I'm just assuming you need shares & moldboards. Open this link to New Holland Ford for a complete list of parts along with exploded view of your plow:
Dearborn 12'' Plow | New Holland Agriculture | MyCNH US Store Select a function group, and select it, it will open to an exploded view, and part numbers associated with what part you may be looking for.
The easiest way to find parts is to copy and paste the OEM part number listed with item and use Google to search for them. Looking at the exploded view of the moldboard and shares you'll see in the "alts" column, and a square box with an arrow in it. Select that, and another window will appear. To the right is an arrow pointing down, select that, and it will show an alternate part number. Another window will open to find your nearest New Holland/ Case New Holland dealer. Once you select that, it will revert back to the part you selected and show the price. I did that for the share, and it is still available through New Holland, but is $217.00.
Another option you may try first is to call a place called Ploworx here in Ohio up near Salem, Ohio. He makes many plow shares and moldboards that are now obsolete:
Ploworx Custom Plow Parts, Salem, OH, USA His webpage is very incomplete, but the phone number should still be good. His wife passed away several years ago, and I assume she was putting the web page together but passed before completing it. Fair warning, call when you have a little time as he is a talker. He may very well have the shares and moldboards if that is what you're looking for. If he doesn't have them, he may be able to steer you in the right direction.
If that isn't what you're looking for another option would be to list a free "want to buy" ad on TractorHouse:
TractorHouse.com | New & Used Farm Equipment For Sale Look at the top right of the page in the menu and you'll see "Post a free want to buy" select that. Fill out the form with name and contact info, have your model numbers and part numbers you're looking for. There are many smaller salvage dealers and farmers that have parts for sale that don't list what they have on their site. It works much like the old teletype auto salvage parts dealers used, or similar to Junkyard Dog site that used to be up with auto/truck parts for sale.
I have gotten more than several hard to find parts for older tractors and machinery. But you must register and give contact info to prevent scammers from clogging the system. I have gotten replies in as little as 45 minutes of posting, to 3 days out. Beyond 3 days, there may be little hope, but you never know.
One last option would be if you have any Amish in your area that may handle plow parts. We have one up in Holmes County we visit at least every year on Black Friday on our annual salvage yard run. He literally has stacks of new moldboards and shares on pallets. I'm assuming he gets them from Ploworx. Wish I could remember the name of the place. He gives us a stack of calendars every year, but this year at the end of the day forgot to pass them out when we got home, and one fellow took them all home. Even at that, you'd have to write them as I don't believe they have a phone. But a very unique place to visit if you're ever up this way. I'll text a buddy that buys some items there, that place had 8" shares and moldboards for his IHC 8" 3 bottom orchard plow. If he had that, Lord only knows what all he has, or available to him.
