Gear Head; Dismantling - Husqvarna 545RXT AT Workshop Manual

Gear head

The gear head has 2 purposes:
The first is to gear down the high engine speed to better suit the lower speed a saw blade or trimmer requires to work
efficiently.
Second, the gear head contributes to the saw operator's working stance so that it is comfortable and at the same time
efficient. The power from the engine, via the drive axle, shall in other words be angled so that the cutting equipment
works parallel to the ground.
WARNING: Always use gloves when handling hot objects.
