Abstract: A grade propulsion system provided herein includes: a propel pump; a brake system; an operator control configured to receive and transmit a propel command and a Hill Mode activation; and a controller electronically coupled to the propel pump, the brake system, and the operator control, the controller configured, after activation of the Hill Mode and the propel command, to transmit a propel current to the propel pump and disengage the brake system when the propel current is equal to or greater than a cracking current plus an offset current.
