SF, I have a tc35d with the 16la and R4s for 25hrs now and haven't noticed any bad stability. The front/back is good, I've had the bucket full and very high and it's a little rocky, but that's the same for every tractor/loader/etc. As far as left/right the wheels seem to be very wide enough for comfort. Like any tractor, big or small, there's a limit to what you can do. I had a b2400 for several years and 210hrs and there were a few time I was up on one tire with the loader full and high. So maybe find a hill near your dealers and put the models to the test...with seatbelt on!! Of course!!/w3tcompact/icons/wink.gif
