Looking to buy a set of moldboards for my oliver plow but I am not sure whether to buy 16" or 14". Its currently set up for 2-16s but I am thinking of changing it to 3-14s. Can I use 16" moldboards with 14" shares if I decide to change the plow around and add the third bottom or does a 16" board restrict me to the 16" configuration? Thanks,

Depends. Do you have a 14" and 16" board you could lay against each other and examine the differences? If, to make the 16" board, Oliver just added a little height or a little length to it compared to a 14", I would use a 16" board. If Oliver did something else, like making the curved tail of the moldboard higher, changed the curvature at all, I would shy away from using the 16" board to cut 14". I would pick a width and stick to it, in that case. Shares aren't a big deal: cut 14 with a 16, or cut 16 with a 14: manufacturers offered over cut, full cut, and under cut shares for different purposes years ago.

Personal experience:
I tried to use a 16" IH Plow Chief on 14" spacing for a few years and wasn't happy how the furrow slice turned over. After inspection, I realized IH took a 14" board and "rotated the tail up" to make a 16" board. So, when plowing on 14, the soil never got high enough on the curved tail to get turned over properly, and the top of the tail was never scouring because the soil didn't get up there to clean it off.
And recently, I messed with MM general purpose "CY" bottoms. After measuring, I discovered MM added around an inch to the tail to make a 16" board, but they also "pushed the tail ahead", which turns over the soil more aggressively. Not good for heavy land or sod. I settled on using the 14" board and always using a moldboard extension.
