The Massey Ferguson ignition switch, with its key, switches on the power and then starts the tractor. When the key turns freely, the power cuts out while driving or the starter no longer responds, the switch is often the cause.<\/p>\n\n\n\n

Compatible models:<\/strong> Massey Ferguson 440 Xtra.<\/p>\n\n\n\n

Specifications:<\/strong> key switch, metal body and terminals at the back, supplied with its keys.<\/p>\n\n\n\n

OEM part number:<\/strong> 10300\/502. The key alone is also available under the same part number.<\/p>\n\n\n\n

Part designed from the original and sold under the Valmy France brand. Send us a photo of the back of the old switch: we check the connections before shipping.<\/p>\n\n\n\n\n\n\n\n

The ignition switch wears with every start. When it starts cutting out or sticking, better to replace it before it leaves the tractor at a standstill.<\/p>\n\n\n\n

Identifying your Massey Ferguson ignition switch<\/h3>\n\n\n\n

This switch fits the Massey Ferguson 440 Xtra. Compare the metal body, the mounting thread and the number of terminals at the back of the old switch. If in doubt, send us a photo of the back of the switch from the contact page<\/a>: we check before shipping.<\/p>\n\n\n\n

Replacing it without wiring mistakes<\/h3>\n\n\n\n

First disconnect the battery. Then photograph the wires before removing them, and reconnect each one to the same terminal on the new switch. Tighten the mounting nut without forcing, reconnect the battery and test the power-on, then the start.<\/p>\n\n\n\n

Why choose Valmy France<\/h3>\n\n\n\n

Our switch is designed from the original part and supplied with its keys. A spare ignition key<\/a> is also available on its own. See our Massey Ferguson switches<\/a> and all our tractor electrical parts<\/a>.<\/p>\n\n\n\n

Ordering your ignition switch<\/h3>\n\n\n\n
