A system for enabling movement of a machine is provided. The system includes a support member provided on the machine. The support member is configured to be in a raised position or a lowered position relative to a frame of the machine. The system also includes an actuation module configured to selectively enable the movement of the machine. The system further includes an enabler valve coupled to the actuation module and the support member. The enabler valve is configured to selectively send a pilot signal to the actuation module based on the position of the support member.
