Liquid filled LT1046 rear tires?

Also agree that an LT isn't designed for that.

However, describe what traction issues you are having going down loaded on the steep slope. Next question is are you using the stock turf tyres?
If you are using turf tyres, generally they are fine for dry flat lawns, anything else they are simply horrible no matter the weight on them. You would be much better off with ag tyres or even atv tyres on all four wheels.

I also agree that a loader of any description doesn't belong on an LT.

Having stated the obvious, yes, loaded tires will help.

Where I'll disagree with Flaken is in the choice of tires. A set of 2-link chains on turfs will add weight and allow more fluid to be carried than with other tread types. Heavily lugged tires have less interior volume for the same outside diameter as turfs with their thin tread. The chains sit on top of the tread rather than settle between the lugs on other tires, thus giving as much, or more, traction on dry, firm ground that the larger lugs can't penetrate.

If the ground is soft and/or wet, I agree with Flaken. But with that much load on the small front tires, you will get stuck in soft/wet ground, so it's kind of academic.

Lugged front tires on a loader equipped tractor makes for hard steering. A smoother tire makes for easier steering. There is more than enough weight with just the loader for steering traction.

Thanks to all for the replies. Fortunately, the project with the bullrock is pretty much a one-shot deal — I’m using the bullrock to fill gabions that will create an 18-30” high, 24” wide retaining wall, which I will then line with landscape fabric and backfill. End result will be a 6’ wide path with a much more gradual slope than currently exists, so that I can get the tractor and other landscaping equipment up and down the slope easier. (Essentially, I use the LT + Johnny Bucket instead of a wheelbarrow or garden cart — once this project is done, mostly it just moves a few yards of mulch periodically.)

The existing slope in the “bad” area (only aboùt 30’ long) is such that the unloaded tractor can just make it up (with the rear wheels slipping a bit). The problem I’m having is that when coming down loaded, even proceeding dead slow or with the brakes locking the rear wheels, you still are slowly skidding down the slope (which is primarily caliche — very dry). I can steer, but not stop, until reaching a “run out” at the bottom of the slope.) Adding extra weight to the back helped considerably, but for the reasons you indicate I’m hesitant to add a bunch more.

So, recognizing the issues and conditions, should I be looking at ATV tires (if so, any recommendations)? Chains on the existing turf tires?

Oh, don't disagree that different tyres will handle differently than the turf tyres. A part of my yard remains soggy almost year round and the turfs just slide about almost as if they are unwilling to turn. Completely dry grass to mow is almost a rarity this year.

Have a new project lawn tractor with turf tyres. Tyres are the first thing to go. Contemplating these:

Both front and rear are ATV style and definitely NOT turf tyres. I'll see how they do.

Update: success!

Flaken nailed it: the key is to ditch the turf tires and use higher traction ones. I got two of these:

Wound up just filling them with water and dismounting my mower deck (results in about the same total weight but more maneuverable). Now, I can stop pretty much wherever I need to on the slope when loaded, and can get back up the slope no problem with an empty bucket.

Thank you for the mention!
The Cub Cadet GT2544 I had used the stock turf tyres and I just couldn't get any traction around my yard. Then I got a pair of Chinese made chevron lug tyres very similar to the ones you got, though much less expensive. After mounting those, getting stuck somewhere became a real challenge, though I did try. Once I was over the axles deep in mud and just the patient forward and reverse repeated got me out. Never would have done that with turf tyres.
