Built for Classic Farm Work
Your 1960s Fordson Dexta or Super Dexta might be decades old, but it’s still earning its keep around the farm. These 35-45 HP tractors are perfect for winter tasks like hauling hay, pushing snow, or running to check livestock. The factory heater system makes these cold-weather jobs bearable when everything’s working right—but after all these years, switches fail from corrosion and worn contacts.
Made to Last
This isn’t some complicated electronic module that’ll leave you stranded. It’s a straightforward switch that sends power to your heater motor when you need warmth—nothing fancy, just reliable operation. The internal mechanism gives you positive engagement so you know it’s on or off, and the electrical contacts are built to handle the load without burning out.
Installation Notes
Most folks can swap this in about 20 minutes with basic tools. Access is usually through the dash panel, but be gentle with that old plastic. Always disconnect the battery first, and label your wires if you’re not sure which goes where. While you’ve got things apart, check your heater motor and hoses—a new switch won’t help if other parts have failed.
