<p>Apparatus for cutting tree parts adapted to be operatively mounted on vehicles including a base structure configured to define a concave cutting recess for receiving therein the tree part to be cut with at least one pivotable holding arm adapted to grip a tree part engaged within the cutting recess and with a cutter plate having a generally planar configuration and defining a cutting edge adapted to be moved through the cutting recess to cut the tree part held therein. The cutter plate is pivotally mounted on the base structure for movement through a cutting operation by pivotal motion thereof and a slotted guide opening is defined in the base structure between the cutter plate pivot and the cutting recess through which the cutter plate moves during a cutting operation. The cutter plate thereby is capable of projecting freely through the slotted guide opening into the cutting recess over the sector of the cutter plate adjacent the cutting edge thereof by passage of the cutting edge through the cutting recess.</p> |
