Description
When you’re in the middle of harvest and your combine starts running hot, you need that cooling fan to kick in right when it should. This thermostatic switch does exactly that—monitoring temperature through its long capillary tube and triggering your fan when things heat up. With harvest windows being what they are, you can’t afford to have cooling issues shut you down when there’s grain ready to come off.
What You’re Getting
- Rotary adjustable control lets you fine-tune the temperature setting for your specific conditions
- 36-inch capillary tube reaches wherever you need to sense temperature in your combine
- Built to handle the vibration, dust, and heat cycles that combines dish out
- Direct replacement that works with your existing wiring—no modifications needed
Built for Real Farm Work
This switch is designed for the workhorses of harvest—the Massey Ferguson 8560, 8570, and 8590 combines that power through everything from wheat and corn to soybeans and barley. These big machines generate serious heat when they’re working hard, and proper temperature control keeps your engine running strong through those long harvest days.
Made to Last
TISCO builds this switch to agricultural standards, not automotive ones. The capillary tube is flexible enough to route where needed but tough enough to resist kinking or breaking. Internal components are designed to handle thousands of switching cycles without losing accuracy.
Good to Know
The rotary adjustment makes it easy to dial in the exact temperature you want—handy if you’re working in different conditions or want to fine-tune performance. Mount the sensing bulb where it’ll get good airflow but won’t get damaged by moving parts. The 36-inch tube gives you plenty of reach for most installations.
