When the sun is up and the field work can't wait, your tractor cab becomes one of the most demanding work environments on the farm. Without proper AC, internal cab temperatures can exceed 100°F — creating real risks of heat exhaustion, dehydration, and costly operator mistakes during your most critical windows.
Our Air Conditioning Conversion Kits are built to solve that — without the price tag of a new machine.
❄️ R12 to R134a Refrigerant Conversion — If your tractor runs on R12, it's time to convert. Our kits include all necessary seals, hoses, and dryers to bring your system up to the modern R134a standard — legally and affordably.
🏗️ Complete Retrofit Kits — No AC at all? We carry full roof-mounted and interior evaporator systems with condensers and all plumbing needed to build climate control from scratch in an open cab.
