All-Crop Harvester
Encyclopedia
All-Crop Harvester, or All-Crop Combine, was the name of tractor-drawn, PTO-driven (except the All-Crop 100 and the All-Crop SP100) combine harvester
s made by Allis-Chalmers
from the mid 1930s to the early 1960s. Aside from small grains, these harvesters were able to harvest some flowers, as well as various grasses and legume crops for seed.
The first combines under that name, the All-Crop 60, had a 60 inch, sickle-bar cutting head, and the popular Model 66 had a 66 inch cutting head.
Many of these units are still in working condition, and they are well-known for their dependability and low maintenance; however, as they are quite small machines (and now very old), they are not practical on today's large farms. They were superseded by the Allis-Chalmers Gleaner combine harvesters.

All-Crop 40
Specifically designed for the Allis Chalmers Model B and C tractors, this model had a 40-inch cut and could harvest approximately one acre per hour. Produced from 1938 to 1940; only about 15,000 made.All-Crop 60
Five foot (60-inch) cut; replaced flat belt with Texrope V-belt system. Produced from 1935 to 1949, with over 100,000 produced, this was by far the most popular All-Crop model. Harry C. Merritt and Charles J. Scranton each earned the prestigious Cyrus Hall McCormick MedalCyrus McCormick
