Kubota Suicide Knob & Deluxe Wheel Spinner: Fit Guide

“Kubota suicide knob,” “kubota deluxe wheel spinner,” and “kubota steering wheel spinner knob” all describe a rim-mounted spinner that lets you turn with one hand on tractors, mowers, and some utility vehicles. The “suicide” nickname is historical slang — modern equipment knobs use solid clamps and are meant for farm and yard use.

Deluxe wheel spinner listings usually mean a larger grip and metal hardware versus a bare plastic ball. Focus on clamp range and build quality, not the marketing name. Measure your rim thickness (often ~1"–1.2" for Kubota-style clamps).

Install on a clean rim, seat the clamp fully, and re-check after the first hours of vibration. Never mount over an airbag cover on road vehicles, and confirm local rules before street use.

Farm, lawn tractor, zero-turn, and forklift rims are the sweet spot. If the knob creeps on a soft cover, add the friction pad or choose a different clamp — don’t overtighten until the wheel cracks.
