JERRY M. - Matt's correct, Several people here, namely Steve B. (Mr. PLOW), Wyatt Compton, and I think Art Atay, and maybe several others have modified Brinley plows to work better in high trash conditions. They've knotched the coulters, moved them forward, made scale-sized cover boards, and they can actually run in standing corn stalks if they want to.
A un-modified Brinley will handle chopped bean straw, chopped with the straw chopper on the back of the combine. But the whole plow frame just isn't big enough to handle a lot of trash. The last plows made by IHC in Canton had something over 30 inches of distance under the beam and between the bottoms. The whole Brinley plow isn't that big. The last plows IH made have the reputation of being some of the best moldboard plows ever made, the 710, 720, & 735 semi-mounted auto-reset plows were the most popular plows ever made before no-till became the way farming was done.
Having learned how to plow with an IH #8 3-14" plow behind a Super M-TA I know way too much about digging trash out of a plugged-up plow. In order to plow corn stalks from 100-120 bushel/acre corn You had to chop the stalks, and disc them at least once if not twice, 2-3 more trips over the ground. Letting them "Winter", get beat down by snow, wind, & rain from Nov. till April helped but didn't stop all the plugging. Dad tried every type of rolling coulter available and the knotched coulters worked the best. He also tried larger smooth coulters, rippled coulters, and concave coulters shaped like a disc blade.
The owner's and set-up manuals for IH plows gave pretty good starting suggestions for plow set-up. The coulters needed to run about half the depth of the plows, and just outside the side of the moldboard. A BIG cresant wrench, 2# ball peen hammer & a putty knife should be Your constant companion when starting to plow with any tractor/plow combination. And if You can't see Your reflection when looking at the moldboard of a plow You don't stand a chance of getting the bottom to scour, it'll pull REALLY hard. I always either smear grease on the whole plow bottom & coulter or spray a coat of IH Till-Coat on the bottom when I take my plow off. Makes it much easier to scour next time.
