Control lever knob 128/C0600 JCB 3CX/4CX, aftermarket

Control lever knob 128/C0600 is an aftermarket part for the JCB 3CX and 4CX backhoe loaders.

The control lever knob is the grip the operator holds when working the backhoe or loader levers. Its shape reduces hand fatigue over long working hours, and it is screwed or pressed firmly onto the lever. A loose, cracked or worn knob makes precise control harder, and the hand may slip and cause an unwanted movement. A missing knob leaves the sharp end of the lever exposed. The knob is ergonomically shaped for the operator's hand and stops it slipping during work. If the knob has buttons, their wires are connected carefully. The thread or pin holding the knob can loosen over time, so the knob is checked regularly. Any rust on the lever end is cleaned off before the knob is fitted. Keep the knob clean.
