Abstract
A lawn edger generates a forced air stream which is divided into two separate air paths, one path discharging a first forced air stream behind a cutting blade of the edger to direct clippings generated by the cutter blade away from the edger and the underlying surface and a second path in which a second forced air stream is discharged in front of the cutter blade to clear the surface over which the edger is moved of debris. In an alternate embodiment, exhaust gasses from the drive motor are directed by a conduit into the two separate air paths.
Claims11
An edger comprising:
- a wheeled frame movable in a first operating direction over a surface;
- drive means mounted on the frame and having a rotatable drive shaft;
- a cutter blade rotatably mounted on the frame for rotation about an axis transverse to the first direction of movement of the frame;
- means for coupling the drive shaft of the drive means to the cutter blade for rotating the cutter blade;
- means, coupled to the drive means, for generating a forced air stream;
- and
- means, mounted on the frame and disposed in fluid flow communication with the air stream generating means, for directing the air stream into a first flow path located rearward of and projecting transversely outward from the cutter blade, and in a second flow path generally in the first direction of movement of the frame forwardly of the cutter blade.
