Abstract

A hedgetrimmer having a blade assembly that includes a sawblade for cutting through larger branches and other vegetative foliage. The blade assembly includes a reciprocating blade having an integrally formed sawblade portion that moves back and forth cutting motion. The other blade is fixed and includes a bevelled interior edge that helps debris being cut to pass over the blade and prevent getting stuck.

Claims

1. A vegetation cutting device, comprising:

a housing containing a motor;

a blade assembly extending out from the housing, the blade assembly having a support bar and a first and second blade for cutting vegetation, the first and second blade including cutting teeth forming a first configuration, the motor operatively connected to a first blade to move it in a reciprocal motion;

wherein the first blade has a sawblade portion secured to a distal end of the first blade;

wherein an interior edge of the second blade is bevelled.

2. The vegetation cutting device of claim 1, wherein the sawblade portion extends beyond the support bar.

3. The vegetation cutting device of claim 2, further including a bracket secured to the support bar to support vegetation as it'"'"'s being cut by the sawblade assembly.

4. The vegetation cutting device of claim 3, wherein the bracket is generally L-shaped, and includes a base portion that is secured within a U-shaped channel of the support bar, and a support arm that contacts the vegetation to be cut.

5. The vegetation cutting device of claim 1, further including a guard bar pivotally secured a distal end of the support bar, the guard bar being movable between a retracted position and an extended position where its tip extends beyond the blade assembly.

6. The vegetation cutting device of claim 1, wherein the cutting teeth having the first configuration extends beyond the support bar and face a first direction, and the sawblade portion faces a second direction opposite the first direction.

7. A hedgetrimmer having a sawblade, comprising:

a housing containing a motor;

a blade assembly extending out from the housing, the blade assembly having a support bar, a first blade having first cutting teeth and a second blade having second cutting teeth form a first teeth configuration for cutting vegetation, the motor operatively connected to a first blade to move it in a reciprocal motion;

a sawblade portion having cutting teeth of a second teeth configuration integrally formed at a distal end of the first blade; and

the second blade extending beyond the support bar and having an interior edge that is bevelled to help debris pass over the second blade.

8. The hedgetrimmer having a sawblade of claim 7, wherein the first cutting teeth and the second cutting teeth forming the first teeth configuration are opposite to the sawblade portion with the second teeth configuration.

9. The hedgetrimmer having a sawblade of claim 7, further comprising a bracket secured adjacent the sawblade to support any vegetation being cut by the sawblade.

10. The hedgetrimmer having a sawblade of claim 9, wherein the bracket is generally L-shaped.

11. The hedgetrimmer of claim 7, further comprising a guard bar pivotally secured to a distal end of the support bar, the guard bar being movable between a retracted position and an extended position where its tip extends beyond the blade assembly.
