I have been doing some more research on Massey plows lately mostly trying to figure out all of the different tractor plows that Massey offered. In my search there is a couple I have never heard of before and several I have never seen existing. If anybody out there can help me out in identifying more models of plows or the differences in some off head that would be great.
Here's my list so far
MH power lift tractor plow (chain lift plow 1918-1930, updated from #5 horse drawn gang plow) probable affiliation with Grand Detour on the design.
MH power lift tractor vineyard plow
MH orchard special tractor plow
#3 2-3 bottom, JI Case plow works design
#4. 3-4 bottom, JI Case plow works design.
#5 2 bottom, looks like a cheape version of #3
#6A 2-3 bottom, advertised as heavy duty "western" plow
#9A #9B 2-3 bottoms. Two clearly different plows between the A and B.
#18A 4 bottom plow. Very similar to #6 with very little information to be found so far.
#19 2-4 bottom also similar to #18 and #6.
#21 I have no info on this besides a listing in the 1941 handy catalogue for replacement shares.
#23 also no info like the #21
#25 same as the last two no information right now
#26 2-3 bottom adjustable width.
#27 2 bottom
#28 2-5 bottom made from 1941-1958
#90 2 bottom light duty, sometimes advertised as a fordson plow.
#4 grub breaker plow, heavy duty 1 bottom breaking plow.
I have not written down the numbers for all the mounted and semi mounted plows yet so I am consentrating on the pull type tractor plows.
