A strong, light-weight track shoe for use with a track-laying vehicle. The shoe includes a cast body portion having three bored lug segments spaced along the front of the shoe and a pair of bored lug segments spaced along the rear of the shoe. The cast body portion has a fin-like guide member for engagement with sprocket and bogey wheels. Pairs of reinforcing ribs extend lengthwise along the shoe which form the longitudinal sides of sprocket tooth engaging openings. A single grouser extends along the width of the shoe to reinforce the body portion and to provide traction between the shoe and ground as the vehicle moves along a terrain. The grouser member and the rear lugs form the leading sides and the trailing sides of the sprocket tooth openings, respectively.

A one piece cast track shoe having a flat body portion (31) formed with three front and two rear laterally spaced apart apertured pivot pin and bushing receiving lug segments (36, 42), the two rear lug segments symmetrically spaced apart on opposite sides of a median line passing lengthwise through the track shoe for interweaving between three front lug segments on an identical track shoe for constructing an endless crawler track, the flat body portion formed with a lengthwise fin-like guide member (53) on the median line for guiding sprocket and bogey wheels over the flat body portion, the guide member positioned over the middle front lug segment of the three front lug segments when the track shoe is in a ground engaging position, a grouser member (52) formed on a ground contacting side (60) of the track shoe and extending laterally and positioned rearwardly of the three front lugs and below the guide member when the track shoe is in the ground engaging position, pairs of laterally spaced reinforcing ribs symmetrically positioned on opposite sides of the median line and forming longitudinal sides of a pair of sprocket tooth receiving openings (30) in the flat body portion, the grouser member forming a leading side of the openings and the two rear lug segments forming a trailing side of the openings, a transverse reinforcing rib (61) extending across the lateral space between the two rear lug segments connecting the pairs of ribs at the trailing ends of the openings, the grouser member connecting the pairs of ribs at the leading ends of the openings, the grouser member together with the guide member and the middle front lug segment forming a solid cast mass, when the track shoe is in the ground engaging position extending upwardly into the guide member and rearwardly to the leading sides of the openings when the track shoe is in the ground engaging position, thereby reinforcing the flat body portion on lateral opposite sides of the guide member.
