Hi J J,
Do you have the PT flail mower or did you adapt something else? How well does it work for you?
I have an 1845 in Colorado with all the mountain, tree and snow tools, but are relocating to where I have serious grass to deal with instead. Love the PT, but not sure if I want to go to all the effort to sell the bits & pieces I won't need, move the rest and buy a flail for it......but it is a possibility.
Notice you also have a full-size Kubota.......one of my other options for grass is a used ex-municipal 2009 Kubota 4wd F-2880 with 60" deck......may be good enough as is to do all my 4 acres of grass or can be fitted with a flail for the real rough stuff.....should handle the slopes here also.
If I got the F2880, would be looking to buy or make a front carry-all to replace the mower deck just to move stuff around.....you seen something along those lines??
Cheers, Rip
