Built for Real Farm Work
This switch is designed specifically for the popular Massey Ferguson 5400, 6400, and 7400 series tractors. Whether you’re running a 5425 on a smaller operation, working mid-sized acreage with a 6470, or handling big jobs with a 7490, this switch gives you safe control over implements that depend on PTO power, allowing you to engage only when ready and disengage instantly when needed. These tractors power everything from hay balers and mowers to feed mixers and manure spreaders.
Made to Last
Farm switches endure extreme conditions—vibration, temperature swings, dust, and moisture—so this PTO switch features heavy-duty internal contacts rated for thousands of cycles. The robust construction resists electrical arcing that occurs when engaging high-load implements, and unlike cheaper universal switches, it’s engineered specifically for the electrical demands of modern tractor PTO systems.
Good to Know
Installation requires basic electrical knowledge—disconnect your battery, remove the faulty switch, and install this replacement using existing wiring connections. The mudguard mounting location keeps it within easy reach while protecting it from direct weather exposure. Weather protection sealing rubber is available separately (QTP-55855 or QTP-55857), and this switch works alongside related PTO components like QTP-64642.
