Abstract
An improved front blade mounting arrangement for a tractor is disclosed which includes a blade assembly supported by a blade mount for pivoting movement of the blade assembly to change its working angle. A control arm extending from the blade mount to the control area of the tractor permits the operator to raise and lower the blade mount and blade assembly in unison. A self-actuating lock mechanism is provided for locking the blade assembly at the desired angle when the blade assembly and blade mount are in the lowered position, the lock mechanism including a pivotal lock bar which is substantially disengaged from the blade assembly when it is in the raised position so that the tractor operator may conveniently angularly reposition the blade assembly without leaving the operator's control area on the tractor.
