Brand Name or Equal

The alfalfa/forage project needs a second research plot harvester with enclosed cab to meet the demands of the expanding alfalfa research program. The harvester should be 4-wheel drive, no wider than 48 inches, and include a/c and heat in the cab. It is especially critical that the cutting width be 36 inches with adjustable cutting height on a front header. It will be working in small forage plots of alfalfa requiring close cuts and a small turn radius. Through market research the RCI Engineering 36A Research Plot Harvester is an example of a harvester that meets our requirements. Use the specifications below to provide a brand name or equal plot harvester for the Water Management Research Unit at San Joaquin Valley Agricultural Sciences Center.
