When the switch fails, you lose that ability to match your cab environment to the conditions, and suddenly those long winter days become a lot more uncomfortable. This universal replacement knob gets you back in control of your heating system so you can focus on the work instead of wrestling with broken controls.

Built for Real Farm Work
This knob works with common heater control switches you’ll find in cabs across different tractor brands. Whether you’re adjusting heat while plowing through morning frost, cranking up the defroster to clear fogged windows, or finding that perfect temperature for those long days in the field, this knob handles the constant adjustments that come with changing conditions throughout the day.
Made to Last
These stopper knobs take more abuse than you might think – constantly being tightened and loosened, exposed to sun and weather, handled with greasy gloves. This replacement uses quality materials that resist stripping and wear. The design holds up to UV exposure through cab glass and won’t crack when you’re turning it with cold hands on below-zero mornings.
Good to Know
Check your switch numbers before ordering – this fits switches 64415 and 43163 specifically. Clean any old plastic bits off the switch shaft before installing the new knob. Push straight on to avoid cracking, and test through the full range to make sure it’s seated properly. Many farmers order several of these inexpensive knobs at once, keeping spares in the toolbox. They’re also handy for other applications around the farm where you need a quality control knob.
