Plot Combine Specifications

Specifications:

BASE: Plot combine * set up for one or two-person operation, hour meter, hydraulic charge pressure, ammeter, fuel gauge and threshing cylinder speed, Exterior lighting, Sample bag storage DRIVE: Hydrostatic traction drive, forward and reverse, Minimum 70 hp water-cooled diesel engine, Oil cooling fan, 25-gallon capacity fuel tank, Electric clutch engagement and Power Steering; Hydraulic failsafe brakes must be equipped with the specified FAIL-SAFE brake, which is a brand name brake system that is hydraulically controlled and takes hydraulic pressure to release the brakes. This is a very important safety feature. If hydraulic pressure is lost or if the engine is shut off, the brakes engage automatically.

THRESHING: All metal, totally ENCLOSED rasp bar type threshing cylinder* Cylinder must be enclosed to prevent contamination between plots, 15" x 31.5" (38 cm x 80 cm) with a minimum eight metal rasp bars for proper threshing; Hydraulically driven threshing cylinder, with variable speed control and tachometer in cab (Variable speed belt drive, not acceptable), Cylinder speed adjustable from 0 to 1150 RPM (i.e. without changing pulleys) and independently engaged from the rest of the combine; NO variable speed sheaves and belt drive CONCAVE: Concave under slung, self-cleaning, quick adjust with lock, with narrow wire spacing for Barley and a concave access panel for quick access for purity applications.

SEPARATION:

Full length conveyor under concave for positive grain movement, one set of upper and lower fixed hole sieves for Barley, straw walker style upper sieve not acceptable, 22 mm upper sieves, 10 mm lower sieve, Air column cleaning system preferred, variable speed winnowing blower, fixed curtains to prevent rebounding of seed.

SEED HANDLING: Fully pneumatic seed delivery with variable-speed cyclone blower, Note* Elevator, paddle or conveyer delivery not acceptable, system must include the ability to route seed to either bagger from the side of the combine or to grain tank for bulk seed, cyclone seed hopper mounted behind driver, with electric opener on cyclone with side sacking chute with platform for side sacking of samples.

GRAIN TANK: Minimum 15-bushel grain tank with gravity spout HEAD: 60” wide Floating cutter bar standard reel header with auger, air cleanout on header for 100% cleanout between plots, 5-bat aluminum pick up reel * Prefer Hume style reel, hydraulic reel height adjustment, hydraulic lift for header, floating snouts pivot-mounted to header, mini Cleat Loc pattern feeding belt, reel Flaps (1 set) for reel, header must be a quick attach style for easy access for maintenance.

MISCELLANEOUS: Heavy duty frame construction for longevity and reliability, hinged safety guards, operational, parts and technical manuals, front and rear lighting, flashers.

Dimensions: Maximum overall weight - 8000Lbs, Maximum overall length -19 ft.

PARTS AVAILABILITY: U.S. ORIGIN COMPONENTS TO ALLOW PURCHASE OF REPAIR PARTS FROM LOCAL VENDORS; prefer the combine uses standard SAE components and specifications including: standard US fractional bearings, belts, sprockets and shafts. This will allow the user to find parts locally and will allow competitive prices for replacement parts from several vendors instead of just the factory. Vendor must provide 24-7 service for repair parts for plot combine. Factory must also be able to provide next day air shipping services to reduce any down time that may happen during the harvesting window DELIVERY AND TRAINING: Final price must include delivery of plot combine with the above specifications to the USDA- Stillwater, OK. with a full In-Field orientation to USDA Researchers prior to 09/30/2021. Orientation to be performed by factory trained personnel.

WARRANTY: Prefer the combine has at least 2 years of warranty and (1) On Site PM Service Research methods:

Field plots are planted at multiple locations each year to measure adaptation of potential germplasm/cultivars to each location. All lines are agronomically evaluated at each location including grain yield calculated from combine harvested plots. Data obtained are critical to selection of lines for release and for publication.
