on my D4 6U with the 4S blade there is a hydraulic distribution block on the right front fender. this block has a lever and a set of blanked off ports so i figure it's purpose is as a selector valve to disable the blade and redirect the flow to another place like a rear attachment. not as handy as a double valve set up but should be workable as a farm cat. what i am thinking is try to find a set of compatible flanges to bolt to the diverter valve and run a set of hoses down the fender to the rear of the machine and weld a couple of chain hooks on both side of the cylinder brackets under the blade lift cylinders as positive stops to hold the blade while using the rear remotes. so a couple of questions are in order. where can i source the flanges and do you think this is doable?

Thanks John

I'm sure it's do-able...Check with General Gear and Machine for your parts..

You can make your own flanges. Flanges are flat faced, the o-ring seal provision is machined into the cross-over valve.

I have a similar set up on my 5T and the plate is 5/16 or 3/8 plate with 3/4 pipe nipples welded in. Should be pretty straightforward to build some

A well stocked hydraulic shop should have them or could get them. That is were I got mine.

I too have the valve and handle but I have two control levers what's up with that? I do intend on pulling a disc around the pasture if I ever get this thing running.

Vance I think you have a 2 valve 44 unit. The left lever is for the blade and the right lever is for the rear remote.

There are still only two pipes from the pump, so the diverter valve will have to be used to switch from blade to rear. I don't know where the other spool goes, could be on the left side

Vance,
look on the top of your hydraulic control at the front of the tractor. There are four pipe outlets, two of which are used by the pipes on the right side of the tractor as seen in the photo. The other two outlets may have blanking covers on them with two bolts each. If you were to remove those two blanking covers and fit up some pipes to the rear of the tractor, you could use your second valve to control trailed equipment independently of the blade valve, assuming that the control has the second valve components installed (they should be since you have the external levers etc.).

Stephen, on the 44 unit two lines came down the left side and two came down the right side. The diverter valve was used when all four lines were needed in the rear.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
