I know I'm aging myself here, but back before all this modern day farming came about, to prepare a field we would start out with a disc to break open the soil. The idea of disc-in first was so when you came in with the plow it rolled the soil over better and there weren't big chunks.
We would first go length ways then the short way.
From there we would plow the field with a five bottom on the 856, then disc the field again length ways to level it and fill in the dead furrows, and then the short way.
Follow that up with the drag, long, short, long way and your field was prepared for planting.
I know you young guys think that's a lot of "farting around" but it made one beautiful, smooth field. Sure it was time consuming, but that was OK, because I was making $1.50 an hour
I still think a disc is all about the set up more so then weight.
