I use a Krone AM 212 (without conditioner) which i bought 2 years ago for 600 Euro. it folds hydraulically and the 5245 doesnt even notice its there.

What is a 5245?

Now when i hook it to the 2011 to put it in the back of the low barn (1400 kg, 25 hp) you sure notice its there... But 25 hp would come a bit short to drive a 2.10 meter mower anyways.
I'll try the 3011 this spring, it has abit more weight but more important, more power. 39 hp should be able to work with it at reasonable speeds.

What is a 2011 or a 3011?
Mower caddies are unknown in Europe. some manufacturers sell pull type mowers but a caddy to pull a 3pt hitch mower would make most Europeans laugh...
The trend is towards 3 meter front, 3 meter rear 3pt hitch mowers, or 3 meter front, 2x 3 meter batwings rear.
Most popular farm mower is a 2.80 to 3.20 meter disk mower with V-tine conditioner. Anything strong enough to drive it, has enough weight to carry it.

Interesting - i don't know anybody aorund here that uses front mowers or the batwing rear.
Also - you are not quite right on the enough power vs. weight.
I have a John Deere 4720 that will power my HX-15 batwing, but I am pretty sure the batwing would be doing the driving except on very level ground.
In regards to the 2.8 meter mower - not sure my 4720 would like that thing attached to the rear. I am pretty sure 58hp will drive it. With a mower caddy my 4720 should handle it OK and it makes hook up and storage much easier.

I will give a report on it when I have it up and running. I will try it on my 4720 also.
