Abstract: A wood chipper comprising a pair of horizontally spaced-apart upstanding end walls having a plurality of rotatable shafts extending therebetween. The shafts are arranged so that they define a semi-circular configuration when viewed from the ends thereof and which define an open upper ended wood receiving area between the first and second end walls. A plurality of horizontally spaced-apart chipping discs are mounted on the shafts between the side walls and have chipping teeth extending radially therefrom. The chipping discs are offset or staggered on the shafts so that the chipping discs of one shaft may extend inwardly between the chipping discs on adjacent shafts. When wood is placed in the wood receiving area, the weight of the wood causes the wood to be brought into engagement with the rotating cutting discs to chip the same.

Abstract: A herbicide disperser for selectively controlling unwanted weeds without killing the desired grasses. The apparatus includes a central frame generally transversely disposed with a pair of rear wheels and a front wheel for mobilization. The frame has a herbicide storage tank mounted to it, tubular handles for manual pushing and a forward and rearward series of spring tines which aid in guiding the unwanted weeds upwards to a wick assembly which saturates the unwanted weeds with herbicides. The tines are able to distinguish between the desired grasses and the unwanted weeds in that the unwanted weeds are longer and are picked up by the rearward tines and guided to the wick assembly and the desired grasses are passed over.
