plow "trash clearance" ?

Which AC plow would have the best "trash clearance" for corn stalks.  I am planning on putting in corn on 4 acres this year and then after harvest putting in wheat afterwards.  I would like to plow the stubble down as I don't have a no till drill.  I tried doing this a few years ago and plowed with a #53 and fought the plow the whole time (plugging).  I had good results with the wheat, but plowing was enough to pull hair out over.  I have a 190 with snap coupler and have been looking for a 4-5 bottom for it.  Any better series than the 50 series?

One very important thing to consider is to plow in the same direction the stalks are leaning, or pick the corn in the direction you want to plow. This will help lots for trash flow. Plowing against the stalks will learn you new words real quick. Make sure the coulters are set correctly. Sorry I cannot help with which model is best for clearance. Wider cut will be better. Rob.

I disk mine first with an A-C 2315 disk, which isn't heavy enough to chop the stalks very well, it mostly knocks them down. I then plow with D-15 and #82 slat-bottom plow. It has more clearance than your 53, but I would think that if you get the stalks knocked down, and your coulters are in good shape and adjusted properly, you should get through with minimal plugging.

Adam - 70 & 80 series will be much better than you 50 series.  My rotation is corn then beans then winter wheat/double crop beans so I never need to rush to take care of the stalk stubble for winter wheat.  I like to disc the stalks once in the fall then once or twice again in the spring unless we use the field for plow day.  My experience with 74 series fully mounted plows is the SC version has a little better trash in stalks than the 3 point.  I had to take off the front coulter on my 3 point version, even in non-corn stalk fields.  If it plugs real bad, just take them all off. 

Brush hogging first before any discing is even better and for 4 acres it wouldn't be much work.  If you have lots of acres you'd need a big batwing to be efficient.  Mike

I will readily agree that the 70 series and later plows will have the best trash clearance of the SC plows, and that shredding or disking are a great help when plowing stalks.  However, I firmly believe that good (not worn), sharp, properly adjusted coulters on a good (not worn) plow that is properly set are a real life saver in trashy situations.  The coulter must be large enough that it can be set deep enough to cut the trash, but still shallow enough that the trash doesn't bunch up in front of the coulter.  In stalks, I will often set my coulters to run just a little (~1/4") to the right of the leading edge of the shin.  In the fore/aft direction, I set them back until they run about 1/2" ahead of the shin.  This serves as a fence that keeps stalks from bridging between the bottoms, and makes sure they are cut just before they are turned under.  Notched coulters are a big help on plows that use smaller diameter coulters, but they still need to be in good shape.  Concave coulters will also help with low clearance plows, but they have to be in good shape and set properly too.  Going to the field with a worn out plow is like going on a moose hunt with a dull skinning knife.  Enough soapboxing from me...
