The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A chisel nut for use in improving traction of a ground engaging drive element of a vehicle includes a body having a first end for engaging the ground engaging drive element and a second end disposed opposite the first end. A chisel face is defined on a side of the body spaced a distance from the first end and extending to an edge at the second end of the body. The chisel face sized and configured to extend outward from the ground engaging drive element beyond lug members of the ground engaging drive element. A hole is defined in the body about a longitudinal axis and extends from an opening at the first end of the body toward the second end of the body. The hole includes a threaded portion for threadingly engaging with a threaded portion of a cooperatively sized fastener positioned in the hole.

A track assembly for a terrain going vehicles having tires, the track assembly having at least two traction bars. The traction bars each having a body that is dimensioned to extend over the width of a tire and guide plates extending from the body so that they can be set to reach over the edge of the tire and to the sides of the tires and ears at each end of each traction bar, extending crosswise on relation to the length of the traction bar and on both sides of the body of the traction bar, the ears having each at least one hole. There is at least one link having a link body with a length and one connecting hole at each opposite end of the link body, and pins set to run through a pair of one hole of the link body and at least one hole of a ear of the traction bar in order to form a chain, wherein the pins are locked in relation to the holes of the ears so that rotation of the pins in the holes is prevented.

An endless track for propelling a snowmobile. The endless track includes an inner drive surface and an outer ground-engaging surface opposite to the inner drive surface. A first side surface is opposite to a second side surface. A plurality of first side lugs are adjacent to the first side surface. A plurality of second side lugs are adjacent to the second side surface. The plurality of first side lugs and the plurality of second side lugs provide traction when the snowmobile is operated off-axis and tilted on its side as well as provides traction surfaces on additional planes other than the outer carcass of the endless track when the track is submerged in the snow.

A snow groomer with touch screen controls for tensioning tracks, suspension, drive unit, accessories and other, comprising: a plurality of tracks; at least one accessory device selected in a group comprising a shovel or blade, a tiller assembly and a winch assembly; and a user interface comprising a display and a selector device for receiving commands from an operator, preferably the selector device is a device that detects a touch of an operator on the display; a control unit coupled to the user interface, in particular to the display, for sending images to be displayed to the display and receiving commands from the display which are related to the touches detected; wherein the control unit is configured to display on the display a main screen divided into a plurality of main screen portions, wherein the plurality of main screen portions are displayed together in the main screen and each in a different position in the main screen; wherein each main screen portion is configured to display an image that illustrates one or more pieces of data and/or information correlated to the tracked vehicle; the control unit is configured to detect one or more selections made by an operator, preferably on the display by means of a touch, corresponding to the type(s) of data or information that are required to be displayed in each portion of the display, and to display a main screen portion in each portion of the display, wherein each main screen portion is configured to illustrate a respective image relating to the data or information selected by the operator for said portion of the display.

A cross-link for tracks of snow groomers, the cross-link comprising a section bar, which has an elongated shape, extends in a first direction, is limited by an outer surface and comprises a portion for fixing to at least one belt of a track of a snow groomer, and it is provided with an inner cavity, which extends through the section bar in the first direction, and is open at the side in the first direction; wherein the inner cavity is filled, at least in part, with a filling material comprising metal foam, and in certain embodiments, the inner cavity is completely filled with the filling material.

The present invention relates to a ground engaging device (G) for an endless track (E) of a tracked vehicle. The ground engaging device is attachable to the outer side of said endless track (E).
