I just bought a 1/2 acre property and the lawn is a challenge. It's about 1/4 acre of grass, but the lot is on a steep hill and the terrain makes for mowing on about three different elevations with lots of turns, trees, side slopes, etc. I used my self-propelled push mower, but it took 40 mins and was A LOT of work. I don't think my lawn tractor would be of much use either. I'm trying to decide between a compact zero turn (maybe 30" deck?) or a real walk-behind like a commercial unit (scag, etc), but obviously cheaper. I'd like to stay around $2k and be done with my grass in under 20 mins. Ideas?
