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.

First claim

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.
