1250P Research Plot Harvester

Intended Use

The 1250P Research Plot Harvester is used to harvest test plots of corn silage, sorghum, alfalfa, grass, switchgrass, or other forages and/or biomass crops.  The unit can also be used with an NIR sensor to gather moisture, starch content, protein, other constituents, along with weight, sample weight, and location settings on a tablet PC in the cab.  A second seat in the operator station allows for an operator to collect samples in the cab.


Function of Unit

Crop from the harvesting components enters the upper hopper while harvesting.  Once the plot material is weighed, the upper hopper drops the material into the lower portion of the unit.  The operator gathers a sub-sample from an elevator in the cab.  The crop is simultaneously fed into a blower system and delivered through a secondary spout to a wagon or can be spread on the ground.  The system is controlled by the RCI PlotPro Software System.
