I agree that a disk has a shearing action to it as the soil is moved and a true VT tool does not.  However, as an example I picked two similarly sized tools that are popular in this area:

Great Plains 30' Turbo Till - 179 lbs/blade

Krause 31' 8200 series medium duty disk on 8" spacings - 174 lbs/blade

Plus most turbo tills around here have the optional weight package on them raising the lbs/blade even higher.  So how do they not compact?  How are they better?

BTW, I'm not trying to promote a disk over a VT tool, our disk is regulated to corn stocks (LOL) in the fall. I just don't have my head wrapped around why the VT tools that are so popular (and very $$) are so much better than a disk.  We have a true VT tool and you can go fast, it levels perfectly, and you can cover a lot of ground in a day,  All of which are very good reasons to run one, I just wonder if the rest of the purported claims are marketing.......mark



I expect the shape of the con caved disk creates more of a compaction layer. But using your example to go along with my original question. Would the Krause disk actually have 174lbs/blade if it wasn't going as deep as possible with the weight being carried on the disk tires? If the tires weren't touching the ground that would be a significant increase in compaction.
