I haven't used the flail mower on my Grillos, a G-85d and a G-107d. I have used the bush hog and finish mower for those two units though. Since 2015 they have been reliable and versatile machines on my little farm! List of my attachments, driven wheeled trailer, CAEB dump cart, CAEB baler, Molon Rake, BCS 60" sickle bar mower, 26" Del Morino brush hog, two Zannon finish mowers, Berta Rotary plow, Rinaldi power harrow, tillers,chipper/shredder, and trencher. So, if you are reading this it gives a good indication of the task these little tractors can perform!
