Does the Mahindra BH need an under plate on the tractor to work? This would prevent the tractor from twisting in 1/2.

You can make anything fit with time and steel. You'll want to make a sub frame to hold it together. I would make it so that you use the stabilizers would pick it up and use bucket to push into place on mount. Don't rely on the 3 point to hold it. I put a Mitsubishi loader on an Iseki.

yes it does, it has a subframe, that goes to the front,

shame to see that machine abused like that

This reply to my post is because the pictures came from my tablet which is really hard for me to type on, so I am now posting from my computer.
I'm not sure if this backhoe is still available but if it is I am thinking I could adapt it to my Yanmar YM2310. The backhoe was sorta frame mounted to the Mahindra tractor. The mount was not a 3 point. There were instead plates welded to the tractor frame. These plates had hooks cut in them at the factory and the hoe was captured by them. I'm not sure what the top of the hoe connected to but the seller has these parts too. The seller cut these plates and the mounts from the tractor and they come with the hoe. The hoe weighs less than 1000 lbs. I think.
It is powered by the tractor hydraulics. I will instead use a PTO pump and reservoir. I do not like dripping oil every time I take the thing off. I know, it's not much. The seller told me it's about 1/2 cup, maybe a little more, whenever he mounts or dismounts the hoe. He told me I cannot dig stumps out with the thing. He has 2 excavators that he uses for jobs like that. He got the tractor, complete with hoe, tiller, and other stuff as part of a trade for work done for a friend, so I don't know how many times he has connected or disconnected the hoe.
I already have a Case 580CK. It is great for digging big stuff. But not so great for tight spaces. Anyway, I have posted about this before and have read all the comments. So the real question is: can this backhoe be used on my Yanmar? Is it practical to adapt it? I am a retired self employed machinist and I still have my complete shop. So I can fab a frame mount. The hoe just has to fit.
Besides the PTO mounted pump I will also need a reservoir. I think that the reservoir does two jobs. It holds the hydraulic fluid and cools the hydraulic fluid. I thought about using a 20 pound propane cylinder but it may not have enough surface area for proper cooling. I also have a steel scuba cylinder that's about 8 inches diameter and 30 inches long. And I have some .060 thick steel sheet that I could bend and weld into a large surface area tank. I don't know how many gallons I would need to keep everything cool.

I would need to build a subframe. The parts the seller cut from his Mahindra I would weld to the subframe. The subframe would bolt to the FEL frame and the rear axle. The FEL frame attaches to the tractor on the engine side of the bell housing. So when digging the force would tend to rotate around the rear axle and push up on the FEL frame. So the forces would tend to push the tractor together. I'm not sure about the forces when pushing up with the hoe.

Which machine are you talking about being abused? The Mahindra? Or the proposed Yanmar YM2310? If the latter please elaborate. I don't want to abuse my tractor. If a suitable subframe can be built, one that doesn't stress the tractor beyond what the factory considers acceptable, is there a reason why I shouldn't do so? Please keep in mind that Yanmar built a 3 point backhoe that would fit my tractor. Also, please understand that I am totally serious and so are my questions. I don't want to abuse my tractor and I won't abuse folks who reply to my posts.
Thanks,
Eric

I was talking about the mahindra, there are bolts missing in the pin on bucket, etc.

I have no idea what this guy is talking about welding anything, the mahindra kit is a bolt on setup, for the backhoe, there are 0 welds in any portion of the machine, the entire subframe drops down

clearly you would need to modify it to fit your machine, but when people make comments like it was welded, had to be cut off, NO, no it doesn't, which makes we wonder what he is doing.

I considered getting a backhoe for my YM226d. Someone at the time told me they had seen a lot of tractor rear ends broken by backhoe attachments. So I didn't buy one and am still using my beloved 226d. I did find a Terramite. Even though the Terramite was purpose built to use as a small backhoe and weighs 2700 lbs (more than my Yanmar), I've had to weld up stress cracks in the Terramite frame. When I was servicing one of the front axle bearings recently, I noticed that the front axle had been broken and re-welded by a prior owner.

Maybe the seller doesn't know that the subframe can be unbolted. He showed me the plates that he cut off and where they were welded to his tractor. I saw where the plates were attached. He is supposed to be around on Saturday so I will try to get a few more pictures and then post them. He had a bunch of stuff piled around the hoe so maybe the missing pin is there too. The plates he cut off had hooks cut into them for the backhoe. He told me the reason he cut off the plates was because they interfered with the arms for his 3PH. If those plates are indeed part of a subframe that can be unbolted then maybe I can point that out to him and get those too if I buy the thing. I would love to have a complete subframe to modify rather than just the two plates he cut off.
Thanks,
Eric

he butchered the machine.... the 3 point hitch works perfectly, with the backhoe subframe on, it wouldn't make sense for it not to.

I wish you luck, he clearly did not know what he was doing.

The backhoe looks to be in good condition and he will hook it up and operate it though it will of course just be the hoses connected which will limit the kind of tests I can subject the hoe to. If I do buy it I will want to operate it from a PTO driven pump. Do you see any problems with that? Also, do you know if a hydraulic thumb is or was available for this hoe?
Thanks,
Eric

 

[LittleBill21]

no I have never seen a hydraulic thumb for it, that one appears to be the factory thumb kit.

this hoe was run off the loader valve in the front.


issue with the pto pump is room, the farther from the back of the machine the more stress you put on the frame, there is nowhere near enough room on the mahindra to put a pto pump and run it with the hoe on, you would probably need to add a foot

I see you have no existing hydro lines, sorry

 

[Topzide]

I agree that a pto pump would push the whole unit to far back. Since you still have your tools, could you make a manifold to pull hydraulic from and then return into trans? This is what I had to do with my Iseki when added FEL. Also made sub frame from front back to rear axle. Did this with a Porta band, 4.5 angle grinder and tombstone ac/DC welder. With your shop, should be a breeze and would hurt the tractor as long as you know it's limits. You right about getting into tight spots! My buddy put a Kubota BH on his Iseki. If price is right, pull the trigger!

 

[etpm]

I'm not sure that adding a pump that hangs off of the PTO will be a problem. After all, the PTO shaft is permanent, so it will always be there. And the pump will only be sticking out 1.5 inches farther than the shaft. On the other hand, I have never done this, adapting a Mahindra backhoe to a Yanmar tractor. This means that I need to take any advice or suggestions seriously. And I will. LittleBill21 brings up good points and I would be a fool to not pay attention to what he has posted. For example, the pump hanging off of the shaft takes up a lot more room than just the shaft sticking out of the back end of the tractor. It has width and length. So instead of a shaft that is 1 3/8 diameter and 4 inches long there would be a pump that's 7 inches wide, 9 inches tall, and 5.5 inches deep. Much Thanks to everybody who has posted advice so far, I really appreciate it. This coming Saturday I will be taking another closer look at the hoe and hopefully make a decision whether to buy it, but the price will need to be adjusted downward based on what I have read so for.
Thanks Much,
Eric

I really would rather keep the hoe hydraulics separate from the tractor and I think I can do this but will still need to measure stuff. Anyway, the seller returns to the island Saturday so I will be able to look again at the thing then.

Thinking about this a bit more, my experience with the Terramite has been that the backhoe bucket pushes the entire machine around and doesn't dig worth beans unless I first raise the entire machine off the ground using the front bucket and outriggers. 2700lbs alone isn't enough to keep the machine from being pushed around by the backhoe and even fully raised onto the outriggers and front bucket, the backhoe bucket will still push the machine around a few feet or so when trying to dig in hard ground.

I mention this to ask if your Yanmar has a front end loader?
