Cat 163H
November 13, 2007

The Cat 163H motor grader uses a Cat 3176C DITA ATAAC with variable horsepower that matches torque curves to the gear for three operating modes: automatic, manual and off. The motor grader also has blade float that is incorporated into the blade-lift valves so the blade can move freely under its own weight. Its dual-certified air tanks supply braking capacity to each side of the machine, and it ensures secondary braking capability in the event a failure occurs in a single brake line. An optional hydraulic lockout mechanically locks all moldboard, machine and attachment control levers during machine roading.
