JD 2840 HYDRAULIC LINES for BUSH HOG Shredder connections

bennettranchncattle1911 · Jun 8, 2015

I have an old JD 2840 with a FEL. I am trying to hook up a Bush Hog Shredder to it but am not sure where to put the hydraulic line from the shredder to the which line slot in the 2840. Currently there are no open slots in it so one of the 4 hydraulic lines would have to be removed. There are two lines on the rear right and two lines on the rear left. Any ideas or suggestions?

I would disconnect both hoses that control bucket curling. Then plug cutter hose in the LH breakway outlet. Then when you move SCV toward the rear cutter should,move lever forward cutter should lower.

Way back when somebody blotched the loader install the troubles started. They used the SCV's, which returns the loader oil direct to the transmission case. Not good as the transmission pump is undersized.
Unless the raely seen optional return line to a ported filter cover was used from the SCV drain port. Which Deere recommended for high flow loads.

The only real fix is to install a joystick control on the loader. Then connect the loader having nothing to do with the SCV's. Use a direct feed line to the joystick, T'd into the line supplying the SCV valves. Return the loader oil direct to a ported filter cover.
You will be shocked at how much faster and quieter the loader operates when the front pump is no longer starved for oil.

buickanddeere has the right idea. You would be much happier with a dedicated loader valve.

Question....SCV is service control valve right ??....I'll be working On it in the morning and would greatly appreciate a phone call with some guidance . the hydraulic line is hard to disconnect and am wondering how much force I have to put on it to disconnect ?
