My garden is 1350sqft and I use my garden tractor to plow it and I use a Troy Bilt tiller I bought in 2005 for $100.00 to till the garden.
I plant double rows of green & yellow beans about a foot apart. I use my Mantis tiller to till in between and on the outer edges. In about 2 weeks once they they're up I replant another crop. The Mantis tiller is 25 years old. I also use it around the tomato and pepper plants. When they get big I use a garden hoe that has two small culivator teeth. I mulch the tomato plants with grass clippings and I use wire cages made from heavy reinforcement wire about 36 years ago. I mow off the bean vines and plow them under. I don't do that to the tomato vines. They're picked up and composted at the local landfill. Hal
