Abstract: Disclosed herein is a rotor control system for a rotary mixer including a set of extendable legs, a rotor having a set of extendable attachments, an operator control device, and a controller. The controller can generate control signals to cause return-to-cut operations to be performed.

In some implementations, the controller can be further configured to cause automatic return-to-cut operations to be performed in response to an operator interaction with a small set of controls sufficient to case the operation to be automatically performed.
