 Topic: Question about a plow
Posted: 28 Oct 2016 at 12:34pm |
See attached picture. the plow in question was sold at auction last week.  The plow is a roll over but it is snap coupler with two hydraulics which means it would work on a D-17 Series 4 or a D-19. But if that is the case should it not be a 80 series plow with spring resets on the bottoms.

Spring trip with adjustable width could be a 80. There are parts pictures in the plow frames book linked over on the Knowledge Forum under AC Plows Parts 101. In that parts book for plow frames there are also kits to convert 60 and 70 family plows to spring trip.

A lot of the earlier plows could be adapted to later options, the plow frames were the same, as the early ones...

I think the 60, 70, and 80 plow frames where contemporary, not early to later. The 60 was the plain frame fixed width and shear bolt shanks. The 70 was almost the same except for the adjustable width frame. Two piece cross members and a few extra bolts instead of one piece cross members. 80 used the same 70 frame parts but came with spring trip shanks. 60 plain, 70 a few more parts, 80 handier to use in tough conditions. With the spring trip kits the 60 fixed width frame stayed the same but putting those kits on a 70 can't be told from a factory delivered 80 family plow frame unless there was a model indicating decal that has survived.

Thank you that explain alot that about the shanks and the frame of the plow the bottoms had 373 sticker on them. But that still leave one question how many two way hydraulic roll over snap coupler plows were made see attached picture  Note this estate sale was a for former Foreman from the Laporte Allis works

In the plow frames parts book the hitches are separate from the frames. The bottoms are in a separate book. I believe ordering a plow started with choosing a size, then the shank options, then from a separate list the hitch, and then from another the plow bottoms. Seems like all AC bottoms use the same mounting bolts so any bottom fits any plow. Its hard to know how many were made and sold.

The 70 series plows were also an inch taller and longer between bottoms than the 60 series for more trash clearance.

Most problems can be solved with the proper application of high explosives.
