30A Research Plot Sampler

Intended Use

The 30A Plot Harvester Sampler is used to harvest test plots of corn silage, sorghum, alfalfa, grass, switch grass, or other forages and/or biomass crops.  The unit can be attached to either a John Deere Pull-Type or Self-Propelled Forage Harvester.  The sampler can also be used with an NIR sensor to gather moisture, starch content, protein, other constituents, weight, sample weight, and location settings on a tablet PC in the cab of the power unit.


Function of Unit

Crop from the Forage Harvester enters the diffuser while harvesting.  The diffuser drops the material onto the weighing belt.  The operator gathers a sub-sample from the cross auger and places it on the scale for weighing.  Once weighed, the sub-sample is stored beneath the seat.  The PLC/Control Panel is located to the left of the operator.  A display is provided for the operator to note scale weight but is not directly used by the operator in the normal operation of the unit.
