Continues to improve on the performance and serviceability of the popular 9800P harvester, while still effectively harvesting the heaviest pecan and walnut windrows. Refreshed pumps, motors and hydraulic tank, coupled by a new hydraulic circuit drive the improvements. Active cooling boosts the bank-out option cart flexibility. These innovations lead to improved efficiency and improved thermal performance that let the machine do more to bring in your harvest. The effective intermediate dirt chain is carried forward, dropping dirt through the chain before the proven vacuum system pulls debris from the crop, delivering less dust and a cleaner harvest. Extra-large rear balloon tires provide maximum flotation for reduced compaction. Serviceability is improved by a vacuum housing and tunnel designed for easier access and simpler replacement.
