초록 ▼

A tractor having three sets of twin pneumatic tires mounted on wheels on each side of the tractor, a track being received around three, in one embodiment and two in the other of such pneumatic tires. In each embodiment only the rearmost set of wheels is powered directly from an axle rather than via the track. The track is a belt of flexible material which in the first embodiment has a plurality of traction members secured thereto by bolts extending through the belt and secured on the inner side by a strip opposite the traction members, such strip having a V-shaped portion which is received between the twin tires to retain the track in place. Each such traction member includes a part flush to the belt through which the bolts are received, a further part extending from the first part outwardly and normally to the belt and a ground engaging part extending from the second part in a direction parallel to the belt. The traction member in cross-section thus may alternately appear as an inverted U with outwardly extending flanges or as a “C”with square sides or as an inverted “T”or the like whereby, in other embodiments, the ground engaging portion of the traction member has at least one flange extending away from the second part of the traction member. In operation, the traction members tend to become biased when propelling the tractor under tension so their ground engaging parts are inclined downwardly relative to the ground from the tractor\s direction of travel.
