Starter and Heat Switch with Key for Massey Ferguson TO35, 35, 50, 65, 85, 88, 90 Series Tractors

Description

There’s nothing like turning the key on a cold morning and having your diesel tractor fire right up. But when your starter switch starts acting up—maybe it’s getting hard to turn, contacts are getting corroded, or that heat position isn’t working like it should—cold starts become a real headache. This replacement starter and heat switch gives your glow plugs time to warm up those combustion chambers before cranking, so you can count on reliable starts even when the temperature drops.

What You’re Getting

• Heavy-duty internal contacts that won’t pit or burn like cheaper switches
• Proper heat position for diesel glow plug operation—no more ether or extended cranking
• Slide-on terminals make wiring connections straightforward
• Comes with key so you’re ready to go right out of the box
• Built specifically for the four-terminal setup on these classic Massey Ferguson tractors

Built for Classic Farm Work

This switch fits the workhorse Massey Ferguson models that built their reputation—TO35, MF35, MF50, MF65, MF85, MF88, and MF90 tractors, plus the 35, 203, and 205 industrial units. These are the tractors that handled everything from cultivating and hay making to loader work and general farm chores for decades. Whether you’re keeping a family tractor running or maintaining equipment for a working farm, reliable starting is essential.

Made to Last

Ignition switches live a hard life—constantly twisted by work gloves, exposed to dust and moisture, and expected to carry heavy starter current day after day. This replacement is built with the same quality standards as the original equipment, using robust construction that handles the electrical loads and environmental challenges of farm use.

Installation Notes

Swapping an ignition switch is usually a 30-minute job that solves a lot of electrical gremlins. First, disconnect your battery—you’ll be working with unfused wires. Label or photograph your old wires before removing them; typical connections are Battery (B), Ignition (I or IG), Starter (S or ST), and Heat/Glow (H or G). The product description mentions checking your terminals before ordering—some models used a different switch with different terminal arrangements, so make sure you’ve got the four slide-on terminals this switch is designed for.
