Looking around for affordable flails rates to cut 3” plus material, and I found this model by Lipa:
LIPA TLS 180 Tractor Mounted Flail Mower (72″ Cut, 3Pt – With Side Shift) For 50-60 hp Tractors
The only other in stock brand I can find is the Betstco:
63" Super Heavy Duty Trail Cutter/Flail Mower, FH-D160 | Betstco Sales, Parts, and Service:
They have a 63” and a 72”. The Lipa is 72”. With any of these models, I’d only be able to run them on my 60hp Kubota. I spoke to a woman at Betsco on Friday, she was very nice and helpful, but I did not get he impression she knew much about the D series they sell. I like the idea of saving money, and I like the 5” rating, but something tells me the Lipa will be a much better machine than the Chinese Betstco.
