Plowing sod is like pushing a rope up a hill. It doesn't usually go where you want it to. All in all, your plowing doesn't look too bad. Not only have I seen worse, I've DONE worse.
When you plow sod, it needs to be worked as soon as possible. (i.e. disc, tiller, or whatever secondary tillage tool you'll use) Let it lay in the sun a few days and you've got your work cut out for yourself. A disc OR a tiller will get the job done. A tiller will do a BETTER job most likely.
I never was the brightest crayon in the box of 64 colors. Never did listen to my parents. I HAD to marry young, start a family too soon, and struggle to make ends meet. In those early years, our garden was all that stood between me and hunger at times. It was essential to make it work. The #1 trick I learned? READ THE LITTLE PLASTIC TAGS THAT COME IN THE PLANTS and/or THE PACKAGE THE SEED COMES IN. Lots of valuable info there for the taking.
#2 trick? I plant TWO gardens. No, not 2 of everything, but 2 seperate plots. That allows me to rotate things year to year. i.e. Never plant your tomatoes in the same spot 2 years in a row. (disease) Broccoli and cauliflour need to be as far apart as possible to prevent cross-pollination.
Don't try to over-think things. Mother Nature will do her best when you don't try to interfere too much.
Don't try to rush the seasons. Planting too early won't make veggies earlier in most cases.
Good drainage is VERY important. You can always ADD water if needed, but when your garden turns in to the Everglades, you're outta luck.
Two old sayings from baseball legend apply directly to gardening.... You win some, You loose some, and some get rained out..... and..... There's always next year. Not every crop will be a bumper crop. Take what you get and remember what you did right as well as what you do WRONG and carry that knowledge to the next season.
I'll load up a tractor and plow and drive halfway across the state for an opportunity to plow ground. That said, The ONLY time I plow a garden of mine is the first year to flip the sod. After that, two words, MINIMUM TILLAGE. I've got 3 (running) tractors, 3 plows, a 3-point tiller, 2 "walk-behind" tillers, 2 disc's, and a field cultivator. All I use in the garden is the smallest of the 2 walk-behind tillers. Soil generally does its best when you don't work it to death.
I'm at my happiest when I'm out crawling around in the dirt planting something. Don't turn it into a job. ENJOY it.
