I thought all was good until shortly after the Cheetah blades were installed and I had started mowing. The rural mowing I do is relatively rough, especially where feral pigs have been digging. With each rough patch one of the Cheetah blades dug a circle in the turf.

Some of the divots were 2" deep at the edge. I slowed my mowing and it still happened. I raised the deck and it still happened. Several times the blade took such a solid bite that it stalled the engine.
I would have stopped after raising the deck.
