. | What is the difference? I know my red tractors have open center hydraulic systems, and the Oliver 1855 I used to have and the 4430 have closed hydraulics. My son went out and bought a John Deere 1750 (i think) VRT planter this spring. From what I can tell the John Deere is the only one he can use on this planter due to the closed center hydraulic system. Is there any kind of get around to use on open center systems like a PTO pump? I am thinking of purchasing another tractor and it will probably not be a John Deere, but I would like it to be capable of being the planter tractor.
