发明名称 Transmission activating and neutralizing system
摘要 A system for activating and neutralizing a transmission of a work machine includes an electrical circuit having a latching relay. The transmission is shifted by electrical solenoids which are activated by electrical current through the latching relay. Current to the latching relay is provided from an electrical source through a parking brake switch. When the parking brake is applied, the switch is open and the latching relay is de-activated. If the transmission is left in a forward or reverse position when the parking brake is applied, the machine will not move when the parking brake is released because the latching relay is still de-activated. To activate the latching relay, the transmission shifting mechanism must be moved to neutral. The transmission can then be shifted into forward or reverse positions.
