NEW 7000 SERIES SELF-PROPELLED FORAGE HARVESTER
The John Deere 7000 Series Self-Propelled Forage Harvester roars into the harvesting marketplace with the capabilities to out-chop the competition, valuable features your customers have been asking for, and technology to keep harvesting hour after hour. John Deere introduces the new 7000 Series Self-Propelled Forage Harvester with more horsepower, improved operator comfort, increased productivity, and greater technological enhancements than ever before. Six new models step up to complete the new lineup. Four standard (7200-7500) models offer a power range of 315 horsepower to 570 horsepower. Two wide cutterhead models, the 7700 and 7800, feature wider functional crop-flow components and increased horsepower with either a 570 horsepower or 660 horsepower engine. The wide cutterhead models have limited availability during model year 2003, while the standard models will be in full production during 2003.

Increased Horsepower The John Deere PowerTech Engines have been redesigned to have more horsepower than ever before. Engine enhancements allow higher horsepower without increasing engine displacement. The models deliver torque rises in excess of 19 percent, with the top-end 7800 delivering 660 horsepower at 1900 rpm using a QSX15 liter Cummins engine. Composite Styling The 7000 Series features new sleek composite styling based on customer feedback requesting an updated look. With its modern design, the SPFH has an entirely new look, and the styling itself is also functional. The new styling was engineered with maximum airflow for better cooling and air intake by improving air circulation along the side and rear vents. The composite styling is lightweight, durable, and fade-resistant. The new composite styling of the 7000 Series SPFH offers more than just good looksit provides actual benefits to the customer.
Increased Cooling Capacity The composite styling allows better airflow through the rotary air screen. The rotary air screen is 40 percent larger on the 7000 Series and comes standard with a rotary screen-cleaning brush. In addition to these changes, the 7400, 7500, 7700, and 7800 models feature a cooling fan made of composite material that is over 50% larger than the 50 Series. This fan has a hydraulically engaged clutch. Sensors read the temperature of the cooling air and hydraulically engage the plate-style clutch, providing positive engagement. The ability of the machine to produce to full capacity in high ambient temperatures has been greatly enhanced.
Cab Enhancements The forage harvester cab has been completely redesigned with the forage harvester operator in mind! Now the operator will have the largest cab in the industry with easy-to-use fingertip controls and the space to conduct business as if he was in his office. The spacious forage harvester cab offers greater comfort, decreased noise, spout visibility, and eyelevel controls. The cab enhancements came from customer feedback that requested a cab that would reduce operator fatigue and have an office environment. For comfort, the forage harvester cab provides operators with four more inches of leg room, a wider ComfortCommand seat, ergonomically designed fingertip controls, and the largest windshield in the industry. The operator has the space to sit comfortably in the cab for the 1214 hour day that the business requires. In addition, the cab has a wider training seat, a cup holder, an AC adapter, and a cool box in every cab. Electrically adjustable and defrostable side mirrors and Field Office space (located under the training seat) are available as an option. The new cab design is based on a 50 Series combine, but it was redesigned with full-glass rear corners, laminated glass, and a sound-prevention floor mount. The full-glass rear corners and wider windshield allows the operator to see all the action down on the field and windrow, plus have a birds-eye view of the spout while finishing off trucks and wagons. The 7000 Series cab sound has been decreased by 50 percent compared with the 6050 Series cab, with specially designed laminated glass and a thicker floor mount making the cab quieter than ever before. For the first time ever, customers will sharpen knives, adjust the shearbar and length of cut without leaving their comfortable cab. Plus, the cab is designed for maximum productivity as the kernel processor roll spacing can be adjusted on-the-go and one button adjusts float or header position. In addition, the forage harvester cab brightens the way for field harvesting with an enhanced field lighting system featuring xenon lights and RowFinder side lights. IntelliGuard Metal Detection System Offering the best metal detection system in the industry, the IntelliGuard metal detection system is twice as sensitive and offers more convenience than ever before. The intelligent system provides increased reliability and diagnostics to the operator. The system can be calibrated to allow optimum sensitivity under varying crop and machine conditions. Even if the feedrolls are damaged, the metal detector can be recalibrated to ignore the damage while maintaining the ability to sense metal. If false tripping occurs during rough field conditions, the operator may adjust the sensitivity range to account for the vibration in the field. LED lights indicate the location where the metal tried to enter the machine, so the operator can find the metal quickly. In addition, built-in diagnostics locate trouble spots to decrease downtime.

CAN Bus Electronics The increased electronic capability of the CAN bus electronic system allows the operator to have more machine information, greater diagnostic ability, and increased reliability. The CAN bus system has a new electrical cabinet located next to the cab stairway. The electrical cabinet has been specially designed to resist dust, air, and moisture. Three circuit boards are now located in this central location, and all fuses and relays are together. The circuit boards are designed for fuse and relay parts commonality and have a testing port for easier diagnostics. In the cab, a Service Advisor port and 12-volt powerstrip gives technicians a clean and comfortable place to troubleshoot warning codes. With fewer wires and connectors and greater diagnostic capability, the 7000 Series are designed for decreased downtime and increased productivity.
Infinitely Variable Length-Of-Cut Transmission (IVLOC) The Infinitely Variable Length-Of-Cut (IVLOC) transmission provides the ultimate versatility to meet the desires of the end user. The IVLOC technology provides the operator the flexibility to adjust for each nutritionists ration. The IVLOC transmission is gear-driven and hydraulically controlled. To provide a consistent theoretical length-of-cut, planetary gears drive the feedrolls and are regulated by a hydrostatic motor controlling the speed of the feedrolls. The cutterhead speed remains constant, but the feedroll speed changes as the operator chooses the new length-of-cut.
Using established IVT technology, several in-cab adjustments are now possible: 1) On-the-go LOC adjustments in 1 mm increments 2) Reversing feedrolls without engaging cutterhead 3) Reverse knife sharpening at low engine idle 4) On-the-go kernel processor roll spacing adjustments Cutterhead Configuration 48 knife 40 knife
Theoretical LOC 5 mm to 22 mm (.19-in. -.83-in.) 6 mm to 26 mm (.24-in. - 1-in.)
Curved Chute Design The transition area between the cutterhead and (kernel processor) blower has been redesigned. The 7000 Series machines feature a new curved transition chute that allows crop to follow the contours of the new curved design, virtually eliminating the plugging problems associated with gummy alfalfa. Through the use of high-speed photography and testing, John Deere has been able to optimize performance in all types of crops. Redesigned Kernel Processor Combining with the new curved chute design and redesigned kernel processor (KP), material flow has been optimized and the machines crop capacity has increased, allowing for more tonnage chopped per hour. The kernel processor rolls have been realigned, with the top roll being offset 2-in. from the bottom roll. The change in roll positioning allows for better crop control as it feeds into the aggressive pinch points of the new sawtooth KP rolls, which are standard on the 7000 Series. The top roll now turns 20 percent faster than the bottom roll. The advantage is reduced loading on the RH serpentine drive belt. Due to the inverse roll speeds, there will be less slippage of the serpentine belt and efficiency is greatly improved. A triple belt now drives the KP. Double row bearings have added considerable reliability to the KP. The new bearing features two grease fittings; one greases the double row bearings, the other greases an annular groove between the bearing and seal, which flushes contaminants out. These changes will significantly add longer life to this wear part. Rear Axle Mechanical Hydrostatic Transmission For greater slip and traction control, the 7000 Series SPFH features a mechanical hydrostatic four wheel drive available in a narrow or wide rear axle. The mechanical hydrostatic transmission has a self-engaging 30 percent differential lock and automatically matches the front drive wheel speed for better control. The drive system allows for smoother engagement and greater slip control in backwards uphill conditions. The mechanical drive shaft runs from the hydrostatic motor driving the rear wheels for maximum traction.

Increased Fuel Capacity The 7000 Series offers increased fuel tank capacity, which can lend the customer additional hours in the field before needing to refuel. The 7200 and 7300 SPFH offer an optional fuel tank that holds an additional 106 gallons of fuel. This 291 gallon tank comes standard on the 7400, 7500, 7700, and 7800 Forage Harvesters.
Wide Cutterhead Models The 7700 and 7800 models offer wider functional crop flow areas and higher horsepower, providing optimum capacity in any crop harvested. All functional crop flow components increased in size, including the feedrolls, cutterhead, kernel processor, and blower. By widening the cutterhead 17 percent, the wide cutterhead machines provide customers the largest cutterhead in the industry and increases total machine capacity. The KP roll diameter and width increased for processing the higher through-put capacity of crop flow from the cutterhead to the blower. The blower is now 24% wider and the diameter is 25% larger than the standard model SPFH.

Harvesting Unit Improvements Rotary Harvesting Units The 688 Rotary Harvesting Units now offer lateral tilt frames and water-cooled clutches factory installed. The 686 Rotary Harvesting Units lateral tilt frames increase productivity as the frame pivots to meet the contours of the field and water-cooled clutches help to dissipate heat in heavy corn conditions. It is also possible to order the 684, 686, and 688 Harvesting Units less a mounting frame. This allows the dealer to stock the harvesting unit and add the mounting frame later for the appropriate base SPFHJohn Deere 5000 Series, 6000 Series, 7000 Series, Claas, or New Holland. 2003 Hay Pickup Units Reinforced chains, 25/22 tooth sprocket to increase auger speed, compressor sheet standard, new auger spring, and a 1110 Nm slip clutchall of these enhancements will improve feeding to better match the higher-capacity 7000 Series SPFH. The compressor sheet can be automatically raised by the machine when the feedrolls stop. The base machine must be equipped with single hydraulic valve; manual control can be achieved using the double hydraulic valve. Available: 7200-7500 December 2002 7700-7800 Limited availability
