  • Patent number: 5005597
    Abstract: Leaves and other debris arranged in piles along a roadway are lifted by a flail-type rotary cutting device towed centrally behind a tractor. The device includes a containment hood having a forwardly opening throat which is adjustable to conform generally to the size of the piles for receiving the piles and restricting the material from being thrown forwardly from under the hood particularly at the end of a pile. The lifted material is delivered into a receptacle towed behind the cutting device. The rotary cutting device can handle leaves and other debris in states ranging from dry and fluffy to frozen and snow-covered. The tractor and/or additional brushes may be used for preliminary piles sizing and positioning. Brushes may also be added to the machine for additional cleaning action and to help part wide piles.
