Description
When you’re noticing erratic speed readings on your display or your implements aren’t responding right to speed changes, a failed speed sensor is often the culprit. This magnetic sensor is what tells your tractor’s computer exactly how fast things are spinning, whether it’s for PTO-driven equipment, ground speed monitoring, or transmission control. Without accurate speed data, your precision farming features and implement protection systems can’t do their job.
What You’re Getting
- Precision magnetic sensor provides accurate speed readings to your tractor’s computer system
- Heavy-duty construction built to handle the vibration, dirt, and temperature swings of farm work
- Direct replacement design—no modifications or adapters needed for installation
- Critical component for automated systems like implement protection and precision application rates
Built for Real Farm Work
This sensor works with John Deere 6620 from the 6020 series, 7720 from the 7020 series, and 9600 from the 9000 series tractors. Whether you’re running PTO equipment like balers and mowers, using precision planting systems, or operating large combines, this sensor enables features like automatic PTO management, implement protection, and precision application rates.
Made to Last
Located near critical rotating components, these sensors endure extreme conditions – oil mist, dirt, vibration, and temperature swings. This replacement uses automotive-grade sealing and materials to survive where others fail, maintaining accurate readings season after season.
Good to Know
Installation typically takes 30-45 minutes and requires proper positioning relative to the tone ring for accurate readings. Disconnect the battery before starting to prevent electrical damage. Clean the mounting area and electrical connector thoroughly before installation. After installation, verify operation through your display – you should see steady readings that match your other gauges.
