IIf you have a tractor then the chances are 95% that you have broken off a Zerk. Keep that EZ-Out with your Zerks for future use.
The remaining 5% never have greased or are outright liars. :laughing: :laughing: :laughing:
That may be true for newer tractors using pot metal zerk fittings. Older tractors from the 40s, 50s, 60s (A-C, Ford, JD, etc.) used real metal in the zerks, and they didn't break off unless seriously abused. I keep some NOS US-made Zerk fittings for replacing them on newer equipment when they inevitably break off after the third use.
