UNLOCKED - Press the bottom of the switch in order to deactivate the transmission neutral lock.

Note: If the transmission neutral lock has been activated, you must shift the direction control lever into the NEUTRAL position before you shift the direction control lever into the FORWARD position. If the transmission neutral lock has been activated, you must shift the direction control lever into the NEUTRAL position before you shift the direction control lever into the REVERSE position. The direction control lever must be shifted into the NEUTRAL position in order to allow movement of the machine.

Note: When you exit the machine push the top of the transmission neutral lock switch in order to prevent the machine from moving out of the NEUTRAL position. Engage the parking brake in order to prevent machine movement when the transmission is in neutral. Refer to the Operation and Maintenance Manual, "Transport Positions".
