Hello, I really dislike the "Smart Drive" on my HRR mower. The difficulty with the rear wheels locking when pulling backwards is well documented and I'm aware of the various fixes. I'm considering a new mower and would like to know from those that have the HRX217 with the hydro drive "Cruise Control" if it pulls backward easily to maneuver or does it sometimes lock the rear wheels? I've searched the forum but I've not found any post concerning locking rear wheels with the hydro drive so I'm thinking that it doesn't have that problem.
