SW Ohio | I have a John Deere 1760 planter that has the factory fertilizer tanks and is currently setup for in furrow with a manifold and electric pump.
I am going to switch from in furrow to dribble a UAN/ATS blend behind the closing wheels.
I originally was planning on a ground drive piston pump for simplicity but then I've been thinking about the need for section control.
Individual row shutoff saves me around 11% on my seed here with our small, odd shaped fields so I'm thinking that I could get a similar fertilizer savings if I could break my 12 row planter down into either 4 or 6 sections.
I would run it through my Ag Leader Incommand that controls the clutches.
Is it feasible to setup section control on a positive displacement ground drive pump? Is there a good way to do this other than 3 way valves? It seems a little complicated in my head.
Should I just forget the ground drive and go with a hydraulic centrifugal pump? My hesitation comes from being worried about having enough hydraulic output. The tractor is a McCormick MTX 125 with 29gpm hydraulics, could I run a hydraulic pump off power beyond and still have enough for the vacuum fan running eSets and not lift crazy slow?
Just looking for ideas and input.
Thanks | |
