i have a 36" w/b, a 48" w/b and just bought a new 60"lazer z as. would it be necessary to keep the 36". it seems two me that the 48 and 60 would do good enough and the two will still fit on the trailer. there are two of us, so i don't know if it would be worth the trouble of keeping it, but it would be good for a backup mower, i guess. any idea to keep it?
