Schaffert Mfg.'s Graham 4-Link Force Closing Wheel System offers wireless row level controls and monitoring, including as-applied mapping and statistics, utilizing the Graham Command Pro tablet. Unlike other products that are manual weight setting with no sensor feedback, Graham 4 Link Force offers active, automatic weight management on the closing wheels.

12 volt, 2 inch stroke electric actuators on each row provide up to 125 pounds of down pressure. Graham Torsion Control provides over 100 pounds of stored energy for necessary up-pressure or necessary adjustments through various soil conditions to maintain a smooth ride of the closing wheel. The System can be paired with Graham Force and Graham Pro electric drives to maximize planter performance.
