ABSTRACT:
A hedging apparatus is disclosed which comprises a wheeled vehicle having a specially adapted chain saw thereon for cutting limbs and branches from trees, hedges, or shrubs, which are planted in rows. The chain saw is provided with a plurality of spaced-apart guide bars which extend forwardly of the cutter chain, thus assuring the severing of limber branches which would otherwise be pushed aside by the saw and remain uncut. Resilient springs in the form of elongated rods can be used in conjunction with the guide bars to prevent chattering of the branches being cut. To particular advantage, a positioner can be provided for setting the chain saw blade at a selected pitch angle and for maintaining the selected pitch angle during a hedging operation. To further advantage, a hopper can also be provided for collection and disposal of the severed limbs and branches during the hedging operation so that they do not have to be subsequently gathered up and hauled to another site for disposal.
