Abstract: A vegetation cutter having a mulching blade system including a cutting blade and an independent vortex inducing blade. The cutting blade performs no vortex inducing function but rather only operates to cut vegetation. The vortex inducing blade is designed strictly to provide vortices at the outer ends thereof, and does not perform any cutting function. The vortices operate to even more effectively suspend vegetation trimmings within a volute cutting chamber of a deck of the vegetation cutter such that the trimmings can be cut several times by the cutting blade before being deposited back into the vegetation over which the cutter is traversing.

Abstract: A power tool having a low frequency reduction apparatus includes a first handle portion, a second handle portion, and a dual-density bladder disposed between the first and second handle portions. By disposing such bladder accordingly, the second handle portion is effectively isolated from the first handle portion, thus reducing the low frequency vibrations transmitted to the second handle portion. Preferably, a gap is formed between the first and second handle portions. In another embodiment of the invention, a dual-density bladder between a handle portion and a main housing portion of the power tool.
