I had a tractor when I had a 22 acre farm, and loved it [especially bush-hogging]. Wish I had one now, but with an acre of land . . . my pride and joy now is a BCS walk-behind tractor with a rear tine tiller that does a very impressive job

It's just me, so once everything starts coming in, I have to let a lot of the weeding go so I can can and freeze, etc, so I guess my late garden is more in line with your wife's garden.
My aggravation with the planter is it will go about 4 rotations without planting a seed, then drop 4 or 5 seed for awhile - and I end up having to do too much bending to straighten it out. I just plant my little post at each end of the garden, turn my hoe upside down and make a run post to post - go back and drop the seed, then cover - it takes about 5 minutes per row. Then the little post keep my garden hose from running over plants when I water.
Looks like you plant indeterminate tomatoes. I do both, mostly heirloom Cherokee Purple, Brandywine. I always planted buckwheat for the bees too, and interestingly enough, the deer preferred the buckwheat to my garden vegetables.
