3-Point Hitch Top link mount tore off back of differential case

This is the kind of situation where the money transfer apps provide a decent service. A bunch of people could kick in a $1 and this expensive proposition could be rectified with little impact to anyone's wallet.

^ thats actually a pretty good point, coldsteel. I'd chip in a few bucks if you set up a gofundme. They are easy to make, OP.

Is that axle housing made of cast iron, aluminum, ??


I've had a Kubota 3-point backhoe since 2007. Primary use is taking out orchard stumps including prying on the stump. The manual for this K-650 backhoe (4/79, published by Kubota) shows it on a Kubota L225 (20 pto hp) so it is a good match for my YM240. (American Yanmar 1980, 20 pto hp.)

Soon after I bought it, it caused a trivial repair, slightly bending a 3-point arm trying to drag the tractor sideways to re-position. BFH over an anvil straightened that.

And the BH did cause one major repair that wouldn't have happened if this tractor had been better maintained by prior owners: When I bought the Yanmar well-used in 2003 I noticed a 3-point lower hinge pin was sloppy loose where it went into the axle housing. I reset it with red (permanent) Locktite and forgot about it. 15 years later that hinge pin worked loose, I didn't notice, and the BH ripped the pin out of the axle housing. $500 repair. My thread describing this.

The L series have cast iron/steel housing, I'm really curious to hear what the conditions surrounding the actual breakage were.

Maybe what you are seeing is sub frame mounted hoes....Massey Ferguson make 4 model of SCUT, the 1705 and 1715 do not come with BH, the 1710 and the 1720 DO come with sub frame mounted BH... Its really not the size (different issue of "work" capable ), but how tractor in manufactured where it may be capable of BH or not...

Dale, thanks for the education. I have a lot of small trees to clear and I played with getting a BH for my new LS but the cost was more than I could justify.

I want to add a thanks to the OP for sharing this as I have learned a lot.

Just wondering...could a person mount a SSQA plate onto the 3pt hoe and run it on a skidsteer? :confused3:

Yup, a lot of aftermarket manufactures even offer that as an option, other then the Chinese BH most have a couple mointing options (3pt, ssqa, subframe).

Shouldn't Woodmaxx be on the hook here somehow? This isn't the first and they MUST be aware of the problem. Seems like they should have changed the mounting system and provided some extra support hardware.

Caveat Emptor....

Looks like the Woodmaxx hardware survived... Why would it be their problem...

WOW! I really feel for you. That is about as bad of a thing that could happen to a tractor. Thanks though for point out a non-hypothetical problem of having a 3 point back-hoe.

On the closeup pic, that rusted, tapped hole is concerning. Just speculating- not likely water could get down in there on a tightened bolt. Loose bolt would completely change the stress distribution on that assembly.
