ABSTRACT:
A four track vehicle especially adapted for logging on steep slopes includes a running unit and an upper unit. The upper unit is articulated relative to the lower unit to maintain a center of gravity within the four tracked pods upon which the running unit is mounted. Sensing systems are utilized to alert the operator when the machine is in an anticipitated tipping condition. Moreover, a unique suspension system combining a torsion frame and swingable pod mounting arms are employed. The pods are locked in position when the vehicle is in an operating mode and are unlocked when the vehicle is in a travel mode.
