Built for Real Farm Work
Your Case BD series tractors—whether it’s a compact D212 for chores or a larger D440 for fieldwork—depend on reliable electrical systems to get the job done. These utility tractors handle everything from loader work and mowing to light tillage and hay operations. The 7-pin design means each electrical circuit gets its own connection, preventing the voltage drops and overloaded wires that can cause starting headaches.
Made to Last
Farm equipment takes a beating, and ignition switches are no exception. This replacement is built with quality copper contacts that won’t wear out like cheaper automotive switches. The housing handles the constant vibration from field work and the temperature extremes your tractor faces season after season.
Installation Notes
Swapping this switch is straightforward—disconnect your battery first to avoid sparks, then it’s just a matter of matching up the wire connections. Take a quick photo of your old switch wiring before removal to save yourself time later. The 7-pin setup is critical, so don’t try to make a different pin count work.
