Serial Number Location:
For Case 680L models (produced from 1994 to 1996), the serial number plate is typically mounted on the left side of the frame just behind the front loader arm tower or stamped near the rear of the transmission housing. Always confirm the serial number before ordering to ensure part compatibility—especially with hydraulic and transmission components that varied between early and late builds.
