I keep forgetting that things like rototillers exist. Woulda saved me a lot of trouble at the house! Not that I had more than a few feet (literally) to rototill.
Do they rent 'em by the weekend or something? Are they pretty easy to use?
Sure - you could rent it for a day or a weekend. They come small or big... we used to have a rather big one growing up, cuz mom had a big garden, it was a little scary to operate but it gets the job done fast :~D
There are some jobs you can bust your butt all weekend and not get very far, or rent a machine and do the same thing in an hour.... rototilling is one of them. :~D
