Flail mower for CT225

[gregfender]

I've got a Bobcat CT225 and I'm looking to drag a flail mower behind it. Primary use will be to cut pasture grass (less than a foot...usually <6") and the right of way on my road. Can I get away with a 72" or am I getting a little ambitious?

28HP, 20@PTO

Any advice is welcomed.

Thanks!
