I have almost 2 acres, and bought a new JD LT166 the same time I moved
here.

I've regretted it ever since. 15" turning radius sounded small at the
time, but I spend hours backing up or doing loops.

I'm trading it in on a Dixon 4515 zero-turn.

I know someone who bought an older Dixon for $1500, and she mows lawns
for money. She runs that thing at least 25 hours/week, and has not
had a problem with it in the two years she's had it.

So anyway, my point is, for the size lawn you have, maybe investigate
used zero-turn mowers. I chickened out last year, because I was
looking at expensive mowers (Grasshopper, Lazer Z, Walker), but the
Dixon is priced more realistically for me ($4120 - trade-in).
