I have
ballast (Rimguard) in my rear tires, and I always have something on the 3 pt hitch as well. I do various odd loader work and randomly have to lift objects from the "not very heavy" class, all the way up to the "nope, can't lift this one" class. Currently the heaviest 3 pt attachment I have is my 6' snow blower, which weighs almost 800 lbs. If I had a "max" lift to do, I would want either that one, or my 6' mower on back. Not that the mower is much heavier, but with the center of the weight so far back on the mower, it acts on the tractor frame like a much heavier weight would up close. There's just not always room to do the lift and carry with that much length sticking off of the back of the tractor.
I have never once regretted having my rear tires filled, but I do have to be cognizant on where I drive it and what is on or under the surface. Case in point, I cannot drive over my septic field, it would crush the field pipes just under ground.
I do know how much mine weighs. I weighed it on a local CAT scale soon after purchase. With the FEL and bucket on front, and my 6' box blade on back, with I believe a full tank of fuel, it weighs 7100 lbs.
I have really enjoyed the simplicity of not having any "Tier-Any" emissions garbage on my tractor. Once I freed myself of the emissions problems, it's never needed to go back to a shop or dealer for anything. In March, it will be 7 years old, it's paid for, and it just keeps chugging along. I never once considered "resale" value when purchasing my tractor. Like someone else said, "It's a tool, not an investment."
I can see myself adding a sub compact to the "fleet" at some point. I wouldn't replace the Branson with it, but sooner or later my riding mower is going to need replacement. I can see the value of a sub compact with FEL and belly mower to take the place of the riding mower. Mrs Slim is intimidated by the size of the Branson (still) and not at all comfortable running it. I think a smaller SCUT that she can run and use for gardening, pulling a small trailer, and having a lighter FEL for potting soil or mulch, etc would be handy to have around.
