Hey Everyone, my husband and I are too old to deal with a walk-behind mower and our son can no longer cut our grass. So, we are thinking of getting a ride-on mower. We have about 1/4 acre to mow with some tight spaces, bird bath, and trees. Without considering cost, since reliability, easy of use and maintenance--not to mention maneuverability--are important considerations for us, would you be able to recommend one, and why?
