I live in Northern California and I do commercial disking. All my disking are smaller parcels and up to about 5 acres. I have an old Killifer 8' 4 gang and a Killifer 8'3" offset. These are both old disks and I am tired of having to repair them, so I have decided to sell them and buy a new, or almost new 8'3" offset wheel disk. I am not sure what is available in a heavy duty offset disk. I have been looking at the Domries offset that looks pretty heavy duty. Any others I should be looking at?
