I think I want a 12’ batwing chopper to maintain a hunting lease. Mowing around 60 acres annually of 4’ tall grass/weeds and brush up to 2” thick. The field isn’t all that thick, but some is. The property has some rolling hills but nothing steep. My 6060 is open station with a loader. Will it handle the 12’ or should I go with a 10’?
Your 53 PTO HP
L6060 should handle a 12' BW in many conditions so long as you do not expect to set speed records. That said, 2" is getting up there unless the brush is rather soft.
Sounds like you plan to mow only once each year. If so, August, or even winter is the time when it will cut most easily. Keep in mind that heavy grass requires much more HP than does tall brush and weeds.
Before buying your mower, carefully research the required distance between the drawbar and PTO shaft. Some cutters and, I believe all with so-called self-leveling hitches, require more distance between the drawbar and PTO shaft than your
L6060 has. Yes, Kubota offers a dropped drawbar to address this condition, but your hitch will be very close to the ground when using one.
FWIW, I used a heavy Woods BB720X 6' cutter with my
L6060 ROPS, since sold, and it was all it wanted in some conditions. Yes, I do cut close but also keep blades sharp.
