860 hydraulic problem

tractorguy2 · Dec 9, 2016

This 860 has a problem with the hydraulics. The 3pt works fine. The problem is with the remote valve. The valve is a Cross that
someone rigged up. Been this way for 30 years.The owner said it never worked very good. Now it won't raise anything. If you pull
on the remote lever the 3pt will drop about 2 inches and then come right back up when you let go of the remote valve lever.

I thought the 3pt had to be raised up in order to get pressure at the port he has the cross valve hooked to?

I took the side cover off and looked inside. The cylinder was leaking a steady small stream of oil. I know that needs a new o
ring.

I have always been told for that type of set up to work one has to chain the 3 point arms down other wise you will have no pressure to work with. Years ago I tried the do something like that on my 841S and found it would not work well to run the loader due to many odd problems like the 3 point having to be locked down etc.

That's what I was thinking the 3pt had to be chained down.

I'm using a similar setup on my 871 to run a logsplitter. My plate has a "diverter" valve on it. I pull that out, make sure my lift lever is up, and it works fine. I've never had to chain my lift arms down as long as I pull the diverter out. Is there something here that I'm missing? I can take a pic of my setup if it would help.

Here's a couple of pics of mine. I got the diverter plate at TSC years ago, pretty cheap, as I recall.

our diverter valve makes it where you do not need to chain arms down. He does not have a diverter valve. In his arrangement, he has a remote valve tapped directly into the 3 point lift cylinder, therefore the fluid will take the path of least resistance, i.e., raise lift arms if that requires less pressure than whatever he has connected to remote, or lift that remote load if it takes less pressure than lifting the 3 point load. To make it lift the remote load, chain arms down, making the remote load the easier of the two to lift. Simple.

Order this from Yesterdays Tractors and install it under the port cover.

This is the way my 3000 is set up with a loader plus rear hydraulics and other than the aux stuff being a little slow it works great.

Hay Guys get the cast iron and galvanized pipe fitting off the hydraulics I worked 30 years as a mechanic in the coal mines and hydraulics are dangerous CAST and GALVANIZED fittings blow up easy. Use approved hyd. fittings

You need to chain the lift arms clear down to the bottom for your remote valve to work efficiently. If chained in another position you have to wait to refill the tractor hydraulic cylinder every time you change direction of the oil through the remote valve.
