The lift specs mentioned are at full height. I know Chris has lifted much heavier weights with his loader on the 2520, but I wonder if that was at full height. Full height is pretty high, much higher than one would seem to need to service a jet ski. One might be looking at 2 to 2.5 times the lift ability at 4 ft. for example v. full height. That would put the 200cx on the 2520 at a lift capacity of around 1500-1800#, if not slightly more, at a lesser height. This is one aspect the spec sheets here do not address. I think both parties can be correct. Although I have not owned one personally, I think the rate-limiting step of the 2520 with the 200cx is the ability to safely ballast the weight it can lift. Even with my 3720 I have been able to lift the rear of the tractor free of the ground when the bucket has been wedged under a large, embedded rock, so I know it has far more capacity than its rated 1598# at just over a foot less lift height.
