traction chain for a caterpillar chain of a tracked vehicle. The traction chain is equipped with an engagement member for a driving wheel, with track guide elements, which are provided to guide a running gear of the tracked vehicle in a track, on an inner side of the traction chain, running in a running direction of the traction chain, and with a multiplicity of attachment members, each of which is provided to attach a caterpillar cleat to an outer side of the traction chain and transversely in relation to the running direction of the traction chain. The traction chain is provided for use with a lateral chain running parallel therewith, the traction chain furthermore is formed partially from an elastic base material, into which at least one traction member is embedded, extending in a running direction of the traction chain.

Skiing equipment (1) is provided comprising a ski (2); a track (3) closed on itself and wound around the ski (2); a mover of the track (3) around the ski (2); a fastening group (4) for at least one binding (4a, 4b) defining together with the ski (2) a channel (4c) for the sliding of the track (3); and wherein the track (3) comprises a belt (31) wound longitudinally around the ski (2) and defining two ends (31a, 31b); and a hinge (32) constraining the ends (31a, 31b).

A tracked, amphibious vehicle, provides at least two, spaced, elongated pontoons disposed generally parallel to one another. A platform structure can be supported by and structurally connects the pontoons, the platform structure including a transom and a lowermost generally horizontally extending panel. A continuous, endless belt can encircle each pontoon engaging bogie wheels on the pontoon. A supplemental, marine drive assembly includes a hydraulic motor having a shaft with an axis, a propeller shaft having an axis, wherein the motor axis and propeller axis are aligned. A universal joint connects the hydraulic motor to the transom. A housing includes a sleeve that contains the propeller shaft.

A compact utility loader comprising a frame, an engine, a pair of loader arms, and an attachment secured to ends of the loader arms. The compact utility loader additionally includes a first track or wheel and a second track or wheel positioned on either side of the frame. The compact utility loader additionally comprises a control interface including a graphic display configured to present operational information to an operator. The graphic display is configured to present a login screen prompting the operator for a passcode. The engine is prevented from being started until a valid passcode is entered via the control interface.

A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve f(x)=4.641e.sup.0.34x. The value x represents a horizontal direction and the function f(x) represents a vertical direction.

A support structure for a track system is disclosed. The support structure has leading and trailing linkages which are pivotally connectable to a frame member of the track system through, respectively, leading and trailing pivots. The leading linkage is pivotally connected to the trailing linkage through an intermediate pivot. The support structure has at least one biasing assembly. Leading, intermediate and trailing support wheel assemblies are connected to the support structure, which is adapted to move such that when the leading support wheel assembly moves in a first direction, the intermediate support wheel assembly moves in a second direction, and the trailing support wheel assembly moves in the first direction. A track system having the support structure and a vehicle having the track system is also disclosed.
