Toro is supposed to come up with a commercial version of the 30" time master. I hope they put some casters on the front wheels.
We have a whole lot of 1/7 ac lots with 2.5K SF of turf and a 36" gate. While I do not think it is real hard to learn pistol grips, I can not count on guys to use them. Easier controls are required.
MFG's seem focused on Z turns and 48+ WB.
