Notes
Guard for the 2-speed PTO on Allis-Chalmers 170 to 200 series tractors, including the 190, 190XT and 200 (also listed for the 7000). The salvage listing offers only a used shield at $89, marked unavailable to buy online, and sends single-speed owners to a different used assembly (70255996, $60, also used-only). No new version was linked. Recorded as evidence of demand for a safety guard that PorkForge will not make.
