Reichhardt Tactile Row Guidance is steering by the aid of a flexible tactile sensor.  The durable synthetic sensor guides from the corn or cotton plant to control the vehicle independent of GPS. The combine or self-propelled sprayer follows the rows regardless of planting conditions.  Tactile row guidance enables the operator to monitor the machine for higher performance and can help reduce operator fatigue. PSR TAC works in 20", 22" and 30" rows.
