Description
When your tractor’s electrical systems start acting up—maybe the PTO won’t engage properly, transmission shifts feel sluggish, or you’re getting intermittent fault codes on the dashboard—it often comes down to a faulty switch assembly. When your PTO won’t engage, transmission acts erratically, or you’re getting electronic fault codes, this control solenoid is often the hidden culprit. This switch assembly keeps your modern tractor’s complex electrical systems talking to each other like they should.

Built for Real Farm Work
This switch assembly fits a wide range of New Holland tractors from the smaller TM and TSA series utility tractors up through the bigger T6 and T7 series row-crop machines. Whether you’re running a loader on a T6.140, pulling implements with a T7.245, or doing hay work with a TM175, these tractors depend on precise electrical control for everything from PTO engagement to transmission operation.
Made to Last
These solenoids are built tough to handle the demands of modern farming—from the heat of summer fieldwork to the cold of winter chores. The electrical contacts are designed to handle thousands of switching cycles without degrading, and the housing protects against dust, moisture, and the corrosive effects of fertilizers and chemicals.
Installation Notes
This is typically a straightforward replacement—disconnect the battery, unplug the old switch, and plug in the new one. Professional installation is recommended to ensure proper electrical connections and safety system integration. Always disconnect battery power before electrical work and verify correct pin assignments using tractor wiring diagrams. Test all functions after installation to make sure everything’s working properly.
