I have bx2660 with fel and 5' finish mower. Getting old and have a terrible back so thinking of trading up to b2601 with fel and 60" mmm for a smoother ride, will I achieve that goal with the trade?
Depends on how big a fella you are.You might look at the B2650 also. It has a suspension seat that might be more comfortable. It also has a longer wheelbase which will help with the ride.
At 180# I'm ok, no bottoming other than on the deepest sharp dip, with preload at max. I guess it's a combination of the seat, longer wheelbase, wider track, and maybe tires, but the B2650 definitely rides smoother than my previous B7500. And way smoother than the wife's JD X310 lawn tractor.Depends on how big a fella you are.
I weigh 210 and with the preload on the seat springs set at max it still bottoms pretty hard on any significant bumps.
