Abstract

A work machine may include an idler wheel, a drivable track engaged with the idler wheel, and an actuator configured to move the idler wheel to adjust the tension in the drivable track. A controller may actively instruct the actuator to adjust the tension in the drivable track based on the pressure in the actuator and variables associated with the drivable track and the work machine.
