As I said in another thread, I am going to start using minimum tillage methods in my garden. A disc was not on my list of tools to use in preparation for planting. I did want one though for two purposes. One was to cut sod when preparing a new garden spot, but the main use was to disc in cornstalks after harvesting sweet corn.
I hope I don't offend anyone by saying this, but the videos I have seen of people dragging a little disc with an atv or garden tractor looks to me like they're just scratching the top instead of actually working the ground. I had hoped that by building this disc much heavier than many others it would actually do some work.
The short version is, with a 17* cut, weighing over 300lbs, and using down pressure on the 3 pt hitch, it still won't cut hot butter.
I threw some cornstalks crossways in my garden that I had tilled a week before. The disc would only go 2 or 3 inches into the dirt, and when it came to a cornstalk, instead of cutting, it just rolled over them. When I tried it in sod, It left it undisturbed except for some slice marks.
I guess I'm just biased after using big farm equipment, but as far as I'm concerned, I have no use for this disc.
Since I have enough parts to make 2 or 3 more discs, I may make one with only 3 or 4 blades so there will be twice as much down pressure per blade and see if that does any better, but that is leaning toward being counterproductive to my min-till plans.
I am going to work on making my planter into a min-till planter so I can leave residue on top to help control erosion and be able to plant right through it. I may need to chop the cornstalks with a mower if I give up on a disc so big pieces won't cause problems when I cultivate to keep weeds down. I'll just have to experiment to get a system that works.
