I would appreciate your advice especially considering I've never used a flail mower. In the near future I plan on purchasing a slightly more powerful tractor with some upgraded features, likely Kubota B2601 or B2650, both about 26hp (19.5hp pto). The plan all along was to include a 60" mmm but I'm wondering if a 60" flail could do everything I currently do with my 54"mmm, and maybe more?
Here's what I now cut; the yard area around the house at 3.5", another area a bit rougher at 4", and a small pasture 3-4 times a year with the deck raised all the way so around 6" which is slow going and I have to go over some parts twice to get it down. I like the yard to look pretty decent but I'm by no means obsessed with having a pristine lawn. So all three areas are just grass, weeds, some light brush, no heavy brush.
The "maybe more" would be to use it on our ATV trails maybe twice a year to cut weeds and the occasional small saplings nothing more than 1/2". For this it will need to be run while raised up, again maybe 6", due to the uneven terrain, rock outcroppings, small stumps, etc. This would be be something new because currently I use a heavy duty weed eater on the trails and along the edge of our dirt/gravel road.
After reading through this thread it seems a flail such as a Peruzzi Fox S-1600
Iowa Farm Equipment -- Peruzzo Fox S Side Shift Series Flail Mowers could accomplish all my requirements and it's not all that much more than buying the 60" mmm. Any thoughts regarding a Fox S-1600 (or any other flail) for my application?
