Need educated on 3 pt backhoe attachments.

I have a 3PH backhoe that I have had for about 6 years. I don't use it a lot now but used it for most of the first 100 hours on the B7610 I had before. It doesn't simply hang on the 3PH, there is a small frame that bolts to the drawbar with large turnbuckles, similar to the adjustable top link turnbuckle, that go from that frame to the BH. Adjusted correctly you have the top link under compression rather than tension so unlikely to stretch bolts and/or threads in castings. This way the drawbar carries a good deal of the weight of the BH too.
I bought the BH from the dealer I bought the tractor from. I asked them about possible damage from the 3PH mount, having read about it on this forum. The only tractor they had seen damaged was one where a carrier had chained the BH bucket to a trailer when the BH had the transport lock on so the bucket was off the trailer deck then took off down a rough road. The bouncing of the tractor on its tires with the bucket chained down caused the damage. They did not 'know' of any tractor that had been damaged while digging witha 3PH BH.
If you tend to break things then a subframe is the better choice, IMO. If you operate with some finesse and don't just keep pounding on things until something gives then the 3PH style will give you years of problem free service.
This is my experience and my opinion based on that experience. I don't doubt that tractors with 3PH BH's have been damaged but so have tractors chained to stumps.

Brandoro, I'll have to agree with you. I've had a small 3-point backhoe attached to my Kubota L245DT for several years now. I don't mistreat it because it clearly can put stress on the tractor. Of the pictures I've seen of tractors broken in half with backhoes, it appears most, if not all, were broken while driving the tractor down or across a very bumpy road or field. My guess is that most of those owners would have destroyed their tractors in just about any manner given enough time.

I hear one of the best ways to break your tractor in half is to throw a chain over the middle and crank it down to a trailer.

I should have bought a mini excavator instead for the money, mine is sub frame mounted very strong, I am an equipment operator, and operate several machines

to add more digits to the "broke my tractor" there are several posts about breaking a Kubota 2800 on http://www.********************.com/review/Kubota/L2800.aspx, and looks like at least two authors.
