Description
When your GPS guidance starts drifting or your variable rate controller seems to be guessing at application rates, chances are your wheel speed sensor has called it quits. This little component is what tells all your precision farming systems exactly how fast you’re moving across the field – and when it goes bad, everything from auto-steer to section control starts acting up. A bad sensor means you might be over-applying expensive inputs in soft spots while missing coverage in other areas.
What You’re Getting
- High-precision sensor that provides accurate wheel rotation data your systems depend on
- Essential component for GPS guidance, auto-steer, and variable rate application control
- Weather-sealed design that handles the dust, mud, and moisture of field conditions
- Direct replacement that restores reliable speed monitoring without modifications
- Quality construction that matches OEM specifications for long-term reliability
Built for Real Farm Work
This sensor works with John Deere 7600, 7700, 7610, 7810, and 8100-8400 series tractors – the big machines you rely on for everything from heavy tillage to precision planting. Whether you’re running a 7810 with a 40-foot cultivator or an 8400 pulling a 16-row planter, this sensor feeds critical data to all the electronic systems that make modern farming possible.
Made to Last
Farm equipment sensors take a beating from road grime, field dust, and temperature swings. This wheel speed sensor is built to handle it all with sealed electronics that resist moisture and contamination. The precision components maintain accuracy from cold spring startups through hot summer field work.
Installation Notes
The sensor mounts at the wheel hub and must be positioned correctly relative to the tone ring for accurate readings. Clean all mounting surfaces and electrical connections thoroughly since corrosion causes erratic readings. Getting the sensor gap right is critical – too close risks damage from debris, too far gives weak signals. After installation, calibrate the system by driving a known distance to ensure your displays show accurate ground speed.
