I whined and got a Kubota tractor with cutter, loader, and tiller 12 years ago. Last year I added a rear digger. It turned out to be almost everything needed except for small areas. That may not be available any more, but buying a used one and spending $500 for any given part not included might be a way in for rowing and going like a 20-year old when you're 70 and your body doesn't do what you tell it to do any more. hehehe... A less expensive way to tilling might be to get a tiller that has a feature of pushing itself. It would cost 1/20 less than the Kubota, except you might get your boots dirty, and you could pay $25. to a neighborhood kid who would be glad to trade his muscle for being a helping hand once in a while. You could also contact the local football coach to keep a player or two in shape off-season to work summers to keep your place spiffy. Helps him afford going to a movie now and then and you get some work done instead of feeling bad about feeling bad. The only other thing I can think of to help you get over hurting is a product on tv these days to help you get over hurting that old age brings just when you want to do some heavy lifting. It's something about factoring relief for pains that accompany aging. But before you go on a sales organization's self-review, you might go to a consumer review site first before you decide it is or is not for you:

It pays to be careful most of the time. Other times, you might be surprised how something works for several years. Some of us like to see our own elbows doing our work for us, and it's possibly cheaper if we learn the ins and outs of nutrition. Doing nothing, however, is the worst of all options, imho. For example, I failed to ask if I could run a marathon after knee replacement surgery. My physician said, "no" when I asked him 6 weeks post surgery and full-time rehab with certified rehabilitation therapists. lol Now my leg-and-hip sockets hurt. I'm going to try out the relief factor place, because I'm tired of thinking about gardening when the pain goes away. And it doesn't go away without a little cooperation on the sufferer's part. Just my two cents worth of useless advice.
