Mine is red -- the Case DX29 version of your machine. I have the CNH loader, which puts the bucket further out in front of the front wheels and alters the leverage a fair amount compared to a conventional loader.
I have about 130 lb of home-made weights on each wheel, about 900 lb. of concrete hanging on the 3 point. I have an Add-a-Grapple on the bucket which puts about another 140 lb or so out front. I also have a home-made toothbar that weighs about 75 lb on the bucket. I'm running Ag tires. I move dirt, rocky dirt, mulch, oak/hickory/locust firewood, same stuff as logs to become firewood, and pretty good sized rocks around my tilted ground. Even with all the weight, carrying a heavy piece of field stone or a 12 or 14' hickory or locust log across the hill can get interesting, the logs especially since any irregularity in the ground is multiplied out at the ends of the log. My ground is pretty much all 4/12 pitch -- think pole barn roof with dirt, trees, rocks, brush and grass on it. With heavy loads when I must move cross slope the load is low and on the high side of the bucket.
I have had the tractor on 3 wheels when pointed uphill once in a while by lifting a rear, and on the front two when trying to lift a too big field stone when I didn't have the wheel weights on. With them, it won't pick up the stone or the rears, so I figure I have about the correct amount of weight now.
I do not have the tires loaded, and run about 9 psi in the rear with 35 in the fronts. I opted for the big tires when I ordered them.
I get bounce from the seat mostly, very little from the tires, when carrying something heavy. Still the seat bounce is enough to get my attention in a hurry since my previous tractor did not have a suspension seat and any bounce I felt was the whole tractor moving.
