Plow cat 1 drawbar pins too short

A good solution IF removing all the adjustment of the plow is not important and the welded drawbar happens to be exactly where it needs to be. That would be "the luck of the draw" if it is.
In the second pic, shows all the tilt and angle adjustment that is built into the original plow part that was removed. Some of the cheaper plows on the market forego that feature, and must be devils to get to get the plow set for good plowing.

But proof will be in the plowing when up and running. Hope it works well.

The 3PH on a M7040 is adjustable several ways so that the adjustment feature on the plow is not needed. The stock angle adjustment was very slight and just alters the "attack angle" of the plow. Presumably that function is used if a light tractor is pulled a bit out of line by the twisting action of the plow. The same thing happens with a 3 PH offset disk to an extent.

The placement and relationship of the original pins on the plow is what determined the placement of the drawbar when it was welded on. The bottoms are aligned to make the second cut run with the tires in the furrow.

The Top & Tilt makes adjusting the plow a breeze to do on the fly to make it cut perfectly. Thus the offset when running in the previous furrow is a function of the adjustment of the 3 PH rather than the pins on the plow.

It seems like those old plows were made when adjusting a 3 PH was not so convenient or even possible.

I got tired of thinking about it. I just wrapped a chain around the lift arm and secured with a chain binder. A few acres later it's holding up great.

That works. A true "farm fix".

I have an (old) MF 14-inch two bottom plow with a cat 1 offset drawbar... The pins are too short to accommodate my cat 2 lift arms on my three point. Pin diameter's not the issue I have bushings etc. These pins were made unusually short for category 1. Any suggestions, or anyone else ever encountered this one? Thanks.

We run into this quite often and the easiest way to remedy the problem is with a angle grinder and grind back the shoulder enough to get in your lynch pin and slip over your step up bushing. Do this procedure and you don't have to worry about how to adjust your angle. Ken Sweet

That was the best solution I could come up with as well. Originally, when I posted the question, I was hoping someone would have an adapter of sorts. But it looks like that's not the case.
Thanks for backing me up Ken.

You are welcome. Good luck and happy grinding! Ken Sweet
