Tractor Trivia – Finding Serial Number on Massey Harris 33 & 44

MH 33 & 44 Tractor Serial Numbers – In addition to the serial number plates frequently missing from the frame rail behind engine, the serial numbers are steel stamped into the frame / top of transmission about where driver's left foot might rest. Frequently these areas are covered with grease, dirt, and/or paint, but serial number will be there. It may be in 2 lines with designation such as 33G1RF above the actual serial number.

Common designations are:
G=Gas (vs K=distillate or D=diesel or B=LP)
1=Sea Level (vs A=altitude or 5=altitude 5000 feet)
R=RowCrop (vs S=standard or W=wide front or O=Orchard)
F=Foot Clutch (vs H=hand clutch)

Not all codes were used on all tractors and designations as W could also be Wheatland on a 555, etc.
