2025 John Deere 9000 Series 9800

2025 John Deere 9000 Series 9800

• 856 hp, 24L Liebherr V12 engine

• Driveline designed to deliver optimal crop flow when the engine is operating in its efficiency sweet spot

• The ProStream crop flow designed with extra heavy-duty components for high horsepower and more throughput than ever before

Features may include:

• Low engine speed concept

• The John Deere 9000 Series Self-Propelled Forage Harvesters (SPFH) have been developed with a clear focus on machine performance: more throughput and less fuel consumption while providing maximum uptime and low cost of operation.

• A key success factor is the concept of lower engine rpm at higher harvesting component speeds.

• V12 – 24-L concept: The Liebherr® D9512 engine

• The top-model 9700, 9800, and 9900 SPFH are equipped with a Liebherr 12-cylinder V-engine with 24-L displacement. The Liebherr D9512 is a state-of-the-art engine and delivers what a high-performance forage harvester requires:

• High power density and great fuel efficiency

• Constant maximum power down to lower engine rpm

• Torque curve designed for forage harvesting applications

• The broad maximum power range of the Liebherr V12 engine cuts off the less-efficient rpm area above 1800 rpm. The rising torque curve down to 1300 rpm enables efficient operation of the machine in the lower rpm range.

• Revised driveline with optimized component speeds

• To reach maximum efficiency and performance, all machine component speeds are re-worked and laid out for best function in the 1400 to 1800 engine rpm range. This also leads to better fuel efficiency with an optimum range from 1250 to 1600 rpm, where the engine has its lowest specific fuel consumption (g/kWh).

• This unique concept delivers undisputed customer value:

• 10 percent more throughput (t/kW)

• 10 percent better fuel economy (L/t)

• More hours in the field with 1500-L (396.25-gal.) diesel tank and 90-L (23.8-gal.) urea tank

• Overview

• John Deere self-propelled forage harvesters (SPFH) set new standards in kernel processing performance. Proven in independent tests during corn harvest in 2016 and 2017, John Deere kernel processors (KP) deliver smashed kernels and highly processed plants that growers expect. With two different models, the John Deere Premium KP™ kernel processor and the John Deere XStream KP™ kernel processor, all different needs will be satisfied.

• Additional details

• All John Deere SPFH can be operated with or without a kernel processing unit in position. When not in use, a crop transition chute (or grass chute) swings into position with a few turns of a crank. The crop transition chute comes standard on all harvesters.
