Hi there and thanks for letting us in on your projects, Iエm new to this scene and also english is not my strongest language so pardon my spelling. You were saying that the teeth on your backhoe are making it difficult to get a good finish. I donエt know how it is in your homeland but up in the cold north we put a piece kind of like the mouthpiece boxers have....it goes over the teeth and has a flat cutting edge to get a smooth finish. It slips over at least two teeth and is fastened to the shovel with bolts or a chain.....do you know what Iエm getting at?
