Description: The disc harrow I have leaves large gullies on each side. So I built this tool to fill in and level out the gullies. It can be mounted on a tool bar or mounted right on the back of my disc harrow.Add new comment Documentation Image Gallery: Documentation Wiki: Spike harrow shown mounted to disc harrow.Add new comment I like this tool up0 users have voted.
