Description
Overview:
The Knob Throttle is a non-genuine replacement control knob for JCB backhoe loaders and excavators, including the JCB 3CX and 4CX. It fits the hand throttle assembly to let the operator set engine speed accurately for digging, loading, roading, and auxiliary hydraulic work. Made from hard-wearing plastic with a practical grip profile, it withstands daily use in tough site conditions. This replacement matches the function of the original part it replaces (JCB OEM 331/30884) to restore smooth, precise control where the original knob is worn, cracked, or missing. Suitable for a wide range of JCB machines listed below, it helps keep your cab controls consistent and easy to use, supporting reliable engine speed adjustment across varied tasks.
