Abstract

A tractor-assisted multi-row harvester for root vegetables includes adjacent pairs of a lifting share and a picker and a pair of traction assemblies, for example in the form of endless track assemblies, one of which being behind and registered with at least one of the adjacent pairs of a lifting share and picker and being motorized and energized so as to compensate at least partially for pressure on the lifting shares. The harvester includes sensors on the motorized traction assembly and/or on the lifting shares that generates signal(s) indicative of the pressure on the lifting shares and that is used to control the motorized traction assembly to compensate for the pressure.
