I'll start checking that site out, thanks for the lead.
I'm running a JD 5300 and want something that can take what the tractor dishes out. It seems the tractor is a bit too much for the Bush Hog RDTH 84 finish mower to hold up to even as my finishing mower for here at the house because it will sometimes be high ankle deep before cutting. Hoping a flail will fill my needs for finish work at home, cutting down deer food plots before discing for planting each year as well as clearing out roads around the camp which will include patches of switch cane and thick stands of johnson grass. From the talk about flails it sounds like they would do a better job of dealing with the residue vs the clumps the Bush Hog 287 brush cutter does. Back when my Woods RM990 was functional I used it on the roads and plot because the swing blades dealt well with the ant hills and clumps of dirt as well as downed limbs while chopping the residue up a bit more and not leaving as many clumps of grass piled up in the plots but it was slo-o-o-w going. Hoping the right flail might fall somewhere between the two since I can't get out to the place to mow/brush cut often enough to eliminate the quantity of fresh residue so need alternatives.
If I understand discussion correctly using a flail under my circumstances will be a slower process than the rotary cutter because of the amount of residue chopping a flail will when compared to the common brush cutter which whacks the grass down and leaves it in clumped windrows. For all I know at this point I may be asking too much from a flail mower.
