Adjusting Seed Drill Control Sensors
Sowing shaft sensor (A), fan shaft sensor (B) and land wheel sensor (C) require to be correctly adjusted for an accurate monitoring.
Sowing Shaft Sensor
Adjust distance between sensor (A) and magnet (D) as specified. Secure sensor with lock nuts (E).
Specification
Distance Between Sensor and Magnet
-Maximum Distance

Turn sensor (B) into fan shaft support until it contacts a cam and then turn back half a turn. Thus the specified distance is obtained. Check that cams will pass sensor freely. Secure sensor with lock nuts (E).
Land Wheel Sensor
Adjust distance between sensor (C) and rotating bar magnet (D) to specification. The south pole of the bar should then point toward the sensor. Secure sensor with lock nuts (E).
