Thinking about a hydraulic thumb for a L47

[waltwhit]

The L47 has two pumps supplying the backhoe, I think. Make sure you have a WSM and understand how that works.

Will check that out before doing anything. Thanks for info

I kid you not, but as i said looks like that number is out the window. I have been wrong many times before.

Well, then, could you use this as a third function for a grapple, etc.?

Could one of you guys post the L47 hydraulic diagram from the WSM?

That helps. Could you also post the one for you tractor?

While I love my BH, and thumb ... I don't use the thumb a lot, but since I added hydraulics to it, I do find I use it more than I use too!

Since I'm cheap and I had a 4 spool valve for my rear remotes, when I have the BH on, I ran one of the rear remotes to the thumb ... Cost basically for just the hoses and cylinder, although I did add a CRV to it to protect the cylinder ...

Here's a short video ... Hydraulic thumb

Tractor came with factory third function installed. And thanks everyone for your input.
