Erm, think you might be reading someone else's experience, not saying I don't like flails for the job they can do or the relatively low damages from it eating things.
Low hp tractors such as the op are definitely topper type, without it becoming tediously slow.
I will be going back to a topper with a smaller fergy tractor, my 80+ hp with a 2m flail on ground that makes a goat clench when you're 14ft off the floor doing overgrown scrub is boring.
Trying to get back to managed pastures, flying around after a bit of sheep grazing.
