    Default NH Or Case 757C Backhoe Owners

    Hi guys. I've been looking for a used backhoe for years to put on my 2001 NH TC33D. I definately have uses for one, but not enough uses to justify buying a new one. I finally came across a used Case 757C that I'm told should fit just fine on my TC33D. I am purchasing it from a Case dealership and I talked them into installing it for me. I have an appointment next Saturday (9/25) to bring it in.

    The Case dealership said it will run of my rear remote that I normally have hooked up to my hydraulic top link. When I later called my NH dealership they agreed it should be able to run off my rear remote, but they said I would probably have to use a bungee cord to hold the control lever for my rear remote into position.

    I'd rather not have to use a bungee cord, and I want to make sure I'm not doing anything to damage my hydraulics. The Case dealership doesn't have the manuals for the 757C, but it looks like I can order them online directly from Case. I already purchased and downloaded the PDF version of their owners manual, but it doesn't really cover installation.

    I can order the installation manual for the backhoe subframe, but that only comes in print version and I don't know that I would get it before next Saturday. So I thought I would ask here to see what you guys know about hooking a 757C up to a Class II Boomer.

    The preview image shown on Case's website of the subframe installation manual refers to hooking up a hydraulic kit to run the backhoe. The diagram refers to "power beyond". When I asked my NH dealership if I could get a hydraulic kit or power beyond kit, they said my loader joystick is already hooked up to my power beyond port. They said I could convert my steel high-pressure return line from my loader valve to a flexible hose with a quick-disconnect and then when I wanted to use the backhoe I would disconnect that flexible line and use it for the backhoe, making my loader inoperable. He said I wouldn't be using the loader and the backhoe at the same time anyway.

    So what's the real scoop on running hydraulics for the backhoe? I don't want to spend a bunch of extra money to have the optimal hydraulic hook-up for it, but I don't want to have an inconvenient way either. Most of all I don't want to do anything that could potentially damage my tractors hydraulic system.

    Thanks, Spence

    You can power the hoe from the rear remote without any problems or damage potential. You will need to bungee the remote valve control lever in a stroked position.

    You can also use the more typical power beyond style installation that the NH hydraulic kit will provide. You will get nearly identical flow and pressure from either installation.

    If I were you, I would run the hoe from the rear remote without question. Easier on/off, cheaper; no downside.

    What we need is more idiot control.

    Thanks Rick, it's good to know just hooking it up to my rear remote is fine. I searched for other threads here and in a few of them there is talk about the 3-point hitch arms possibly being damaged or damaging the hoe. Do you have any comments on that subject?

    Personally I would find it a major pain to have to connect and disconnect the loader and backhoe hydraulics. I use both all the time. Have to use the hoe to dig because the tires dig better than the loader does. And I use the bucket to steady things when using the backhoe.

    Nobody is suggesting it is necessary to disconnect one to use the other.

    I was responding to that.

    OK. But the guy that gave that advise didn't know what he was talking about. A proper installation of that nature removes the steel line leading FROM the loader control valve, not TO it. loader function is not interrupted when this installation is properly done.

    Hey Guys, I have a TC33 and just got the NH 757 backhoe attachement. I'm trying to figure out what I need as well to get things going. It looks like I need a rear hydrolic kit. Do you guys know what that kit is called or where I could get it? I'm looking for any advice to get things hooked up and running as well as possible.

    Another link that is along the same line as the one Rick posted :

    http://www.tractorbynet.com/forums/n...d-backhoe.html

    Mine is a Factory N.H. install , Pretty easy to install B.H. and the feature I like the most is that it Disables the rear 3 point arms , thus if tractor is used by others , B.H. or 3 point cannot be harmed by inexperience .
