[Farmall] McCormick-Deering 10-20 Engine Serial Number

[john hall]

Ben, the early 10-20's had a large water bath air cleaner. They also used a 
different exhaust setup--there may be a difference in the hood to 
accommodate this.. They also used Splitdorf magnetos. You can use that as a 
reference when the serial # can't be found. I'm pretty certain 10-20's also 
could be built with v shaped lugs instead of angle iron cleats. I don't know 
if they were options or if it was a design change.


You may have been hearing a mouse nest in the clutch. Its amazing what they 
can haul in there.

To my knowledge there were no wheel set-ups with tread bolted on. Industrial 
tractors could have had hard tires cast/pressed on (like on a forklift). I 
don't know if these were offered on a standard 10-20, probably not.
