After reading all that you have done, I need to go lay down and rest.LOL
You have a lot going on.
The old Troy did the 150 X 50 garden (minus maybe 1/8 of it that's planted to perennials, wheat, and fall planted onions & garlic) in about an hour at low speed & full depth. Moisture just right, and several years of organic matter added...and rocks removed.
The peas went in with the old Earth Way seeder in less than 30 minutes. Put the right seed plate on it, set the depth, fill it up, and push it down the new row.
The onions were about 4 hours of work over 3 days, and I got to lounge while replanting.
Oh, my! Mrs. A.R. just heard something strange, so I looked outside: it's raining! Perfect for the peas & the onions. And if it continues, I won't have to do anything tomorrow!
