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.

A tractor-assisted multi-row harvester for root vegetables comprising:
- a frame having a height and first and second lateral sides defining a width of the frame;
- the frame further defining a first axis along its width and a second axis along its height;
- the second axis being perpendicular to the first axis;
- first and second parallel traction assemblies that are mounted to the frame thereunder for supporting the frame so as to be both operatively oriented perpendicular to both the first and second axes;
- the first and second traction assemblies being registered with respectively first and second positions along the first axis near the first and second lateral sides of the frame respectively;
- the first traction assembly being motorized by a motor mounted thereto;
- a three-point hitch mounting assembly secured to the frame for operatively attaching the multi-row harvester to a tractor;
- a plurality of generally parallel pickers that are pivotally mounted to the frame on a first lateral side of the three-point hitch mounting assembly along the first axis so that at least one of the plurality of generally parallel pickers is at least partially registered with the first traction assembly;
- the plurality of generally parallel pickers being slanted relative to the second axis;
- a plurality of lifting shares mounted to the frame, each under and behind a respective one of the plurality of generally parallel pickers for solidary pivotal movement therewith;
- and
- at least one sensor mounted to the frame and coupled to the first traction assembly for generating at least one first signal indicative of a pressure on the plurality of lifting shares;
- the first traction assembly being energized according to the at least one first signal to match the pressure on the plurality of lifting shares.
A tractor-assisted two-row harvester for root vegetables comprising:
- a frame having a height and first and second lateral sides defining a width of the frame;
- the frame further defining a first axis along its width and a second axis along its height;
- the second axis being perpendicular to the first axis;
- first and second parallel traction assemblies that are mounted to the frame thereunder for supporting the frame so as to be both operatively oriented perpendicular to both the first and second axes;
- the first and second traction assemblies being registered with respectively first and second positions along the first axis near the first and second lateral sides of the frame respectively;
- the first traction assembly being motorized by a motor mounted thereto;
- a three-point hitch mounting assembly secured to the frame for operatively attaching the two-row harvester to a tractor;
- first and second generally parallel pickers that are pivotally mounted to the frame on a first lateral side of the three-point hitch mounting assembly along the first axis;
- the first and second generally parallel pickers being on respective lateral sides of the first traction assembly;
- the first and second pickers being slanted relative to the second axis;
- first and second lifting shares mounted to the frame, each under and behind a respective one of the first and second pickers for solidary pivotal movement therewith;
- and
- at least one sensor mounted to the frame and coupled to the first traction assembly for generating at least one signal indicative of a pressure on the first and second lifting shares;
- the first traction assembly being energized according to the at least one signal so as to match the pressure on the first and second lifting shares.
