Abstract

Improvements are made to prior tractors supported and driven by a rubber track (62) having bogie wheels (61) to increase the boom lifting capacity. The improvements include a main subframe having a loop-like structure which has a center section (74) extending under the tractor frame (70,72) midway between the front idler wheels (63) and rear drive wheels (65), two end sections (76,80) extending outwardly, one end section (76) supporting the drawworks (78) and the other end (80) supporting the tairlead (82). A rigid cross member extends from the fairlead (82) to the drawworks (78) and is positioned above the tractor frame (70,72) beneath the cab (106).
