  • Patent number: 6302378
    Abstract: A new snowmobile jack that does not require the hands or fingers of the user to be anywhere near the jack when raising and lowering the snowmobile. The jack comprises a T-bar that moves telescopically vertically to support a rear handle/tow bar on a snowmobile. A mechanical linkage operated by a first foot pedal raises and lowers the T-bar. A second mechanical device on the jack includes a positive latch operated by a second foot pedal. The latch positively prevents the first foot pedal and linkage from lowering the T-bar. Both foot pedals must be simultaneously depressed to release the latch and allow the T-bar to descend. The simultaneous action with two feet makes very unlikely any inadvertent lowering of the jack and obviates the need for the user to reach down to the jack with the hands.
