The precise plough adjustment is an important factor to minimise material wear and reduce fuel consumption. This is why LEMKEN has developed its unique Optiquick adjustment system. Optiquick allows for easy and efficient adjustment of front furrow width, and tractor/plough pull line, independently of each other. Time and money are saved as a result.
