What the 100 is used for
The 100 works well for one-bottom-plough-scale chores, cultivation, mowing, and light material handling with suitable equipment. It is a focused row-crop machine rather than a modern general-purpose utility tractor.
Its open operator station, manual steering, and compact 71-inch wheelbase suit low-speed field and property work. Select PTO-driven implements with its modest power and drivetrain layout in mind.
Why the Farmall 100 stands out
Built in Louisville, Kentucky, the Farmall 100 uses the C-123 petrol engine and a straightforward four-speed drivetrain. The row-crop configuration and Fast Hitch are its defining practical features, while the 100HC was the high-clearance variant.
Buying a used Farmall 100
Inspect the Fast Hitch carefully for wear, damage, and missing parts, then verify that it matches the implements you expect to use. Check engine oil pressure and cooling condition after warm-up, inspect the 6-volt starting and charging system, and test every gear, brake, and hydraulic function before purchase.
