It certainly isn't the fault of the tractor, it is simply misapplication. In my opinion no tractor should be equipped with a loader without first ballasting the tires unless there is a good reason not to (ex, a machine that will be used mostly for turf work with the FEL off). Nearly all of your stability comes from your solid rear axle. Loading tires isn't costly and the new organic liquids developed specifically for ballasting (Rimguard, Citrastar, beetjuice, etc) don't eat the rims up like calcium chloride did. If you have R4s on your MX, a 3/4 load will add about 450 lbs to each tire and that will make an enormous difference in your stability, both for the loader and for side hills. Additionally if you are going to be doing a lot of really heavy loader work, make up an adequate 3 point counterweight. I usually max that at about half of what the loader will lift at BC to full height, in your case 8-900 pounds. Counterweighting has the addition benefit of transferring some of the front axle weight back to the rear axle and will provide a lot more traction as well as stability.
Over the last few years I have built roughly 1 1/2 mile of road on my very steep and in some areas very soft New Hampshire property using my L5240 equipped with a Woods HD bucket. That bucket will hold a little over 1/2 yard heaped. My preferred base material is 3-6" granite ledgepack which weighs in at about 3000# per yard if its relatively dry. It's heavy and tends to bind together which makes it difficult to dig into, but my well ballasted tractor does this easily, and so would yours if it were set up similarly.
Learn from Kubomans good advice too, the pickup point leveraging is critical. Even with the extremely light counterweighting of your tiller you might have been able to handle that furnace by wrapping your chain off the inside of the bucket rather than the outside.
Finally, and hopefully your dealer emphasized this during your training, if you find yourself in danger of tipping, ground your bucket!
Don't be discouraged, the tractor you have chosen for yourself is a performance monster and will do all you likely ask of it ...once you get familiar with it :thumbsup:

A bit of an addendum to my previous post...I'm assuming (could be wrong) that CJBOTA is new to tractor ownership.
If that's the case..well, when first operating a machine as tall and top heavy as a tractor...they always feel like they're going to tip over...even driving over a small bump. That's part of the learning curve...but always have the ROPS up and seat belt nice and snug (just in case...)

Another thing that can help (besides filling the tires) is widening the rear wheel track (width between the rear tires).Not a Kubota owner, so I don't know if you can just reverse your wheels, swap 'em side to side or you may require spacers (apparently, from what I read on TBN, spacers are necessary on some Kubotas).

That is very often the case, what "feels like" a near roll over may not even be close and will vary between individuals. I have seen my son do stuff on our tractors that would scare me to death and he has never put anything on its side. I am not particularly uncomfortable with a back tire a foot or more off the ground under some circumstances, but certainly don't recommend it.

Different wheels on the different models, so it's hard to tell, on a couple of ours, you can unbolt the center dish from the rim and use several configurations while on some it is solid. We have all of our wide; not too familiar with spacers beyond the BX and B.

Very valid point on HST operation, I missed he was a new HST operator.

The smaller Kubotas are pretty light in the rear. On a tractor that size you need 1) fluid filled tires, 2) wheel weights and 3) extra ballast on the rear to really get full use out of the loader. IMO Kubota puts a little too much loader on some of their models.

My B3200 has fluid filled rear tires and usually a 400-600lb implement on the back for heavy loader work. Provides all the stability I need. A tractor the size of an MX5100 you need a 1000-1500lb implement on the back. I will say that the M9540 we have at the farm is pretty well balanced without anything on the back. It does have cast rear wheels and fluid filled tires however.

This is my set up . Wheel weights and 900 lb.s on back easy on easy off when I don't need it.

My tractor is front heavy. With the loader and nothing in the bucket, the rear end was very light. When I tried to backup on a very slight incline I had to uise 4 wd. The box blade I have weighs 759 pounds with the weight I added, two steel plates bolted on and six 42 lb suitcase weights. There is no way I would I try to lift anything without the box blade on the back.

One thing I've noticed...if I'm operating in a low gear (very low ground speed), the changes I feel in the slope (less the 10 degrees) can really give me a queasy feeling...the same area in a higher gear (higher speed) doesn't bother me near as much...even though I would think the higher speed would be more dangerous.

BTW, I'm one of the safety freaks...ROPS up, seatbelt fastened at all times.

What model is your tractor and what are the wheel sizes.:confused:

Roy, for me I have found a lot has to do with the particular tractor. Things that scare me on our 5030 or use to scare me on our CX 80 won't on the 8540 and I have never really been concerned with our old Massey Ferguson 375, it is the most stable and stable feeling tractor I have ever driven. It is also the style where you straddle the center hump with fender immediately to each side.

I "imagine" in most case the higher speed would be more likely to tip you, but sure know the whole perception v reality often don't make much sense. Heck, I feel more comfortable with one side down hill than the other and when I was young and rode motorcycles pretty fast, I would take a fast right hand turn with more ease and comfort than a left hand one. And the same thing on my dirt bike on flat land, but preferred a left hand uphill turn to a right one.:laughing:
