Will be pulling them with a 1957 to-35 ferguson.
My friend who is a retired farmer said he never saw a two plow 142, he thinks they have been cut down from a 4 or 5 plow unit.
A good point I will have to ask about that because if I do not have the last plow furrow guide they may not work right. Also the crossbar may have larger size pins.
Maybe I need to look else where for a plow but I wanted 16" for the larger throat size.
