County Four-Drive (1954–1958) – British four-wheel-drive machine from the farm- and construction-equipment maker County, with a water-cooled diesel engine and the County Super-4 as its successor
County was an English manufacturer that built tractors and machines derived from them with permanent four-wheel drive, at a time when most comparable machines drove only the rear wheels. The Four-Drive recorded here was built from 1954 to 1958, placing it in an early phase of this four-wheel-drive technology before the company developed the range into the County Super-4.

The Four-Drive is powered by a water-cooled diesel engine whose output reaches the ground through a drivetrain with four driven wheels (4WD). This permanent four-wheel drive was the key difference from the standard two-wheel-drive machines of the period, and the reason County machines could develop extra traction on difficult ground.
The four-wheel drive made the Four-Drive suited to tasks where simple two-wheel-drive machines reached their limits: on loose, wet or uneven ground on building sites and farmland, where the added grip of the front wheels reduced wheel-slip and soil compaction. Its succession by the County Super-4 shows that the company pursued this drive concept consistently.
On such an old four-wheel-drive machine, the condition of the transfer case and the drive shafts to the front axle matters most, since these components are placed under particular strain by permanent four-wheel drive. The engine, cooling system and axle seals should be checked for leaks, and spare parts for such a rare range, discontinued decades ago, can practically only be sourced through collectors or custom remanufacture.
