Hey all. I've been renting a large rear-time tiller for the past few years to till my garden. My husband just told me I could buy a tiller. The issue is that I'm a small woman with little upper body strength. I want to get a tiller that I can use instead of waiting on my husband. Also we have clay/sandy soil with invasive grasses that have to be broken up every year. Any suggestions on which tiller to buy?
