2012 Farmall C Demonstrator

As presented by Kevin Cotter for Credit River Tractor Club

Farmall C Demonstrator Manufacturer: International Harvester Factory:     Chicago, Illinois International Harvester 4-cyl gasoline

The Farmall C was produced from 1948 to 1951, when it was replaced by the “Super C”. Approximately 79,836 Farmall Model C tractors were manufactured. The weight of the tractor (without water or fuel) is approximately 2,780 pounds. In early 1950, a handful of these tractors were delivered to dealers with a white paint scheme as special demonstration models.

In 1948 the first Farmall Model C tractor rolled out of the factory and into the farmer’s field. A follow-on to the Model B, it was slightly larger in size but kept the same 113 CID engine and 4-speed transmission. Other upgrades included adjustable rear tire spacing (with sliding hubs), a frame design similar to the larger Farmall Models H and M, and International Harvester’s new “Touch Control” system which allowed the operator to lower and raise implements by touching one small lever. The tractor was very versatile and was used primarily on smaller farms or for small jobs on large farms.

Demonstrator white C’s, were produced during the 1st quarter of 1950. Since the records were destroyed during the Case/IH merger, no one knows for sure how many were produced, although the serial numbers for the C are thought to range from 47010 through 54411, or 7401 produced.

Wednesday night was a busy evening, I didn’t make it but I heard everybody pitched in and worked hard. Nust & bolts were sorted and the Farmall C Demonstrator was pushed into the shop Wednesday night and work started. The Disassembly/Reassembly Team has most of the tractor apart already.








Here’s the cylinder head removed. Note the creative use of washers used to keep the valve springs tight, this engine was in serious need of a rebuild.

Engine Team – Lloyd stopped by and pulled and dismantled the engine Thursday afternoon. The block needs some welding done, it isn’t cracked but a support hole for the front end is broken. Bill ran it down to Mankato for the welding; it should be back sometime Friday. Lloyd checked the crank with his micrometers and ca‬lipers and pronounced it good, just needs a good polish and some new bearings.

Pat and Brady begin to rip the transmission apart.
