High-performance self-propelled forage harvesters with the John Deere 9000 series

The new 9000 series self-propelled forage harvesters are available with John Deere's full range of AMS Precision Agriculture systems, for optimal comfort and improved cutting quality.
John Deere is introducing four new models of self-propelled forage harvesters with a power output of 625 to 970 ch.

Equipped with the latest forage harvesting technologies, the 9000 series will enable customers to increase their productivity by 10% while also reducing fuel consumption by 10% compared with the brand's current top-of-the-range machines (at equivalent power). As for corn silage quality, the 9000 series cracks kernels with 10% higher intensity.

These outstanding performance figures have been verified in various field tests carried out by John Deere, as well as by recognized independent research institutes.

The design of these new models has been completely rethought and includes major features such as the dual exhaust. The three largest models, the 9700, the 9800 and the 9900, are equipped with a powerful Liebherr V12 engine of 24,2 l.

This high-performance engine has been designed to be efficient at low rpm. Even below 1 400 tr/min, it delivers incredible torque and handles peak loads superbly.

This capability, combined with several other improvements aimed at increasing efficiency, notably the optimization of the rotation speed of components at low rpm, is the basis of John Deere's new HarvestMotion concept, which considerably increases output and delivers fuel savings unmatched in the industry.

The 850 mm wide feed channel is matched to the machine's impressive output, thereby optimizing forage quality and chopping efficiency. Because of their very high engine power, these new forage harvesters are equipped with a reinforced drivetrain and an improved chassis.

The well-established DuraDrum multi-knife rotor has also been designed to handle enormous harvesting throughputs regardless of the selected cutting length.

John Deere is expanding its range of kernel processors with the introduction of the XStream model. This ultra-high-performance processor was developed in collaboration with the American company Scherer, an experienced leader in the field.

Perfectly suited to the high-performance engine, it provides a roll diameter of 250 mm and a roll speed differential of 50%, thereby increasing cracking intensity by 10%, regardless of the cutting length.

Several kernel processor roll designs are available: sawtooth on the Premium and XStream processors, and XCut on XStream models only. XCut rolls feature a helical groove on the roll surface.

Both roll designs are available with the proven, ultra-resistant Dura Line coating, for greater durability. Rolls for immature grain are available for 2 types of processors, while Milo rolls are available only on the Premium processor.

Another feature of the new XStream kernel processor is the integrated temperature control system and air-pressure oil lubrication (rather than grease) of the bearings, which considerably increases durability.

As on the 8000 series forage harvesters, the kernel processor can be retracted in just five minutes, allowing quick conversion between corn and grass. The new 9000 series self-propelled forage harvesters are available with John Deere's full range of AMS Precision Agriculture systems, for optimal comfort and improved cutting quality.
