Using FEL controls for rear remote

[Percy23842]

I was wondering if it's possible (or even a good idea if possible) to use the FEL controls on a TC30 with a front end loader to operate 3 pt hitch equipment that uses hydraulics. I was thinking of just removing the loader and running hoses to the fel inputs since the 3 pt hitch equipment will be used sparingly and probably wouldn't justify the expense of adding a rear remote, though not totally out of the question. Thanks for all input.

It's not a problem at all to do that. Some even leave the loader on (for front ballast) and use the dump/curl circuit at the rear while leaving the lift/lower circuit hooked up to the loader in case you need to move it up or down. Just get some longer hoses and your all set

Thanks kenny, much apprecaited.

Just remember that the joystick pushed all the way forward goes into float and pushed all the way right goes into regen in the dump circuit. Otherwise, the valve is nothing more than a dual remote controlled by a single joystick. You will also find that most NH rear remotes are 1/2" QDs, while I believe your loader is 3/8" QDs. Make sure you have the right fittings.

I was able to do this and was actually given a drawing by my local NH dealer. If you add a QC to the loader return circut on the joystick control to feed the input on you 3 pt. attachment and then add a QC directly to the 3 pt lift block for the return it works great. You will have to remove the hard pipe froom the loader return circut and replace it with a hose and QC but all the parts cost less than $50. It is IMPERATIVE !!!!!! that you have either the loader return circut hooked up or the attachment hooked up or you WILL blow up your hydro pump. It will deadhead at the fitting and wreck you system. If you need pics let me know. good luck.

I know you said this was done sucessfully by you with your NH Dealer, but this spells trouble "If" operator error kicks in....The way KennyD mentions has the connections after the FEL valve eliminating the possibility of major damage to your equipment and/or you.....If you're gonna do skinnr's way an extra PRV needs to be plumbed inline just after pump with a return line......If it can happen it probably will....:ashamed:

I agree anything is possible. I chose to do it this way sinice I do not do much backhhoe work. If you are serious about using your backhoe and are going to be leaving it on for long periods of time I think I would spend the extra coin and just add a remote. I saw in another post that woods makes an adaptor plate to add to the 3 pt lift case to power up a backhoe and I know I have one somewhere in a box. I will add pictures of both connections on Tuesday when get back in the shop.

IF the rear attachment does not have a control valve you can use the FEL control valve to operate the cylinders or motors.

If your rear attachment has a control valve I would caution you on how to supply oil to that valve. If the rear valve does not have a power beyond feature you can still use your FEL control valve to supply oil to the rear valve. Plug your rear valve couplers into the couplers for your loader and tie the FEL handle back to supply a continuous flow of oil to the rear vavle. NOTE; Your three point hitch will not work with this setup as long as the FEL handle is tied back.

skinnr's suggestion wil work but it can have some unintended consequences. At your FEL control valve you have three lines that come from the manifold block, pressure, return, and power beyond. I believe skinnr meant power beyond and not return since there is no pressure in the return line since it goes directly to sump. What happens by tapping the power beyond as suggested is all the oil from rear control, both free flow oil not used by the rear valve and oil exhausted by the rear cylinders when the rear control lever is moved, goes back through the power beyond line and then to the three point hitch control. Now suppose you want to lower a rear cylinder and also you want to raise the three point hitch. As you know with your loader it does not take any oil pressure to lower the loader, but since the oil from the rear valve is going directly to the three point hitch by way of the power beyond circuit, and the three point hitch needs pressure to raise you now have just pressureized the complete circuit and instead of the rear cylinder exhausting oil to lower it will be pushing oil through that circuit and the cylinder will extend instead of retract. Will it happen to you in your use? I don't know but I have seen it happen. Also most valve manufacturers do not recomment pressurizing the control valve like this because of a possilbe valve body fracture. That is why your loader valve has three ports to the manifold block.

I would just add a separate joystick and plumb it in series with the power beyond, then you have it and can use it when the loader is on as well. In the end you will be glad you did. We spend so much time trying to cut corners and in the end it is way simpler just to do it right the first time, learned that lesson a few times!:mur:
