Combine head position sensors monitor header height, tilt, and float position — feeding real-time data to your combine's control system to maintain consistent cutting height and protect the header from ground contact. A failed or drifting position sensor causes erratic header behavior, inconsistent cutting depth, and can lead to costly header damage if the automatic height control stops responding correctly.
We stock head position sensors for the most popular combine platforms, with OEM cross-reference numbers on every listing so you can identify the right part for your machine quickly and get back in the field.
Symptoms of a Failing Position Sensor
- Header hunting or drifting at a set cutting height
- Auto header height control not responding or behaving erratically
- Fault codes related to header position or height control on the display
- Header dropping or raising unexpectedly during operation
Compatible Platforms
Sensors available for John Deere, Case IH, and other major combine platforms — with OEM part number cross-reference on every listing for accurate identification.
Pre-Season Check
Test your header height control system before the first field. If you're seeing erratic behavior or fault codes, diagnose the sensor now — not when you're trying to make the most of a narrow harvest window.
