I have a TC25D and would like to install a rear hydraulic hook-up for a backhoe. Is this fairly easy task or should I let the dealership handle it.

Chris, you didn't tell us if you are going with the NH unit, or another manufacturer. Also, if the hoe is a sub-mount unit or a 3pt hitch type. Most dealers will make the installation for you if you buy the hoe from them. In any event you'll need to either tap into your power beyond hydraulic circuit, or if you choose, mount a pto driven pump kit. Neither of these are very difficult, however, I caution you about loosening and tightening any bolts related to your cast differential housing. Should you need to remove any to make your installation, if you don't have a torque wrench, rent a good one and find the specific torque value for each fastener you'll be working with. I also use Locktite liquid pipe thread sealant instead of teflon tape because I've had one bad experience with tape debris in the system. The only down side is it takes quite a while for the sealant to cure. Go slow and read all instructions ahead of time and you should be OK. ....

Ted, thanks for the input. I plan on getting the submount NH hoe. I found a used one for sale and was hoping the extra hydraulic connections were too involved to install. ....

Gary, I wonder if you can tell me what a single valve rear hydraulic valve kit should cost from NH. I was originally quoted $250 for one, but when I went to order, it was now $450. I was told that there was an error in the book used for the 1st quote. 2nd, is this something very difficult to install? My primary use is intended to be for a hydraulic top link... Thank you for all your help. ....

If the tractor is easy to get to a dealer, doing it yourself probably wouldn't save much. Most of the cost should be in parts and hoses, and installation shouldn't take much labour. I have a valved rear outlet, but I've been thinking about more valves or an unvalved outlet. It'll be a do-it-yourself project because I have to ship the tractor to my dealer. I believe the idea is pretty simple. It's just running the PB hose from the sump to a mounting bracket on a rear fender and terminating it in a female quick disconnect (the PB hose from the SCV to the sump probably is long enough to run to a fender, but its length should be checked). Then, run a hose from the PB port to the fender bracket and also terminate in a female disconnect. Then have a short hose made with male disconnects at both ends. The short hose plugs into the female disconnects for ordinary use. The hose is removed and replaced with the backhoe hoses when the hoe is mounted. The same idea works for installing valved outlets except for the additional complication of providing a low-pressure (tank) return if a 3-hose valve is used. There is a however. There would be quick disconnects in the PB line. If the disconnects ever pull out or fail, there would be a big uncontrolled oil leak. I imagine a good installation would have to protect the short line to prevent it from getting snagged during operation. I don't really know how advisable quick disconnects are in PB lines. ....
