There was not a unique plow frame to be a SC for a B, nor unique plow bottoms for 12" to fit that frame. Identifying the plow model doesn't identify the plow bottom, nor the shear, share, blade.

Allis sold at least 4 different plow frame models in the SC era, and sold bottoms separately. There weren't as many 12" bottoms as 14 and 16" bottoms though.

Mostly the 50 series had a vertical plow shank and fixed frame width. The shank may have sheared bolts if it hit a rock hard enough. 60, 70, and 80 series had slanting shanks. 60 and 70 models had bolted shanks. 60 frame was fixed width, 70 and 80 adjustable width. 80 series came with spring trip shanks. Spring trip shanks to fit 60 and 70 series frames are in the vintage plow parts book. So they could be retrofitted in the field if a farmer wanted to update.

For nearly all the plow bottoms in the plow bottoms book there were multiple shares, shears, blades offered. Shares, shears, and blades are different territorial names for the same part, indeed in the plow bottoms book, some were called shares, some called blades. There were multiple shares for each bottom with different characteristics and materials. They were made of chilled iron which wore the best but broke more easily when hitting boulders. Some were made of steel hardened all the way through that didn't wear as good as chilled iron but survived some rock impacts. And then some were made of soft centered steel that were the toughest in rock impacts, but when the hard surface wore through the center wore very rapidly. Then there were wide cut shares, narrow cut shares, deep suck shares, and normal suck shares. Deep suck shares had a longer nose turned down.

There aren't good pictures to identify plow bottoms. The illustrations in the parts book don't show the variations in moldboard shapes between similar bottoms, but show the details looking into the frog from the bottom. Occasionally that view is unique enough to identify a bottom. The reliable way to identify bottoms and parts is to find an AC part number on frog, share, shin (if separate), or share. Landsides tended to be shared with many bottoms. You can list the numbers you find and we can look them up or you can download the plow bottoms parts book from www.grandpastractor.com/phpBB3/index.php where there is also a plow frame parts book to help identify the plow frame from details.

Plow frames for the various hitches were the same, just the hitch parts were different for pull behind, SC, and three point.

I need to make this into AC Plows 101 web page!

It seems, Grandpas-tractor-site has gone away. A plow parts manual is available for $80+ from a certain manual reproducing outfit.

Dennis Anderson put together this video to help ID different Allis plows.
