Abstract
A crawler vehicle rides on four spaced-apart crawler track assemblies which extend lengthwise beneath the vehicle body. Ground pressure is reduced and traction, flotation and stability are enhanced by a suspension system which enables the forward portion of each track assembly to rise and fall independently of the others to accommodate to irregular terrain. For similar purposes, the suspension system enables the outer and inner track assemblies below the right portion of the vehicle to oscillate outward and inward as a unit about an axis extending lengthwise of the vehicle while enabling the outer and inner track assemblies below the left side of the vehicle to oscillate as a unit in a similar but independent manner.
