A device 1 for use with a continuous track 3 of a tracked vehicle to enhance the traction of the vehicle. The device 1 has an elongate body 5 having a ground contacting surface 6 and a releasable bracket 7 for releasably securing the elongate body 5 to the continuous track 3. The releasable bracket 7 has a bracket body 11, a first clamping member 13, a second clamping member 15 extending at an angle relative to the first clamping member, and a fastener 17. The bracket is arranged such that fastening the fastener 17 causes the second clamping member 15 to draw the first clamping member 13 towards the elongate body 5 to releasably secure the elongate body 5 to the continuous track 3. The device has one or more ground engaging features 39. A kit of parts is also described.

A combination as claimed in claim 10, wherein the track shoe further comprises an intermediate rib positioned between the two side ribs, and the elongate body nests between two side ribs of the track shoe and extends over the intermediate rib. 13. A combination as claimed in claim 10, wherein the elongate body extend across the transverse length of the track shoe, from one end of the track shoe to the other end of the track shoe. 14. A combination as claimed in claim 10, wherein the device is releasably secured to the continuous track. 15. A combination of a continuous track with at least one device as claimed in claim 1 secured to the track. 16. A device for use with a continuous track of a tracked vehicle to enhance the traction of the vehicle, the device comprising: an elongate body having a surface;a bracket arranged to secure the elongate body to the continuous track, the bracket comprising a ground engaging feature; anda plurality of rigid teeth operatively attached to the elongate body and projecting beyond the surface of the elongate body, the teeth being formed from a plate and each tooth having a generally chevron or inverted V-shaped ground engaging surface; wherein the elongate body and/or the teeth enhance traction of the vehicle in the running direction of the track and the ground engaging feature of the bracket enhances traction of the vehicle in a direction transverse to the running direction of the track, wherein the plurality of rigid teeth has a slot adapted to receive additional ground engaging features. 17. A device as claimed in claim 16, wherein each of the teeth has a generally flat and horizontal ground engaging surface, when viewed from an end of the elongate body. 18. A device as claimed in claim 16, wherein the device is releasably secured to the continuous track. 19. A device as claimed in claim 16, wherein the device comprises a releasable bracket for releasably securing the elongate body to the continuous track. 20. A device as claimed in claim 19, wherein the releasable bracket comprises a bracket body, a first clamping member extending from the bracket body, a second clamping member extending from the bracket body at an acute angle relative to the first clamping member, and a fastener, wherein the bracket is arranged such that fastening the fastener causes the bracket body to wedge the elongate body and the track shoe between the first clamping member and the second clamping member. 21. A device as claimed in claim 20, wherein the bracket body/bodies form ground engaging feature(s). 22. A device as claimed in claim 21, wherein a top surface of the bracket(s) is a substantially planar surface for contacting the ground surface. 23.
