ABSTRACT:
An adjustment mechanism for snow deflectors is disclosed which is connected between a discharge chute and pivotal deflector to permit an operator to orient and secure the deflector at a desired angular position without leaving his station. The angular adjustment of the deflector is controlled by the operator pulling on a flexible cable which is connected at one end to the deflector. The adjustment mechanism includes a ratchet block which is pivotally secured at one of its ends to the chute and a shouldered pin which is fixed to the deflector. The shouldered pin extends into the ratchet block for locking engagement therewith. The deflector and ratchet block pivot in response to the operator pulling the flexible cable which permits the shouldered pin to engage a selected one of several locking teeth along a toothed slot in the ratchet block thereby securing the deflector at various selected angular deflecting positions. The shouldered pin and attached deflector are selectively movable along the toothed slot until the maximum angular deflecting position of the deflector is reached, at which point the ratchet block may be automatically disengaged from the shouldered pin and the deflector returned to its minimum angular deflecting position by a coil spring connected between the chute and deflector.
