What are the dimensions on your raised beds?
The two in the foreground of the hoophouse are 10ft x 10ft x 12inches deep, and the one at the end of the hoophouse is 12ft x 12ft x 12inches deep. If I were to do it again, I would make them 12ft x 2ft x 12inches for easier access down the center.
When I built mine I made them 4'x4'x1' deep. The idea at the time was
1- simplicity. A sheet of 3/4" plywood split down the middle, then ripped into 1' strips would make frames for 2 boxes.
2- EZ maintenance. By being 4' square you can reach the center from any side with ease for planting & weeding.
If I ever build another set of raised beds I would keep them 1' deep, but make them long. Maybe 20 - 24 feet long. As for width, I would make it the width of my full size rototiller + 1" clearance on each side. Then I could blast through it in the spring in one pass and be ready to plant.
