- lots including Kubota B's, L's, cat, etc.. over many years
no trouble with either.
both are approved for rear ballast just not at the same time.
both are ok individually. Together exceeds what Kubota approves as per the operator manual.

I'd say it depends on how a person operates the tractor and hoe.
There's no doubt a filled or weighted tire held out on the end of an axle has the potential to put a lot of bending stress on that axle - especially when the stabilizers are holding the tires up off the ground. Then add momentum to the bending stress as a heavy-handed backhoe operator bounces the machine around, and it isn't hard to see why Kubota recommends against weighting backhoe tires.
A buddy of mine does odd jobs, renting backhoes and mini excavators as needed from the rental yard. Watching him at work with a hoe you'd think he is riding a pogo stick.
Maybe someday someone will make a video of him working a hoe; for now we just grab a beer and watch the entertainment. It usually doesn't take long....

I asked AI about the issue and this is the reply:
AI Overview
It is not advisable to have filled tires on a tractor with a backhoe attached because
the extra weight from the backhoe combined with the fluid ballast makes the machine excessively heavy, leading to increased soil compaction and ruts. This can also negatively impact maneuverability and cause a rougher ride, especially on roads, while making tire maintenance more difficult.

Key reasons to avoid filling tires with a backhoe attached:
- Excessive weight: The backhoe already adds significant weight. Adding liquid ballast to the tires creates an overly heavy tractor that is prone to ruts and soil compaction.
- Maneuverability issues: The combined weight can make the tractor hard to steer and can reduce its agility, which is a crucial factor when operating a backhoe.
- Rougher ride: Filled tires lose the air cushion that normally absorbs bumps, resulting in a harsher ride over uneven terrain, especially when traveling on roads.
- Difficult maintenance: A fluid-filled tire is much heavier, making it more difficult to remove for a puncture or other tire issues. The fluid itself can also create a messy spill if the tire is punctured.
- Potential for overworking the tractor: The added weight can cause the tractor to be overworked, which can lead to accelerated wear and tear on its components.

I also don't agree with that fake intelligence rambling ... My Massey Ferguson GC 1725 MB TLB came with no such "advise"!
I bought my L2501 new from the dealer with BH77 and he loaded the tires.
I've read the notice after seeing it here and OTT, but can't for the life of me understand or bothered to have that discussion with the dealer. My BH77 isn't on all the time and I want the traction of filled tires both ways.
I wonder if it is just a pad up the sale to load all rear tires as I think it cost me about $500 more.
Or it could be that a lot of sales people aren't really that well versed with the equipment they sell.

And I liquid filled my rears ... And added 3" spacers ... Then I added ... factory steel wheel weights ... !
I think the weight of my axle, spacers, wheels/tires, liquid fill, and wheel weights are much less weight than what the weight the axles bear when the tires are on the ground, and the full weight of the tractor and operator are bouncing over uneven ground ...
Here are a few possibilities ...
1. Maybe Massey Ferguson builds a stronger tractor ...
2. Maybe I just haven't jerked it around hard enough in the 735 hours I've had it since new?
3. Maybe I just need to put more hours on it?
4. Maybe it's a very rare occurrence due to a bad/faulty axle breaking, and the other hundreds of thousands of S/CUT Kubota TLB'S haven't broken an axle even with liquid filled tires? (Never heard of a stabilizer breaking/bending)
5. Maybe they are just covering there backside worried the extra weight will be too much if the operator is already over 500 Lbs ...
6. Maybe it a mistake in the manual (I've found things that were wrong in manuals!)
