Backhoe attachment hydraulics

[Fitter274]

Hi All,

I have a hoe attachment I think is a 92 or 95 on my 450 loader. I wanted to change the quick connects on the hydralic lines, and made the dumb mistake of mixing the lines up. I know which is supply and return on the tractor, but how do I figure out which goes where on the hoe? If I hook it up wrong will I know? Or worse cause damage? Thanks, Brian

Shouldn't hurt anything. It'll just run backwards.

We had steel washers the size of just over the thread on the couplers on one of the hoses for each end on the 550 we had a hoe on .Digitup.

Once you get it figured out, if you switch one quick coupling around so you have one male and one female on the crawler with its mate on the hoe, it will be obvious where the lines go in the future. Also when the hoe is off the crawler you can hook the lines together to keep the dirt and ??? out of the system.

O.K. I got it. As luck would have it, when I fired it up and tried the hoe, it didn't work. 50- 50 chance, right? I switched the lines around, put on the new couplers, now she works great! Thanks guys!
