If you are restoring a 336, John Deere can print a "build sheet" for your specific serial number if it is above 200,000 (their digital records improve after 1978). This sheet tells you exactly how the baler left the factory: what color (Classic Green or the rare Buff/Yellow), what twine size was calibrated for, and which options (like bale thrower) were installed.
Without a serial number, you must order parts by description. However, be warned: the knotter for a 1969 336 (using a D4620 knotter) differs from a 1979 336 (using a D5133 knotter).
