How Much Flail Mower for 38-Horse Kubota?

I see that most disc mowers for mowing hay and grass fields that are 3 point mounted can be negatively tilted to 30 degrees or so below grade level. ASC sells a few in various widths.

My previous machine was a L3200 & it was way to light to run anything seriously offset.

The Peruzzo above is fully offset in the picture. It will slide left around 2-3'. It twists things as much as I'm comfortable if offset fully & I lift it. I usually center it before lifting it off the ground.

I often run a 71" cut ditch bank flail,( weighs 1450#). As others have stated, there will be "pucker"
moments when flail is fully extended with the head down as in position to mow around a tank.
Go slow and pay attention. If the flail roller hits a bump and comes back down to position you
will definitely feel it in the cab, as the flail head will kind of bounce. I could have gone to a
bigger flail but I'm glad I did not. Your uses may vary from mine, but you have received some
good advice from from several folks on this thread.
Btw, just so you realize the power of a flail, not just the weight.....
I'm attaching a pic of a shovel one of my grandkids
left out in the middle of a field I was mowing with the flail. Cutting height was set at 6", a fairly
new shovel......Flail vs Shovel. One quick pass at 3.2 mph. No damage to flail or hammers.....
shovel didn't fair so well.
Good luck with your decision.

The contractor that mows the roadside ditch banks here has a medium sized JD with an arm mounted flail on it and I've seen tires, hubcaps, old appliance parts and who know what else and it just keeps mowing. He' has cast centers plus a side mount (left side) counterweight as well. Said to my wife that maybe I should bid on the contract as I know what he gets paid, 25 grand a summer for 2 mows, but the wife said no. He only has to mow 5 feet from the road edge. I have plenty enough to do as it is with managing the shop, fiddling with hay and keeping the farm up. I need to slow down a bit at 74 and I really don't need to buy another piece of equipment either. Not sure what he has but I believe it's a Kuhn.
