ABSTRACT:
A powered pruning saw is disclosed in which a drive motor is connected to an elongated drive shaft rotatably held within an shaft or pole. A gear head is mounted at the other end of the pole to the remote end of the drive shaft. The gear head includes a gear housing formed of two housing halves, with a pinion rotatably mounted by a pinion bearing within the gear housing for coaxial rotation with the drive shaft. The pinion shaft mounts the pinion at one end and a drive shaft receiver at a remaining end for releasably receiving an end of the drive shaft. A cutter arbor shaft is also rotatably mounted in the gear head, and mounts a gear in meshing engagement with the pinion. A cutter arbor shaft bearing mounts the cutter arbor shaft and gear for rotation about a cutter arbor shaft axis that is angularly offset from the drive shaft axis. A cutter is releasably attached to the cutter arbor shaft. The gear housing halves are joined along a plane normal to the cutter arbor shaft axis and include journal boxes formed therein for receiving and clamping the pinion bearing. Clamp members join and fasten the housing halves together with clamping forces substantially parallel to the arbor shaft axis. Also disclosed are apparatus for installing sleeves over selected lengths of the shaft or pole by selectively expanding the sleeves and providing low friction surfaces over which the sleeves may be slid. Also disclosed is an apparatus for dispensing a measured quantity of fluid lubricant to the cutter by tipping the saw.
