LOG SPLITTER FOR MY JOHN DEERE 790

[bottletree]

I have a John Deere 790 with a front end loader and I bought a log splitter attachment for it. I am having problems with the hydraulics. There are four ports for the front end loader. I detached two hoses from the loader and used these for the splitter. The splitter does not seem to work all the time. If I move the loader handle and tie it off, sometimes the splitter will work, and other times it won't. Never have any problems with the hydraulics when my bucket is hooked up. Does anyone else have run into problems like this? Maybe my 790 will not work a splitter.

A pair of the ports go to the loader cylinders and the other pair go to the bucket curl cylinders.
Which pair are you trying?
May depend on which pair you are using, and which direction you are tying off..

Tried both pairs and different directions. There has to be a loop somehow in the tractor system and I can't figure it out. I called the log splitter manufacturer and all I got from them is an open center valve or a closed center valve is "deadheading" on the tractor

I used my 770 ages ago the same way. Bunjied down the loader boom port (I believe) . No problem. Just very slow (on my splitter) for my liking. Make sure it's not going into FLOAT!

If it was deadheading the tractor, it would stall. Or the relief valves would be screaming!

I have tried bunjeing the lever for the bucket. I can get those relief valves screaming. That is one of the things worrying me. If they scream I have a feeling it is not doing my tractor any good. Assume you mean by going into float is where my lever is in a neutral position. Now just wondering if splitter is too much for my tractor. Hate to go back to using a maul.

Does the splitter have it's own control? If so, you'll be better off adding a Power Beyond kit

The neutral position is NOT the float position. Float is a detent position beyond the "normal" range of the lever, not all valves have a detent. If your relief valve is screaming, there is no fluid flow (or very little) in your hydraulic circuit, it is all being dumped back into the tank before any of your valves.

How about a picture of how you have it hooked up?

 

[bottletree]

Food for thought. Tried looking on line for one to price . Scarce as hen"s teeth.

These are the pictures

I don't think a loader valve is setup for unimpeded continuous flow like you need with a splitter. At least not in a consistent reliable way. Someone else may be more familiar with the hydraulic circuit on the 790 but I think you need to tap into the circuit downstream of the loader valve. The splitter needs positive pressure inflow and unimpeded outflow back to the reservoir.
