BH77 and third function valve

[Ryansweatt2004]

Hey everyone, I'm waiting on delivery of a new L3901hst with BH77 backhoe. My current L3901DT had the landpride 3rd function kit that I installed. I'm getting ready to pull that whole 3rd valve kit off the old tractor to install on the new tractor with the BH77 once it arrives. Has anyone ever installed a third function valve to their hydraulic system with a backhoe already hooked up and how did it go? My landpride directions don't say anything about hookup if a backhoe is involved and google hasn't produced any directions or schematics for the hydraulic system. Any help or pics would be greatly appreciated.

I'm not sure if this will be of any help. I added a W&R Long 3rd function valve to my old L3430 HST with BH90 hoe. Per the instructions, the valve plumbing was installed between the tractor hydraulic block and the pressure side line that went back to the hoe. 2 longer hoses were required that weren't part of the valve kit. The BH pressure line was removed from the hyd. block and replaced with one of the longer hoses leading up to the valve. The other long hose went from the valve back down to the disconnected BH line. The 3rd function valve was essentially installed in series with the pressure line to the BH.

FWIW, the W&R Long valve was installed the same way on my MX5800 HST with BH92 hoe.

This was for a W&R Long valve kit on an older tractor, not a Landpride on a L3901. I suspect the installation will be basically the same but I can't be sure.

Good Luck!

Thanks, I think I've got it figured out now. Just have to wait until sometime next week when the new tractor gets delivered before I can try installing the 3rd function.

Sir, I have the landpride 3rd function and am adding the BH77 (used). Would you mind describing how you connect the lines to the backhoe need to be ran? Thanks so much!
