My ballast barrel is about 750 lbs or so and I carry close to 100 more in the form of chains, crowbars, shovel etc. BUT still I wish it was more. I have loaded tires, and my similar sized tractor weighs over 1000 lbs more than its comparable sized Kubota standard L series. But with all of that, I would be very carefull with the 1200 lb bales. Low and slow is the way. My CUT is a heavy stout little dude, but an M series Kubota or something else similar sized would be a better bet for moving those things day in and day out.
