Middle buster

My 2300 Disc has one. It's used to break up an undisturbed, narrow slice of soil that the front gangs leave, prior to the rear gangs passing over it.

Poor man's potato plow, or used to cultivate between wide rows.  Some subsoilers can be bought as a subsoiler with optional accessories, like the MB or a pipe layer...

I agree with Jim in OH, always thought that was a (middle buster), it is called that in the owners manual.

Thanks for the information guys very much appreciated.

Wow! Do we simultaneously talk about 2 different things much?!

Hey Tbone95, wanna start a third? 

Then there's the opposite of what Shameless said...insitead of planting on the hill they made, out in western Oklahoma/Texas and other dryland places, they used lister planters and planted cotton/milo in the trench the middlebuster left behind. Had to try and catch any rain that may come.

Decades ago, before fertilizer and hybrids, two middle busters (aka listers) were on 42" centers and dug a 7" deep furrow which also resulted in a 5" high ridge.  Row crop like corn and milo were planted in the bottoms of these furrows/ridges. As the crops grew cultivator shovels scraped these ridges into the furrows resulting in elimination of the resulting young weeds and covering the crop seeds and plant roots now being  7"+ deep. Winds had to become very severe before they adversely affected the well rooted row crop plants.  Also the weather had to become very dry before it affected roots that were 7"+ deep.  In central Kansas this all changed with the advent of fertilizers and hybrids; about the time I graduated from school and did a hitch in the Navy; then left home.  Dad made good money raising 40 bushel/acre corn.  Today two big quarter mile radius irrigation wheels dominate our old half section farm.
