The vacuum planter will work fine on any Deere tractor starting with the 10 series up to the current models. You DO NOT need a pto unit. If a Deere dealer sold one to a Deere tractor owner, he fleeced him. You see, Deere built their planter to work with a Deere tractor, or any closed center hydraulic system. It would be silly for a company to market a planter that doesn't work with their own tractorIJIJIJIJIJ The vacuum motor uses very little oil, no need to return to the filter. We have hooked lots of these right to the scv with both hoses with no problems. The back pressure isn't really much of an issue. If you feel you need to have a dump, you can do that by hooking into the side of the scv.
