I currently have a 1/2 acre yard; been doing it with 21" that takes too long. I'm planning on getting a quick product. We are also planning on moving to another house in about 1 year with a 1 acre yard. The question is, should I get a 36" or 44" Quick? Is 44" going to be too small for the 1acre? Or do I get the 36" now, and buy a rider when we move and use the 36" for trimming.
