Big 1 bottom plow(unusual)

thx for the picture s larry havnt seen any like that.

   That is a Breaking plow. They used them to turn over heavy virgin sod. I thnk that might be a Case.

Looks looks like an IH 24" brush breaker.  We had one like that when I was growing up.  Had the rolling coulter and also had a standing knife.  To use the knife you would remove the coulter and the matching share.  Then replace the share with one that fit together with the knife.  You would use the knife set up on ground that had been bull dozed and was full of rocks and tree roots.  Dad broke up a lot of our land with an IH breaking plow and a '38 Allis WC.  Lots of backing up and taking a run at it when you got into some tough tree roots or rocks.  All low gear work.  I was there watching and also helping.  Yup, those were the good ole days!

hello Larry!!  I have one that looks just like it, it's an IH. we used it last year behind a d19D we knew it was there because when it got a little greasy the tires would spin.  The plans are to use an "M" or "KO" crawler.   Allen

The plow next to it, I am guessing an oliver?  The long cylindrical thing, is it just a heavy chunk of steel or a tank of some type? 

Gerald, I doubt that moldboard length in itself has anything to do with the draft of a plow.  I will use a kerveland(SP?) as an example.  These european plow bottoms are being installed now on new manufacture one horse drawn plows produced by a company in ohio named pioneer.  They also offer JD bottoms or Oliver/Radex bottoms on the same plow/frame.  The Kerveland takes the same amount of cut (14") as the radex and JD bottom but the moldboard is nearly twice as long.  Yet a plow equiped with this bottom pulls nearly 20 percent less draft than the others which is huge when you only have 2 hp.  In sod and corn ground this bottom is spectacular as it flips in completely over and sets the cut side by side instead of on edge at a slant.  In bean stubble it did comparably with a radex bottom.  

The reason it pulls so much easier is more due to the geometry of and design of the point and share.  The point is a replaceable and indexable bit not unlike a large lathe bit, made out of a high carbon steel.

I have been told that the kerveland bottom pretty much has won the world plowing championship for the last 20 years, sometimes on kerveland plow frames, sometimes on other makes of frames. 

I want to recall someone on here had their bottoms on a snap coupler competition plow?

pioneer manufacturing is about 20 minutes from me.  Most all the amish around here, and we are only second to Lancaster PA, use pioneer equipment.  They make plows and powercarts as the main line.
