Grimme brings extra high-tech to potato lifters

Grimme-air-powerGerman potato equipment Grimme has upgraded its 2-row trailed and self-propelled machines for the 2015 lifting season. The most interesting item is its pneumatic clod and stone separator, called AirSep, and an active swaying stability control for improved digging performance called ComfortDrive. AirSep is unusual in being able to separate stones, wet clods and haulm from potatoes by airflow. It has already been successfully tested on the SV260 and the SE260 Off-set trailed harvesters. The ComfortDrive system, meanwhile, has been designed mainly to reduce sway in offset trailed and self-propelled harvesters fitted with large wheels. Swaying can reduce digging output, says the company, and can be uncomfortable for the pickers. More
