I use a very heavy 72" flail mower (Flaco over 1000lbs) on a Kubota 3940 HST about 32 HP at the PTO. When the weeds are very tall and green, it slows down, so must I slow down the speed. The HST makes this so easy to instantly slow down. My only concern about using larger flail mowers especially with the loader off (the way I almost always do it) is the light weight on the front end. Adding weight is great but I can't do that with the given configuration and loader attached. I did have a 6" X 6" X2 ' tube I filled with concrete and welded under the weight rack, adds about 100lbs out front. Another thing is I mow in 2WD 99% of the time. If I strike an object like a old stump that went between the front wheels and I could not feel, I am more likely to spin the tires. That is what I want. The wider the cut the easier it is to bend the flail tube as well. Even the slightest bend will vibrate the heck out of the mower and tractor. Unless you know what you are mowing, it is best to go slow anyway for that reason alone.Looking a a Titian( TN made) flail mower, do you think I should get the 64 or 72 inch flail?
dealer thinks I should get the smaller cut, thinks flails eat up a lot of HP.
