Backhoe 3pt vs. frame mount backhoe

[MtnViewRanch]

I've heard alot of talk about there being problems with the 3 point mount, but have yet to see anything more than talk. I had a 3 point version on my b7800 wuthout any issues. That being said If I bought another one I would probably get a subframe version.

Go over to the Montana forum, there is a guy over there now that has had problems with his 3pt mount back hoe. Something about bending the mount for the top link. A link to Montana forum. http://www.tractorbynet.com/forums/montana/141012-i-broke-today.html

That's still a far cry from "Breaking a tractor in half" There was someone else on the same thread who broke their top link with no mention of a backhoe being involved. I still think it's pretty isolated.

The only reason that I posted was that you said that it was all talk, and that you had not seen or heard of any actual instances. I didn't see where you were looking for a tractor broken in half. If I had known that was what you had meant, I would not have posted, sorry for the inconvenience.

I am guilty of the top link breakage.
My fault, I didn't have the diagonal brace attached and was over pulling. Reaching down on a stump, this I was lucky with pulled the flange right off the base. I was not well to learn he part was 79 dollars. But If it had been the casting. ..OMG
But with it properly attached, I haven't had any troubles.Just treat it with care.
I do remember one case posted here with the top of the casting torn off. Id prefer to think of the steal bolt on flange to the casting as almost a shear pin.Rather have that rip off first
BUT again I was mostly at fault with the brace not locked in,I actually altered the brace so it can be disconnected easily and the hoe can raise higher up for clearance..But there is consequences if I don't lock it back down.
Good Luck,,,,

Well I called a local dealer and they quoted me about 8K for a Woods 7' with 4 point attachment (like the Kubota BH's), a thumb and 2 yr warranty for a B7610.
Now the question I've got is can I use it on a bigger tractor when I'm ready to move up?
The backhoe is going to be worth more than the tractor.

I might be out of touch a little, but I thought that the B4672 Backhoe for the B7610 is only available in 3-pt mount. I've had the 3-pt 4672 hoe on my B7610 for 5 years with no problem. Regardless of all the horror stories of cracked cases and tractors split in half, the 3-pt BH is one of the reasons why I bought the Kubota over the New Holland. I use a mid-mount mower and don't want to remove a subframe to get the mower on. The New Holland dealer checked with the factory and they told him that it would take 2+ hours to go from MMM to backhoe! Granted, it sometimes takes me a half hour to put the loader on, take the MMM off, and put the backhoe on, but at least it's not 2 hours with me laying on my back underneath the tractor.

An important thing to keep in mind with the Kubota 3-pt hoe is that there is a special, hardened pin for the top link that must be used. Don't get this mixed up with the standard top link pin or it might break.

In my experience, the 7610 is solidly built and is able to withstand the 3-pt hoe. Just keep everything snug (link arm turnbuckles). The tractor is too light to use the full power of the hoe, as it pushes or pulls the tractor before the hydraulics stall, so I don't think you can get enough force into the tractor to break anything.

Interesting, Dave. I'm going to call up the dealer where I got the hoe and ask about that hardened pin. Thanks.

Concerning the pin,
I remember getting a 'special pin' from the dealer with it. That was 25 years ago.I was younger then and didn't give it much though
so ever since, its been whatever pin I have around .
Personally, I would like to believe the pin could deform and break before the casting. Like a shear pin..
I know when mine tore free it was with the pin that came with my rake. so it was strong enough to withstand that pressure

Well that may be true for the Kubota BH. but these are Woods. I went to another Kubota dealer and he was going to sell me the same thing - a BH70X w/ 4 point attachement. But now I'm looking at a BH6000 used, but again with 4 point attachment.

Dave -
From your post it seems you are pretty pleased with your combo.
The one dealer told me the BH70X (~$7K) would be to big, and to me the BH6000 (~$5K) looks a little small.
Then he said there were still some B4672's in stock. And they are going for about $6K.

Looking at the specs for the BH6000 and the B4672 it seems that the B4672 has a significant increase in digging force w/ the dipperstick (1740 lbs) over the BH6000 (1180lbs).

Of course the BH70X is even higher, at 1 ton.

Do you think your B4672 is actually that much stronger than a BH6000? Most of the other specs are about the same.

One of my main things will be digging up stumps.

Any advice appreciated.

Itchy credit card.

I have a MF1529 and was wanting to put a BH on. Has anybody had any experince with a 3pt BH for the 1529 or similar models. I only heard of the bad, but if companies are making 3pt BH, there has to be something good? I would like to hear mor from folks who has 3pt BH.
