The angle gear has two purposes:
The first is to gear down the engine’s high speed to better suit the lower speed a saw blade or trimmer
requires to work efficiently.
Secondly, the angle gear contributes towards the operator’s working stance so that it is comfortable and at
the same time efficient. In other words, the power from the engine via the drive axle should be angled so
that the cutting tool works parallel with the ground.
