Keyshunter, have used moldboard all my life too, on farm in PA. never had problem with ground build up on moldboard, just trash build up. Have plowed in shell, sodand clay ground on farm. 1 bottom and 5 bottom semi-mount 18" . I have seen plows fall down because guys didn't support the plow when changing shares ,etc. And tractors flipped when guys plowing, don't know how they did it, they said tractor or something caused the flip and not them. SORRY for the way said that didn't mean to upset anybody. But if MM11 never did it before, just giving some warning so doesn't get hurt. there enuff accidents in farming with people that do have experience.
