Dual implements on a JD 620

DavidT1 · Jun 4, 2014

Hello All,
I am hoping to get some info from the people that would know. I was wondering if it is possible to have two drawn implements hooked up at the sametime to a JD 620 and be able to run the hydralics on both?

I would like to be able to hook my disk infront of my drills and be able to lift them both at the sametime.

Can this be done? If so what would I need to do?

Thanks!!!!!

for a down and dirty method, without adding a second spool valve, jut put tees on the disk cylinder and hook the hydraulic hoses from the drill to the disk. they will raise at the same time, and drop at the same time ( or shortly thereabouts. )

You can add an open center two spool valve by feeding the output of none port to the input of the valve, then plumb the outlet port of the valve back to the other port of the power-trol valve. Then block or tie the power troll lever in position to feed the added valve. I use this method on my loader on my JD A. This will allow independent control of both drawn implements. Glennster's idea is the simplest way to do it if you want them both up or down at the same time. The unit that is easiest to lift will raise first, as soon as it is all the way up, the other will raise. You may not be able to precisely control the depth of the drawn units, but if that's not important it sure is easy.

They made dual hydraulic box's for just that purpose.

Thanks to all who responded. I am going to try and find a dual box and if that does work try the other ideas. Again thanks!!

The 620/630 could be factory optioned with dual SCV . A
salvage yard somewhere will have a bolt on solution that
doesn"t look and work like a "farmer fix".
