Hard to say. The hydro will pressure relief if it can't spin the output shaft. The 2 and 3K series hold so much oil, it would take a lot to severely overheat the oil. As long as you don't get crazy with tongue weight and expect to stop in a downhill situation, it's a try and see thing. I know I dragged a 2'x5' x ~1' thick slab of concrete with a nylon sling a few hundred feet across the lawn w/out the slightest lack of pulling power.

Thanks for the info
Is it imperative to run the engine at WOT (like when mowing) just to move stuff around or doesn't the trans really care about RPM to operate?
...I wish I had my old gear box back sometimes.

Just to putt around the yard it's not much of an issue, but the hydro will be awfully whiny. The engine and trans is designed to be most efficient at max governed RPM.

I thinks it's 1500 lbs. Read it somewhere on the Cub site.
From the horse's mouth (CC faqs):
"This is a more complicated issue than it might appear, because "towing capacity" is more of a sales specification than a technical specification. If you picture yourself pushing a wheelbarrow full of dirt, weighing about 300 pounds, you would say that your pushing capacity was 300 lbs, but I doubt you would be able to push 300 pounds if it were on a flat sled with no wheels on rough ground. That is a simple analogy explaining why we don't use towing capacity as a technical specification.
Everyone likes to relate axle torque to draw bar force, but draw bar force cannot so easily be related to "towing capacity" due to all the variables involved. There is also a difference between a maximum axle torque (or draw bar force) short duration spike compared with what can be sustained over a long distance such as in towing. On most surfaces, unless you significantly weight down the tractor, you will generate tire slippage before you reach the transmission's ability to create maximum axle torque.
The 1000 Series & LT1500 Series can handle a typical lawn cart with a 750 lb. capacity and a lawn roller of 650 lbs.
The iSeries can handle a lawn cart with a 1500 lb. capacity and a lawn roller of 950 lbs.
The GT1500 Series can handle a lawn cart with a 1500 lb. capacity and a lawn roller of 950 lbs.
The 2500 and 3000 Series can handle a lawn cart with a 1500 lb. capacity and a lawn roller of 950 lbs.
CAUTION: You should also be cautious of "braking ability". These tractors have a single disc brake designed to stop the weight of the tractor on slight grades. When you are towing downhill your braking distance will significantly increase. As a general rule of thumb, using a single-axle wheeled trailer you should be able to pull half the weight of the tractor safely over level ground and slopes less than 5 degrees."

On my MF, if I raise it just above half throttle then the transmission doesn't whine noticeably just for running around the yard. Even when I'm aerating, I don't run at full throttle, more like 2/3-3/4 throttle. It cuts down on the noise even running that little bit below WOT. That is the downside to hst though--they aren't really good at putting around just above idle like a gear drive is.
