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 blade and a second blade for cutting vegetation, the first and second blades including cutting teeth, the motor operatively connected to the first blade to move it in a reciprocal motion;

wherein the first blade has a sawblade portion on a distal end of the first blade; and

wherein the second blade has a portion free of cutting teeth and including a beveled edge extending in a longitudinal direction of the blade assembly, and wherein the beveled edge is adjacent the sawblade portion for assisting in helping cut debris pass over the blade assembly.

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 portion.

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 first blade cutting teeth extend beyond the support bar and face a first direction, and the sawblade portion faces a second direction opposite the first direction.

7. A hedgetrimmer, 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 a first set of cutting teeth and a second blade having a second set of cutting teeth, the motor operatively connected to the first blade to move it in a reciprocal motion;

the first blade having a sawblade portion with a third set of cutting teeth, different than the first set or second set of cutting teeth; and

the second blade has a portion free of cutting teeth and including a beveled edge extending in a longitudinal direction of the blade assembly, and wherein the beveled edge is adjacent the sawblade portion for assisting in helping cut debris pass over the blade assembly.

8. The hedgetrimmer of claim 7, wherein a portion of the first set of cutting teeth is on the first blade opposite to the sawblade portion.

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

10. The hedgetrimmer 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.
