Case backhoe on JD2010

[05victorylly]

I posted last week about picking up a loader backhoe, and I talk to my uncle and he said I can have the backhoe that was on his case 450. I guess one of the cylinders is busted so he stopped using it. So now I am considering putting that on my 2010.

It was mounted on a case 450 of similar age to the 2010. It looks like my 2010 has the mounts for a backhoe on the rear, but I have not measured yet to see how different they are from the case. They are the same style mounts, just not sure on the measurements.

He has a parts machine (case450) that has the backhoe frame on it that I can take, so I figure I can do some cutting/welding to make the case frame mount to my JD backhoe frame.

I know it will take a little work, but I am getting the backhoe for free so I figure its worth the effort. Worst case I can take the frame to a prof. welder to do the fabricating if I don't think I am up for it.

You guys think I am crazy or does this make sense?






[color=red]UPDATE:[/color]

I snapped a few pictures of the backhoe. The mounts will work, just need to do some cutting and welding.

The main issue is that the boom cylinder(think its called that) has a large crack running all the way down the length of the cylinder. I assume this means I need a new cylinder...there is no way that can be repaired, right?

Here you can see the crack in the boom cylinder(the one that lift the main boom):

that mount that is on your 2010 is a ripper/weight mount the hoe bracket is longer but you can make what you have fit what you want to put on it the one main thing you need to find out is is the 450 case hoe a closed or open center valve? 2010 is open center i believe.... yes you can use it if the hydraulics match i put a Massey 205 hoe on an old 300 case

If you don't mind explaining, what is the difference between open and closed center valve?

EDIT : just read up on the difference.....guess i need to figure out if that backhoe is set up correctly for my machine.

For the hydraulic fluid to do work, it must flow to the actuator and or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types. Open center circuits use pumps which supply a continuous flow. The flow is returned to tank through the control valve's open center; that is, when the control valve is centered, it provides an open return path to tank and the fluid is not pumped to a high pressure. Otherwise, if the control valve is actuated it routes fluid to and from an actuator and tank. The fluid's pressure will rise to meet any resistance, since the pump has a constant output. If the pressure rises too high, fluid returns to tank through a pressure relief valve. Multiple control valves may be stacked in series [1]. This type of circuit can use inexpensive, constant displacement pumps.

Closed center circuits supply full pressure to the control valves, whether any valves are actuated or not. The pumps vary their flow rate, pumping very little hydraulic fluid until the operator actuates a valve. The valve's spool therefore doesn't need an open center return path to tank. Multiple valves can be connected in a parallel arrangement and system pressure is equal for all valves

i am putting a 480c case hoe on the back of my 2010 loader soon

[05victorylly]

Excellent description, I understand. I'll have to do some reading on the case backhoe's and see if they are open center valves or not.

[05victorylly]

So assuming the backhoe is set up as an open center valve what will I need to hook up the hydraulics?

I assume the return line can just be T'ed in and then I will need a diverter valve on the supply side to divert the flow to either the loader or the backhoe.

I have this Case backhoe that fits nicely on the 350b in the photo. It has a custom made bracket that fits onto the Deere and except for the slightly different size looks very much like a Deere bracket. One draw back is that I have a Deere Ripper that will not fit the bracket. It is easy to install, and after some practice, I can now do it easily in 5 min. I have heard that the hoe is quite good and possably less trouble than the Deere. I have not used it much but this summer it will have jobs to do.

What model is that backhoe? Any pictures of the mounting brackets?

[Scottyb]

Model D130 I think it came off a Case Uniloader. The bracket is off but still under 4 feet of snow. I could take a few picks for you when it melts a bit here.(I had 4 rounds of golf in by this time last year)

Did you make the mount or did someone else make it for you? Or was it something you got with the hoe?

[Scottyb]

It was custom made by the previous owner. Almost identical to a Deere bracket but with the mounting dimensions for the case hoe. I took it off of my 350b and installed a winch and arch on it for logging.

Since then I have bought a 350c with a ripper but unfortunately, I cant use the two attachments on the Deere bracket. So, I am seeking a Deere bracket for my 450b then move the ripper to it, and put the Case hoe back on the 350b, and the winch to the 350c.

I could dig in the snow this week end and try to get you some photos of my Hoe bracket however it looks from your photos of the 2010 that it would mount differently to the crawler.

I appreciate it, but don't go out of your way. I figured it may be sitting outside (not covered) or in a barn so it would be easy.

My uncle has a parts machine (case 450) with the mount so I should be able to salvage parts of it and parts of my 2010 ripper mount to make one case/deere backhoe mount.

I just need to make the trip up to his farm to assess the condition of the backhoe, its been sitting for 15 years.

Anyone know how to figure out if the hydraulic valve on the case backhoe is an open or closed center?

Its parked out in a field, so I need to do this with some what limited acess to tools. Not like its sitting in the shop.

[Tigerhaze]

Identifying the backhoe model may not a reliable indicator of whether it is open or closed center, as some models can be configured for either setup depnding on how the valve block is plumbed.

However I would think you would be able to tell by looking at the hydraulic setup of the Case crawler and tracing the lines on the crawler for the hoe connections to see if they form a continuous loop to the hydraulic reservoir. if you can figure out whether the crawler is set up for open center or closed center, then the hoe attachment will be the same, assuming they formerly operated as a set.

There have been some discussions in the past on using a non-Deere backhoe on a Deere crawler and identifying open and closed center setups- if you search the board archives you can find them.
