Engine Serial Number Location:

Typically stamped on the engine block, often near the front or on the side. Consult manual for precise location.

🔧 Transmission

Transmission Type:

Case David Brown's own transmission, often a 12-speed constant mesh gearbox with 4 main gears and 3 speed ranges, plus reverse. Some models may have offered powershift options.

Optional Transmission:

Powershift or synchronized shuttle options may have been available on certain configurations or later models, but the 12-speed constant mesh is typical for this designation.

Pto Speed:

Standard 540 RPM and/or 1000 RPM PTO, with options for ground speed PTO.
