My Troy-bilt tiller is 12 years old and I had to replace the carb this year. It still runs jusr like a brand new one and I till about 1/2 acre every year, the use it 3 or 4 time to control weeds. Wouldn't do without it. My wife cans or freezes just about all the extra that comes out of the garden. We use soaker hose on everything and will put them on a timer if we are going to be away for a few days. In West Texas, the frequent watering is necessary.
