pto hydraulic pump for john deere 7200 planter factory

PTO-driven hydraulic vacuum pumpThis attachment allows using the vacuum seed meter system pump with tractors having an open-center hydraulic system and/or a 540-rpm or 1000-rpm PTO.

Flat seed disks such as edible bean and sweet corn require high levels of vacuum. These disks require a dual vacuum motor configuration on planters over 8 rows. The 1000-rpm PTO pump is not adequate for this application.

I bought a 7200 6RN that I want to put a PTO pump on. Pulling the planter with a 30 series John Deere and don"t want to spend the money on Power Beyond or worry about burning out the hydraulics. I bought a pump off an 800 IH planter. Has anyone done this? Does it work? Anything special I need to do. Can these pumps be rebuilt if it doesn"t work? Thanks a lot guys.

We usually pull our vacuum metered 7200 6/30" with Dad"s 4320, last spring the 4320 went down and it was going to be a couple weeks to get it back up & running. Out came the 1964 3010D. I had my doubts, but the hyds on that tractor were plenty to run the vacuum / fertilizer auger & lift. It sure was a handful getting over the sand hills power wise, the old NA 4 cylinder was smoking & throwing sparks giving everything it had, the front wheels were even floating from time to time. Was kinda fun, it"s not every day that planting feels like tractor pulling.

That said, with a little prep and if your on relatively flat ground, a MX110 will probably handle that planter. The hyd will run everything just fine, it"ll just struggle some when pulling a hill or soft spot. Might have to drop a gear lower than you like & probably will need some extra weight on the front.

For a PTO pump, when you start adding up the parts & headaches trying to design your own, I think you"ll find that $1800 is actually a pretty good deal. Especially if you consider the chance of putting something together & it doesn"t work out. We"ve all been there, something looks great on paper, you spend a couple days getting it all set up, then find out you"ve got to start nearly from scratch again. Get into planting season & it isn"t working, you"d gladly spend $1800 to get out in the field.

The drill is used for planting what’s called a “solid stand” – usually a grain. For corn and dry beans, we needed yet another new piece of equipment, a row crop planter.

As usual, this one also required a lot of attention before it got its first run around the field. A Deere 7200 6-row vacuum planter (purchased used, of course), it requires two hydraulic hook-ups. Unfortunately, the tractor we’re borrowing from my uncle Johnny for this purpose only has one place to hook up hydraulic hoses. So, my dad and our intrepid friend Butch figured out a way to make it work by adding all these black boxes and hoses:

(For the mechanically inclined: that’s a PTO-driven hydraulic pump, with a hydraulic fluid reservoir and a hydraulic oil cooler with an auxiliary fan.)

John watching the computer monitor while trying out the planter for the first time on sweet corn. It’s hard to watch the screen and drive a straight row at the same time! Fortunately there’s not much traffic on the field, so he just has to worry about how it will look after the crop comes up.

It worked on the sweet corn, and we didn’t have to make too many upgrades and modifications before planting our four varieties of edible dry beans, and then soybeans.

Shortly after this picture was taken during the bean-planting, however, the tractor (a Deere 4010) we were borrowing started having trouble. The battery kept dying, and then when we jumped it with the pickup truck, it sometimes wouldn’t throttle up enough to go. Finally we figured out that we were asking more of this beautifully-maintained 1964 tractor than it was designed to handle – both the fan and the computer were drawing down the battery, and the alternator couldn’t keep up. We unplugged those electronics and finished up as quickly as we could before the rain.

Prince PTO pumps are specifically designed for PTO drive operation on all sizes of farm tractors. No additional gearbox is required. Pumps are mounted by sliding the internally splined pump onto the PTO splined shaft and restraining rotation with a torque arm. See page P6 for the PTO pump torque arm kit.
