ABSTRACT:
A discharge chute locking assembly for use on a discharge chute assembly of a snow throwing machine includes an outward extending receiving flange on a first component of the chute assembly and an outward extending chute mounting flange on a second component of the chute assembly. The chute mounting flange is configured to be positioned in an abutting relationship with the receiving flange and has at least one key hole and at least one recess and slot combination in registration with the at least one key hole. A locking lever locks the chute mounting flange to the receiving flange. The locking lever includes an elongate body having an inwardly extending ledge, a pivot end and a locking end. The pivot end has a pivot tab extending therefrom sized and shaped to fit through the key hole when the locking lever is in a first orientation and wherein pivot tab is prevented from fitting through the key hole when the locking lever is in a locked orientation. The locking lever also has a locking tab extending from the locking end of the body. When the locking lever is in the locked configuration, the locking tab is configured to be received in the recess such that the tooth engages the slot and the ledge engages the receiving flange to lock the mounting flange to the receiving flange.
