    Installing a rear 3 spool SCV valve on a 2720

    I purchased a Bucher 3 spool stackable section valve from Brian at Fit Rite Hydraulics. The valve is open center with two sections having a DA (double acting) cylinder spool with float while the last one is a regular DA cylinder spool. The valve comes with a PB sleeve in it for those that plan on using it. You can remove the sleeve and put a #8ORB cap in it's place if you don't plan on using PB like me. The valve is very compact measuring just over 6" wide across the sections. It has mounting brackets already on it as well. I chose to get 1/4" QD's mounted directly to the work ports on the valve for the most compact package I could get. I plan on using the two valves section with float for a future Top and Tilt kit also from Fit Rite. The regular valve will be used mainly for my MMM independent lift cylinder. I'll no longer have to switch hoses to go from loader to mower and vise versa, nor will I have extra hoses hanging out on the right side of the tractor.


    Here's how the valve came to me right out of the box.

    One might expect a box full of parts when ordering all of this, but Brian asked me how I intended to install and use this valve when I purchased it from him. It was assembled with the QD's installed with the appropriate thread sealant on the fittings, handles on the opposite side of the valve from the work ports, and stacked in the correct order. I didn't have to do anything but mount it and put into service.



    Next I needed to start building a bracket to hold my new valve. It's pretty self explanatory. I used 3/8" x 4" flat bar and a tab left over from the mower install kit.

    Here's it is all mounted up. There's a pic showing the two top spools in the float position. It looks like there isn't much room, but there's about 1/2" between the handle and the ROPs. The green tape is keeping dust out of the PB sleeve (located on the very top of the valve in the pic). It will not be used in this application. I'll remove it and cap the port. The top blue cap is the tank port which will be returning oil to the rockshaft. The bottom blue cap is the inlet port.

    Now I need to paint the valve and the new mount. Then I get to do some plumbing.

    I ordered the plug needed for adding the PB loop to the 2720 and the replacement O-rings for the adapter plate.

    So far the valve looks like it's of very good quality and is very compact. All great features to have in the SCUT or CUT tractors.

    Jason, is there not pressure to the rockshaft?

    Unfortunately I don't have a tank return port on the transmission case, at least one that I'm aware of. So I can't use the PB, I have to use the return port on the valve with the PB sleeve removed to power the rockshaft. It's the same setup with a factory PB loop option to power a BH.

    The difference is with a back hoe in place, you do not use the 3pt hitch and the oil just continues through. Now you will be using the 3pt and putting back pressure on the out port of the new valve. Will it work? Most likely. Is it rated for this? No.

    Is there no other point on the tractor to be able to dump the oil from the out port so as to be able to use the power beyond?

    Unfortunately there isn't a port readily available for oil return that I know of. Maybe with some creative thinking one could be found and used.

    Doesn't the factory PB kit have a "direct to tank" fitting? I know the 3x20's and 4x20's do. I looked on JD parts, but the image wasn't too detailed. I thought it looked like it had 3 fittings though.
    Your float function may work a little "goofy" without a tank port.

    Yes, the 3 & 4 series among other LCUT tractors do. There is no reference in the PB installation instructions nor the tech manual for 1 & 2 series for a tank return.

    I'm going to look tomorrow and see if there's a fitting or place that can be used.

    I've got a drill and a selection of taps...

    Looks good! Can't wait to see it all painted and plumbed.

    Jason, I like the layout. You put some real thought into this. I didn't know you could lay these valves out this way. It has me thinking more on the whole layout for my 990. I will be contacting Brian about getting the valves but maybe I should wait until I get all the other pieces in. I ordered the new ROPS tonight. The rest will be ordered on Monday. I will have a lot of work to do and it will have to be done over several months.

    I can't wait to see everything hooked up and painted.

    It sure would be nice if you could find a return to tank port.
