I cut my own 1 acre lawn with a 30 year old Deere 210 on Sunday and all went well. I cut my mom's 1 1/2 acre lawn last night with a 27 year old Deere 316 and all went well. In fact it was better than that, it was excellent.
Nothing is as good as seat time, after a stress filled day at work combined with a long white knucked commute. Somehow 3 to 4 mph on the grass is very soothing........
