1586 hydraulics question

Dave H (MI) · May 27, 2014

Talking with Molineguy over on the implement board and the subject came up about plumbing my corn planter directly to the tractor hydraulics instead of having the pto pump. He said his 1586 ran a tad slow and did not have the pump output to raise the planter and run the blower. Specifically he said he had to stop at the end of rows to wait on the planter to raise fully. I mentioned it to the service manager at the dealership. He says he didn't think it was an issue. Wondering if anyone else is experiencing what Moline has going on? Dealers don't always give you the straight story.

A 1586 has load sensing pressure compensating system, If it is to slow, It has a week pump or is out of adjustment, It is a complicated system, unless you know exactly what you are doing, don"t mess with it...

Not all 1586's had the pfc hydraulic system just the later ones. Earlier ones had the gear pump that IH had used for years.

Either way guys, I guess I wasn't clear enough. The chat with the service manager is because I am having mobile service come out and deal with the issue. I wasn't planning on tackling 1586 hydraulics in the field. Don't have the experience or the time. I just wanted to know if anyone had experience with the pump not being up to two tasks at once. For example, I have noticed that my 25' disk does not want to raise and fold at the same time. I do one then the other. Thinking it will be this way with the planter also, like the fella had mentioned.

If ya got the pfc hydraulics, turn the one for the motor down with the control, not a cheap regulator plumbed into the line like JD did with 2 of the last 3 planters the boss bought, trying cause slow lift and to burn up pumps and sell him a new tractor.

If you have the PFC system you can set the motor valve to have a constant flow and the other valves can use the remainder of the pump output even if they require higher pressure.

On the earlier system the control valve that has the lightest load will use all the flow until it reaches the end of travel and causes the pressure to rise so that the flow will go to the other valve. You can control this some by using restricters in the line but then the system will go on high pressure unless all the flow is being used between the valves.

Thanks Owen! I believe I have the older system then. When I want to raise the disk AND the wings on the disk if I hit the controls at the same time only the lift works and once it is up the wings raise. I have to think there is a reason they put those drawbar pumps on the old planters and this is it. Obviously the direct connection would be better/easier but the hydraulic system as designed would make it inefficient. Appreciate the insight.

I think I am staying with the drawbar pump. As long as it plants it is not that big a deal to put it on.

I don't know what the 1586 is rated at for flow, but the JD 4840 with the big replacement pump lifts noticeably slower when running a vacuum planter.
We were looking into a PTO-driven, stand-alone hydraulic system for the 16-row, til the 4840 decided it needed more transmission work that the tractor is worth. Even with the Steiger on it,would have needed one for a 24-row, but ended up trading back down to a 12 row to match the combine and not have to level out all the terraces.
