I am considering the purchase of a zero turn mower for my one acre lawn. I spend a lot of wasted time rounding corners and trying to mow around trees, with my lawn tractor. I am only considering a 42" residential mower with a cost of less than $3000. There are many available choices (Cub Cadet, Troy-Bilt, Toro, Exmark, Snapper and others). I know a commercial grade mower would be of better quality, but I have to draw the line somewhere. Of the residential, 42", zero turn mowers, which would you recommend. Thank you for your time and experience.
