We don’t have access to a variety of digging machines here (only to a stadard tractor with a front loader + diggins spoon) so these pictures caught my attention – digging swales and berms using a tractor with a combination of plows:
… and water it holds:
Three terms I found mentioned in the forum thread where I found this
- The moldboard plow sounds like something that is typically used by farmers in our area to break-up soil.
- I have not been able to find much formal informatn about a “drag blade plow” but as I understand it is used to move the soil after it is broken up by the moldboard plow.
So it is about repeting numerous cycles of loosening and shifting … how many cycles depends on the depth and width of the swale and the number of blades on the plow.
