Backhoe options for a 2010

[magnus]

I recently found an add selling a 9200 model detachable backhoe. They are saying that is for a 450b/c. I really don't have much info on the other JD models wondering if this might be a go for my 2010 crawler with 820 loader.

What kind of modification it may take as well.

The 2010 originally could be paired with a Model 50 (center of tractor) or Model 51 (slider) backhoe- both weighed close to 2500 pounds, used a rotary swing cylinder ("dougnut"), and operated with open center hydraulic systems.

Someone on here will probably be able to definitively answer your question about a 9200 (which I am not aware of and don't have a spec sheet for), but generally for compatability you need to verify the following:

-the attachment points for the backhoe (pin mounts) fit the hooks and holes of the 2010 hoe bracket
-the backhoe is an open center hydraulic system and will connect to the quick connects hoses on the 2010
-the weight of the later backhoe is not significantly greater than a Model 50 or 51- as it is a Model 50 is quite a bit of weight on my 2010 and puts a lot of weight on the rear especially on slopes

I think (needs verification) that the 450B crawler is also open center, so if the hoe was on a 450B then it should be hydraulically compatible with a 2010. If the hoe is closed center, you could stall the engine, blow your pump, or worse.

Apparently some of the later hoes can be converted from open to closed center and vice versa by switching valve blocks as discussed in this post:

Modifications of the attaching points and hoe connections can be made- several on here have adapted hoes from different manufacturers to JD crawlers so that is not impossible.

Hope this helps

I hope someone can help with this post. I will be looking for some help with the same questions. Of course that is when I figure out what model hoe I have. I do know its of a 450, but thats all the info I have. The tag is beat up and I cant read the numbers. I got what I think is an incredible deal on it, but may end up needing to sell it for the correct unit.

Hi guys-

There are a number of threads in the archives which discuss the cosmetic and mechanical differences between the various hoe models- if you read them they will help you with your dilemma. FYI, one of the thread discuss how you can identify an open center versus closed ceneter system by looking at the valve block arrangement.

Here are several (but not all) of threads discussing the various models of hoes:

Feel free to ask more questions, but it is easier for us if you have read the previous threads first so we don't have to repeat ourselves

Thanks for the links, I tried the search but it seamed like I was getting the same threads no matter what I typed in. Thanks again

Had my wife try to read the id plate on my hoe (it's pretty beat up, and she can see a little better than I can lol) this is what she got "EG0093 - G10694U", am I right in assuming it's a 93, or is it a 93A?
If it is, can I just plumb lines in for the quick connects (1 pressure, and 1 return) and be good to go?
I am still confused about wether my 2010 is open or closed center, and if the hoes is open or closed. Also, am I going to need a "bypass valve" to run it? I'm not sure if it is actually called a bypass valve, but a 450 I went to look at for a friend had one, and the owner said you have to pull it up to run the hoe, and push it down to run the blade.
To sum it up, can I just add the pressure and return lines and ne ready to dig? Thanks ahead for any help.

The 2010 crawler loader is open center- the quick connect hoses on the rear of the crawler cycle the oil through the system until connected to an attachment.

The 2010 loaders set up with the hoe bracket and quick connects do not need any bypass or power beyond valves- simply disconnect the hose couplings and reattach to the hoe (while the machine is off) and you will be good to go. I'm assuming you have a rear mounted Cessna pump on your 2010- the quick connects are just above the pump on the top of the hoe bracket.

I am not sure about your hoe ID- someone else will have to weigh in on that. However you shopuld be able to tell whether the hoe is open or closed center by examining the valve block and how the hoses enter it as described in this thread by KenP and MattE:

I tried the search function with no luck again. What I am wanting to know is which hose is in and which hose is return on a 93 hoe. I guess as if I were on the seat using it. I took off the old quick connects and dont remember which was which. Thanks for any help.
