I really like that these Rippers have a bolt on tooth that is easy to change in the field. However, finding replacement tooth with a hole drilled in it is difficult. I would like to see Vevor sell the replacement teeth for the shanks that they sell.
The shanks on these Rippers are made thinner than the original ones and they are not hardened steel, so in hard ground they bend. I have a couple of them that have bent beyond being useable.
