It appears that, if you’re rototilling a garden that’s gone to grass and blackberries for the past six years, watering prior to tilling makes it easier to remove the vegetation. It looks like a softer, wetter soil allows the tines to pull plants bodily out of the soil instead of chopping them up but leaving the rhizomes. Of course, when you’re tilling mud the tractor gets stuck more easily. If, like me, you’re running a walking tractor it’s not a problem but just takes some muscle to get moving again.

Of course, I still hate rototilling and want to find an affordable, labor-efficient, and less intrusive method of soil preparation.
