How do you break the end of a moldboard?

[Fred from MO]

I posted the other day questions about a plow I have (new to me). It has 2 moldboards out of 3 where the trailing end of the moldboards are broken. How would this have happened. Is it common or was it from abuse? Middle moldboard is ok out of the 3 and the outer moldboards are busted. Sorry the shadow in the picture hides a little of what I was wanting to point out.

Could have it a large rock.

Abuse.Someone simply backed into something or ran into it with some thing.If you have the pieces,you can repair them.When I was a kid,my father once 'tossed' a two bottom Ford plow from his pickup.It hit on the end of the moldboard-snapped like glass.Dad welded it back together and used it for several years.

That is about the least stressed part of the molboard, so would be a very unusual thing to have happen in normal plowing? Unless the molboard is worn paper thin or something?

BTW,those look like IH Super Chief bottoms.They are still available...

My dad did that to a plow I have. He hooked a chain around it to pull something and broke the mild board in half. Of course in this start it could well happen by hitting one of them small rocks you find once in a while

my grandfather backed our Dearborn into a corner post when he was turning around...he had somebody weld it back in '65 or 66...i'm still using it.

I saw a three bottom that had all of them broke that way at the sale in Archbold one time. Figured it had to have happened in transport on the way to the sale. They'd made some attempt to weld'em back on.

I just bought a 3/14 Deere trailer plow and the guy said he hit a tree at the end of the field with the number one mold board and broke off the outside part like yours is in the picture.

Most farmers did what they had to with what they had available. They had no "gators" , skidsteers , Quads or any of the "toys" most farmers have today. Tractors and equipment did a lot more than they were designed to do. Also a lot of very young drivers back then on tractors that were not very "youth freindly" if ya know what I mean. Crap happens when ya mix all that together. Lot of old machinery being pulled very carelessly out of tree rows/fence rows for scrap and then sold to someone to use/restore. Well , dammage done now.

Looks like in the picture the moldboard brace is missing.Like the guys said,not uncommon to have these break from being hit,etc. The old cast parts were even more brittle,I"ve broken many a share from rocks back in the old days,when new shares were $6 each!! That should date them.

Welll, ya takes a board, an spreads some mold on it, like from an ol bale of hay or the barnyard. Then ya goes down ta town an gets one of them little Krean felllers whut knows karatee, an get him to Whack it onct or twice. They kin usually break em reel easy...or do ya call that a moldy board????

Probably got broken from back blow, not from plowing. I've plowed tough limestone clay with moldboard extensions and the boards would actually spring back without breakage - but don't back into a fencepost.

You back into something....

Probably abuse or not paying attention.

Years ago I picked up a C20 2pt fast hitch plow for my Farmall Super C. Really good shape. When unloading it my helper stayed on the joystick too long and the down pressure from the loader snapped the mold board in half.
