Industrial 40 backhoe attachment

[J Bailey]

I have a mf 40 with a backhoe and loader. The backhoe was detached when I got it and had been for several years. All the hydraulic hoses for the backhoe supply have been removed. my question is where do I get the supply from and where does the return connect. any help would be appreciated.

Hi, It may help someone to know which model B/H
as more than 1 model was sold for this machine.
The tractor, loader, and backhoe each have their
own model and s/n. Should be a black and silver
rectangular metal plate with this info on ea machine. Chuck

on a MF35 industrial, front pump feeds the loader controls, unused oil dumps directly into right hand side frame, oil returns to filter/front pump thru a large hose

if backhoe is attached, a special plug is inserted into the bottom of the loader controls and hose runs from this plug to the rear hoe controls, unused oil runs back into loader frame thru a fatter hose usually plumbed near your right ankle

have seen 2 versions when hoe is removed:

easy - the 2 hoses going to rear are simply connected together and are always in the way

neater - both rear hoses removed and return is plugged off, special plug on loader control is removed and original plug is inserted, no hoses in the way but you have to find that special plug and those hoses to hook the backhoe up again

The info is well explained in the operator's manual, available from AGCO. Ours uses quick disconnects at the end of the tractor hoses, one plumbed as female, the other as male and when the backhoe is off you just plug the two hoses together as the oil must still be able to flow. I have them looped over a hook attached to the right fender, when they're hooked together (backhoe off).

Thanks for the replies. I put a high pressure gauge on the loader control where I thought the pressure should come from and only had about 20 lbs. If this is where I should be getting high pressure what would cause low or no pressure.
The loader works great so I don't think I have a pump problem.
Thanks again for your help.
