A cotter pin is a small but essential fastening component used to lock pins, bolts, or shafts in place and prevent them from backing out during machine operation. On ride-on power trowels like the CT36I and CT48I, cotter pins are used in high-vibration assemblies where secondary retention is critical — if a cotter pin fails or is missing, the primary fastener can migrate, leading to loosened components, accelerated wear, or mechanical failure in the affected assembly. Replacing a worn or damaged cotter pin with the correct OEM part restores the integrity of the fastening point and protects the components it secures.
