1. A system for controlling a traction lock system on a power machine with an engine configured to drive one or more tractive elements, the system comprising:
a brake configured to lock one or more tractive elements; and
a control system in communication with the engine and the brake, the control system including at least one processor device and at least one memory storing instructions executable by the at least one processor device, the instructions when executed by the control system causing operations that comprise:
receiving a brake input for activation of the brake;
in response to receiving the brake input, temporarily commanding the engine towards a predetermined engine speed that is less than an operating speed of the engine that corresponds to an operator-provided throttle command when the brake input is received; and
delaying engagement of the brake based on the brake input until after the engine is commanded towards the predetermined engine speed.
