Introduced in 1934 as the sucessor to the "Corn Belt Combine", which used
a "brush" cylinder to thresh, the All-Crop Model 60 Combine was first known as the "High Speed Combine" and used
rubber faced cylinder bars and concaves. Full production started in 1935. Allis-Chalmers claimed one could
harvest 10-20 acres per day with its 60" cut. A two-plow tractor, or a tractor
with 20 hp or more at the PTO was recommended by AC to power this harvester. At serial number 86337, a hand crank was featured to allow easy cylinder speed adjustment as
opposed to replacing cylinder pulley spacers. Early units up to 23801 had a common clean grain and unloading elevator. In 1940, 250 special hillside units were produced.
The All-Crop Model 60A started in 1949 with serial number A101. This version had a few improvements, most noticable an auger in the inside of the grain tank to help unloading, and a
lever style engaging mechanism for the unloading auger as opposed to the previous dial style.
Like all the All-Crops the Model 60 was available in a bagger model and the cornhead built for the later Model 66 could be retrofitted to fit the 60.
As with all the All-Crops, an AC power unit, a B-126 for this model, was
available in lieu of tractor PTO.
All-Crop 60/60A Today
Since the model 60/60A was the most produced of all the All-Crop versions,
this model is the most numerous to be found. However, as with any equipment over 60 years old,
finding one in good
shape may be difficult.
