sickle bar mower adjustment & mowing under fences

This is a mechanical deep-dive on sickle bar mowers, not a tractor review: Pete uses an International C21 mower behind a 1953 Farmall Super C to explain drive pulleys, slip clutches, pitman drives, knife sections, ledger plates, and hold-downs, then demonstrates proper adjustment and actual fence-line trimming, including a clog and mower trip. Best for owners maintaining or adjusting an old sickle bar mower, not shoppers comparing tractors.

An experienced hands-on farmer sharing detailed maintenance knowledge from his own equipment and years of use, not a dealer or reviewer.
