A steering wheel spinner knob (also called a brodie knob or suicide knob) that clamps onto the steering wheel rim to allow one-handed steering control. Used on tractors, forklifts, and agricultural machinery where the operator needs a free hand to operate implements, PTO controls, or hydraulic levers while manoeuvring. The spinner rotates freely on its mount, allowing the wheel to be turned quickly with a single hand in either direction without losing grip.

Fits most standard steering wheel rim profiles via the adjustable clamp mount. Not intended for use on road-registered vehicles in Australia — check local regulations before fitting to any on-road vehicle. Suitable for tractor and agricultural use where one-handed operation is a normal working requirement.
