I've been mowing a half-acre of grass (my own lawn) for several years now. First, I used a high quality 21-inch mower (too much work/time). More recently, I used a Toro Timemaster (took it back because it hydrolocked and started leaking gas 60 days after purchase). Now, I'm wondering what my best option is for about $1,500 or less (I don't want a riding mower). I could get a nice used Toro 32 or 36 belt drive, but would that be too much for me? I'm not a big guy (5' 10" 150lbs.), I'm not mechanically inclined, and I don't have a pickup truck to transport the mower when it needs service. If it matters, my lawn is thick St. Augustine that I mow at 4". The lot is gently sloped, but not "hilly." Please give me your recommendations. Thanks.
