Hey everybody, Let me get some opinions from you all. My Dad's birthday is coming up and I want to get him a new garden tiller. I don't know a lot about brands and horsepower. His garden is about 1/2 acre,by the way. I looked at the Lowe's and Sear's websites. I'd like to stay in a $500-$600 range atleast. It doesn't need to be fancy and have any extras. I'm wanting to know what brands are reliable. What horsepower would be about right for a 1/2 acre garden? Just the general opinion,please Thanks.
