| I don't know anything about stack fold bars. They're not too common around here but it sounds like a reasonable idea as long as like you say, you have it empty before you fold up. I wonder how a rig like that would work going around curves? It seems like the planter might follow a different track than the stack fold bar and you wouldn't have the band in the place you wanted it relative to the seed. This would be an uncommon scenario though.
I know our old 7200 has liquid tanks sitting right on the frame of the planter. Maybe you could put dry tanks right on the frame of the planter and then use the single disk openers again. You wouldn't be able to use it as a side dresser after planting though.
You're right, the hydraulic capacity is quite the issue. We're considering buying a 1770 (not the NT) that is already set up for dry from one of the farmers that's been using this setup. It's chain drive so all we would need for hydraulics would be the vac fans, lift and the air cart. Not having the CCS fan or the hydraulic drives should significantly lighten the hydraulic requirements. We're planning on pulling this with an old JD 4840. We would run the fans on the planter and the lift with the tractor hydraulics and then get a PTO pump from http://www.rowemfg.com/ to drive the CCS fan. I called them today and I'm pretty impressed with what they claim to be able to do with a simple PTO pump. They mount a reservoir on the planter, and they have what they call the Pump Doctor which mates the pump directly to the tractor so it's not wobbling around all the time. He only uses close center pressure compensating pumps and his largest pump puts out 21 GPM if you're running at PTO speed. He has a step up drive that increases the speed to what the pumps max RPM is as well and that is supposed to bump the GPM to 47. It sounds like it would be possible to run most planters with a setup like this even on an older tractor.
I guess I've rambled enough. I've been trying to figure out a hydraulic solution for awhile now and I'm kinda excited about finding something like this. It is starting to look like we're not going to have to do a $100,000 tractor upgrade to take advantage of the cost benefits of dry fertilizer. | |
