Question 8

How should the hoe be used

Answer 8

the cutting edge should be angulated at 90 degrees at the tooth surface
Ensure correct angulation is established before activating your pull stroke
This contact provides leverage and control for breaking off heavy deposits
The hoe should be used in overlapping strokes
