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
you can get a small centrifigal pump that only takes about 3-5 gpm, power beyond will only work if you have a load somewhere that requires full pressure. i.e. if no load you only have about 300-500 # pressure, but with a load such as the vac fan you should get up to system pressure (usually about 2600 psi) then the pump will be constant.
we run one hyd pump for a 5gpa rate in furrow. if that helps you any would not trust the 3 way valve to not open to bleed off prssure then you have blown lines, etc
edit: vac fan should take about 12 GPM, pump 5GPM so leaves you with 12 for lift. we tried much more stuff with 49 GPM went to 59GPM now with even more needs we are running 85 gpm. oh the latest tech is not all roses
