Quick answer<\/span>

What is the difference between an excavator travel motor and final drive?<\/h2><\/div>\n

The travel motor<\/strong> is the hydraulic component that converts hydraulic oil flow and pressure into rotary motion. The final drive<\/strong> is the mechanical reduction gearbox that takes that rotation, reduces its speed and increases torque before the sprocket turns the track.<\/p>

John Deere excavator specifications describe axial-piston travel motors working with planetary gear reduction, which is the same basic relationship this guide explains. [1]<\/a><\/p>
