Abstract
A steering arm return to neutral mechanism for a steering arm pivotable on a shaft between a forward drive position and a reverse drive position. A torsion spring around the shaft has a first leg providing a spring force against a pin extending from the steering arm to pivot the steering arm from the forward drive position back to a neutral position, and a second leg providing a spring force against the pin to pivot the steering arm from the reverse drive position back to the neutral position. A stationary plate is positioned between the first leg and the second leg of the torsion spring.
Claims3
A steering arm return to neutral mechanism, comprising:
- a steering arm pivotable between a forward drive position and a reverse drive position;
- a torsion spring providing a spring force pushing the steering arm from a forward drive position and a reverse drive position toward a neutral position;
- the torsion spring having a coil, a first leg and a second leg;
- a pivoting pin and a stationary plate between the pair of legs of the torsion spring, the pivoting pin extending laterally outward from a lower end of the steering arm and contacting and moving the first and second legs to load the torsion spring;
- and
- a bushing rotatably mounted on the pivoting pin.
