Sharpen Mower Blades with Angle Grinder

What happens here

Wearing safety glasses and gloves, the host uses an angle grinder to sharpen the mower blades while they are still attached to the bush hog. He explains that for a bush hog, the blades do not need to be razor-sharp like a lawnmower blade; the goal is to remove any flat spots, gouges, or nicks caused by hitting rocks or other debris. This allows the blades to efficiently 'power through' and cut vegetation rather than tearing it. He also warns against over-grinding one blade more than the other, as this can create an imbalance, leading to vibrations and loosening of components.

Goal: Sharpen the bush hog blades using an angle grinder to remove gouges and flat spots, ensuring effective cutting without needing a razor-sharp edge.
