Abstract

Machines, such as large tractors used in earthmoving, operate in a cycle of pushing forward and reversing to a starting point. The net performance of the machine is a function of the speed at which the reverse segment is performed. Generally, using the highest gear for reverse accomplishes the goal of the fastest return. However, some high slope grade conditions may result in higher speeds using lower gears. A combination of slope, track speed vs. drawbar pull, and track slip may be used to recommend a gear and track speed with the greatest ground speed for reverse operation.
