ABSTRACT:
An edger is provided with a rotatable cutting blade for trimming grass, weeds, and the like, wherein the angular orientation of the cutting blade is quickly and easily adjusted to a selected one of several cutting positions. The cutting blade is driven by a motor mounted within a motor housing which is in turn supported for rotation about a longitudinal axis between a front wheel assembly and a rear wheel assembly. A locking mechanism carried by the motor housing has a pair of spring-biased lugs normally received into locking recesses in the front and rear wheel assemblies to lock the motor housing at a selected rotational position and thereby lock the cutting blade at a selected angular orientation. The locking mechanism is manually retractable to withdraw the lugs simultaneously from their respective locking recesses to permit rotation of the motor housing simultaneously with respect to the front and rear wheel assemblies to alter the angular orientation of the cutting blade. In addition, the front wheel assembly includes at least one front wheel carried at the distal end of a pivot arm supported for pivoting movement about a transverse axis to adjust the vertical position of the wheel and thereby adjust the elevation of the cutting blade. A spring-loaded locking disk normally engages one side of the pivot arm to prevent wheel elevation adjustment and is retractable manually to permit wheel elevation adjustment.
