In spring I hope to take up a pretty large commercial account and I would need to get another mower to handle the extra amount of mowing. I have a 52 inch z so I was considering a 60 inch w.b.Gear drive with a sulkey with a fixed deck . Does anyone know who makes a good one ? so far I have looked at toro exmark and j.d. and no one makes a 60 inch cut. Thanks in advance!
