An apparatus and a system directed to a towed device powered by a tow vehicle. The apparatus and system include a woodchipper configured to be mounted on a towed vehicle, with the towed vehicle configured to be towed behind the tow vehicle. Additionally, a motor may be coupled to the woodchipper to provide power to the woodchipper. A power converter obtains power from the tow vehicle from a power takeoff coupled to the tow vehicle. Further, one or more power transfer lines connect the power converter with the motor to communicate motor-operating power from the power converter to the motor.

A flywheel and paddle assembly for a chipping or shredding apparatus, including a wood chipper, a brush chipper, and a leaf shredder. The assembly has a flywheel attached coaxially to a drive shaft. The flywheel has at least one aperture extending from the front side to the back side, and carries at least one knife adjacent to the at least one aperture. The knife presents a knife edge on the front side of the flywheel. A paddle is rotatably mounted coaxially to the drive shaft adjacent to the back side of the flywheel. The paddle is configured to rotate on the drive shaft independently of the flywheel. A chipping or shredding apparatus incorporating the aforesaid flywheel and paddle assembly is also disclosed.

The present invention relates to a counter-blade, in particular, for a wood chipper, for producing wood chips, comprising at least one cutting edge made of a hard material, and a support surface leading to the cutting edge. According to the present invention, the cutting edge is made up of a plurality of hard material elements that are arranged next to one another along the cutting edge on a main member. This results in a counter-blade having a long service life.

A chipper includes a hopper and a chipper unit. The hopper is configured to receive vegetative debris via an inlet end. The chipper unit has an outer casing and an inlet passing therethrough. The inlet of the chipper unit is connected to the outlet end of the hopper to in use receive the vegetative debris within the outer casing. The chipper unit includes a cutter located which is configured to chip vegetative debris. The hopper and the outer casing are configured so that the hopper and outer casing can be moved between a position where the hopper is substantially vertical and a position where the hopper is substantially horizontal.

A machine or device for reducing material including a cutting drum and/or removable, multipiece cutting blade assembly. A machine for reducing material that includes a skinless cutting drum. In one aspect there is disclosed a woodchipper for reducing material that includes a skinless cutting drum and a discharge assembly.
