Overview
An owner-operator documents the first step toward pulling the oil pan on a vintage John Deere 420 crawler: removing the front skid plate. He explains why he's doing it (sludge found in the oil pan), walks through the bolts and hardware involved, and hits an unexpected snag with the drawbar attachment. Casual and unscripted, useful mainly to other 420 crawler owners tackling the same job.
Posted by the Gotwoodinhead channel, which appears to be an individual owner working on their own vintage machine, based on the informal first-person narration throughout.
