Yanmar Tractor SA424 Throttle Friction Disc Adjustment [EASY DIY]

An owner-operator who has run his SA-424 for five years and 230 hours walks through fixing a throttle lever that wouldn't hold RPM. He shows exactly which dash panels to remove, names every bolt size (10mm, 14mm, 24mm), locates the friction disc under the steering column, and explains which nut to tighten. Best for SA-424 owners facing the same creeping-throttle symptom who want a confirmed DIY fix with the actual tools listed.

An owner-operator sharing a real-world repair from his own machine, with no apparent dealership or brand affiliation evident from the transcript.
