where you using a backhoe without a subframe?
The Backhoe is a New Holland 758c with a subframe. The problem that I see with the TC30 design and a few other New Holland machines is as follows.
1. The tractor has no subframe tying the back end to the front.
2. Very thin casting on the bell housing where 80% of the stress is placed when using the front end loader or the backhoe.
3. The motor and bell housing do not mount up flush with a complete circle. Instead the motor has two small ears with two bolts per side. The rest of the circles mounting surface is thin gage metal.
I walked through my local Kubota dealership and saw just the opposite on every Kubota tractor. I saw full cast to cast mounting surface where the motor and bell housing meet. I also saw full steel frames tying the complete machine front to rear. Hate to bash New Holland but after seeing that my next machine will be orange
Oh and don稚 think this issue is limited to only the TC30. I saw quite a few other models with almost the same design. The new Boomers seemed to have a bit more frame so maybe New Holland is figuring that the design is bad.
As far as the comments go about not using your tractor to dig with a backhoe attachment. To me that like buying a new truck with a factor towing package and the dealer telling me after the hitch breaks in two pieces the truck wasn稚 really made to tow. You should have bought a Semi if you wanted to tow something
A friend of mine owns a body shop and does a lot of frame work. He is going to build me a subframe. He said he may be able to build a few if there if there is some interest. If you are interested PM ASAP so I can tell him there is interest in building a few of these.

The issue sounds like the lack of a GOOD quality sub-frame that accepts the full stress from the hoe. Even then, it will still eventually crack something. Hoe's always crack something eventually.
Mine broke but I fixed er good
Where the loader arms attach to the transfer case/ bell housing, there were 1/2" thick spacer plates between the quick detach arms and the casting, the assembly was additionally stressed by poorly designed backhoe support brackets. After I welded the bell housing casting cracks with stainless rod, I manufactured a pair of 1/2" thick steel plates to replace the spaces and bolted them to one another with 3 - 18" long 3/4" threaded rods. This literally clamped my repair together and strengthens the right loader arm to the left one :thumbsup:
This is a highly recommended modification if anybody has a little backhoe tractor
...& obviously even better if you install them 'before' you bust yours like I did mine

Count me in on the lawsuit. Repair picks would be nice if anyone wants to send me some. Thank you
Sounds like he has a three point hitch, after market backhoe and had the rear wheels off the ground. The rear end of the tractor twisted when using the back hoe which stressed the weak point on the tractor, the point where the front and rear connect together.
A gentleman with a lot more tractor experience than me told me one time if using a backhoe on a compact or subcompact do not lift the rear wheel off the ground with the backhoe stabilizers. His theory being when using the backhoe you will twist the rear of the tractor because the rear wheels being off the ground can twist and move. The front wheels plus the loader will hold the front stationary and prevent movement and something has to give.

At this point it's a 20yr old tractor so if there was going to be a lawsuit it would have alreaty happen. Every tractor manufacturer has ones that break in half.
