I bought a John Deere M2 two bottom plow for a John Deere Model M tractor At some point in time, someone welded an extension onto the plow share (see attached picture). It was only installed on the front or leading moldboard. What would be the reason for putting this extension on? How does it impact actual plowing? As I restore this old plow I am thinking about cutting it off to go back to original.
 
Trying again to post picture!

He may have had the plow misaligned behind the tractor (too far left) and it was leaving an uncut strip. Normally the share goes beyond the moldboard a couple of inches, but that is excessive.
 
I agree with JMS, that's what probably happened, before you cut it off u better see, how it fits behind your tractor.
 
It was somewhat common when rebuilding a share, the strip used to create a new cutting edge was left an inch or two long on the wing end of the share. This was done on both shares and was done for plowing alfalfa to prevent alfalfa roots from slipping by the end of the share. Perhaps, one would think this would need to be done to a greater degree on the front share because of error in driving the tractor. But, I agree that looks excessive.

The moldboard looks interesting. Looks like an "SP Blackland-Rice" bottom. Are you from east Texas or rice country in the south?
 
Yes it is an SP-212 moldboard. I picked up the plow in central Texas near Waco.

Thanks to all for the input.
 
yup, Id use it before id cut it off. Might be benificial. I cant see, tho, what keeps it from being bent while in use.
 
Not sure what keeps it from not bending as they welded on 8" of an old share with no back support. I did plow with it and everything did seem to work fine.
 
I have a parts plow that was for an M tractor. I think I have 1 or maybe 2 good shares, let me know if you need something! Bryce
 
Where it is mentioned about not having plow aligned correctly behind tractor and doing that to make it cut. The M was a single row tractor and narrow acording to the MT that was a 2 row tractor and they made different models for each due to wheel tread. So possibly someone had tried to use a plow for the M on a MT, hit same on both and that would be reason for not cutting but then it would be trying to turn a way wider furrow slab with the front bottom than what it was supposed to do and be too wide a slab to fal in the furrow from the back bottom the next time around. And if polw was put back on an M that welded on piece would just make plow pull harder as in the narrower tractor the fidth of the furrow slab would stay same as for from factory. Just somebody trying to cobble up something to make half work instead of getting correct unit.
