A state-of-the-art engine with ideal performance characteristics and low specific fuel consumption perfectly aligns and synchronizes with a superior crop flow. This is the John Deere HarvestMotion Plus concept. The “Plus” stands for unique torque rise and more power at low engine rpm – an experience of pure performance and efficiency without any compromise. Additionally, there is no diesel exhaust fluid (DEF) required.

The HarvestMotion Plus advantage:

• 13 percent less fluid consumption (diesel plus DEF)
• 48 kW (64.4 hp) of extra power at low engine rpm to easily digest peak loads
• Simple is strong – reliable harvest capacity

LEADING EFFICIENCY

With a maximum engine speed of 1800 rpm, the engine is always operated in its sweet spot. Lower rpm means lower specific fuel consumption. Less fuel consumption means less costs and, in the end, more money in your pocket. HarvestMotion enables up to 13 percent less total fluid consumption, which equals up to $125 per day of grass harvest and $141 per day of corn harvest.*

*NOTE: Based in internal benchmark data from 2020: JD18X engine with HarvestMotion Plus versus replaced model with 4 percent less diesel, no DEF (AdBlue®), and 10 hours of chopping per day.

POWERFUL HEARTBEAT

Less engine rpm, more power, and a unique torque rise – this is what HarvestMotion Plus delivers. The JD18X engine has been tailored to the needs of an agricultural harvesting machine. Operators will feel its strength, and owners will profit off its harvesting capacity. The 18L (1098-cu in.) John Deere engine in the 9000 Series Self-Propelled Forage Harvester (SPFH) with the HarvestMotion Plus concept is a winning combination.

• The 9500 SPFH delivers 23 percent more throughput than the previous 9600 SPFH with a 13.5L (824-cu in.) engine.
• Get the same high productivity level on the 9500 and 9600 SPFH as the Liebherr® V12 provides on the other 9000 Series models (throughput/installed engine power).

RELIABILITY THROUGH SIMPLICITY

Reliable power delivered by modern robust engine technology ensures harvesting capacity. The JD18X engine delivers exceptional performance without needing a complex aftertreatment system. This means unique simplicity in this power class.

LEADING HEADER TECHNOLOGY

John Deere rotary harvesting units are built for reliable and powerful feeding of high-capacity forage harvesters. Two fundamental designs are available to match all producer needs. The 600plus Series Headers are the universal solution for different crops up to 4-m (13.1-ft) tall. The 700plus Series Headers are the perfect solution for high-yielding crops.

Available beginning in model year 2019, the top-model 772 12-Row Large-Drum Rotary Harvesting Unit has been designed to fully leverage the capacity of 9000 Series Self-Propelled Forage Harvesters (SPFH).

The 6X9 Series Pickups with the patented endless flight vortex auger design and optional dual header drive enable high-capacity feeding of John Deere SPFH. Key advantages are the throughput boost in high-yielding crops but also the easy handling of uneven windrows.

VARIABLE HEADER DRIVE

John Deere SPFH come with variable header drive in base. The header speed is automatically synchronized with the feeding speed and length of chop through a hydrostatic IVT™ drive system. This ensures a gentle and even crop transfer from the header into the machine without blocking or disrupting material transition. Producers receive the benefit of high chopping quality and full leverage of the header and crop flow potential.

DUAL HEADER DRIVE

Dual header drive for the SPFH and the 6X9 Series Pickups complements the benefits of the variable header drive. While the variable header drive automatically synchronizes the pickup auger and harvester feeding speed, the dual header drive with its individual hydraulic drive of the pickup tines is speed matched with vehicle speed to ensure clean crop picking in changing conditions and windows.

Tines speed up and slow down with forward speed while the pickup auger speed is still synchronized with the length of chop and feedroll speed. Producers benefit from a better quality of chop, smoother feeding, and an easy-to-utilize harvesting system.

HYDRAULIC FEEDROLL DAMPENING

The 9000 Series SPFH offer the hydraulic feedroll dampener in base. Next to the four individual springs applying high pressure on the crop mat entering the machine, the dampener supports crop compaction in uneven crop conditions and ensures smooth feeding even at the highest feeding speeds when chopping for a very long period.

UNIQUE FOREIGN OBJECT PROTECTION

A state-of-the-art metal detector scans for metal in the crop mat and stops the intake in case of tripping. Optionally, this safety device can be completed with a unique stone detection feature that senses for knocks and abnormal feedroll movement. Two redundant sensors developed for this application improve solid foreign object detection and minimize false tripping caused by lumps or uneven windrows.

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.

The SPFH feature the AutoLube central greasing harness; the respective central greasing equipment is available on the Premium KP kernel processor. The XStream KP kernel processor features automatic pressurized oil lubrication.

The John Deere Premium KP is available for the 9500 to 9800 models, and the John Deere XStream KP is available for all 9000 Series models. The 9900 model can only be equipped with an XStream KP.

JOHN DEERE PREMIUM KP

On the 9000 Series, the proven John Deere Premium KP can be installed on the 9500 through 9800 models. With their highly intense processing, they deliver excellent forage quality at any length of cut.

The main features of the Premium KP are:

• 240-mm (9.45-in.) roll diameter for different crops (maize and whole crop)
• 32 percent speed differential; option of 40 percent speed differential
• Standard KP housing with grease lubrication in base
• Electric KP gap adjustment from the cab as option

The following rolls are available for the Premium KP:

• Standard sawtooth (118/118 teeth)
• Dura Line™ sawtooth (118/118 teeth)
• Whole crop sawtooth (178/178 teeth)

With the option of Dura Line rolls, a longer lifetime and less wear can be reached, resulting in lower cost of operation.

For easy and uncomplicated mounting and dismounting of the KP, a crane with electric winch can be installed as an option.

JOHN DEERE XSTREAM KP

The John Deere XStream KP is the heavy-duty solution made for high throughput and high-horsepower machines and stands for extreme processing at any length of cut in any crop and any conditions.

The XStream KP rolls are manufactured and delivered by Scherer Inc., located in South Dakota, United States. The kernel processor is supplied ex-factory by Scherer Inc. and fits on all 9000 Series models. As Scherer Inc. has a strong focus on dairy forage production and is the leading company in KP roll designs and manufacturing since 1999, a strong statement is set regarding kernel processing and forage quality.

More information about Scherer Inc. can be found on their website: http://www.schererinc.com/

The main features of the XStream KP are:

• 250-mm (9.8-in.) roll diameter
• 50 percent speed differential
• Heavy-duty housing with KP roll quick-exchange system
• Pressurized oil lubrication of bearings
• Bearing temperature monitoring system (option)

The following rolls are available for the XStream KP:

• Dura Line sawtooth (110/145 teeth)
• Dura Line XCut (110/145 teeth)
• Dura Line Whole Crop XCut (145/165 teeth) – only available for 9000 Series

In comparison to the Dura Line sawtooth rolls, the Dura Line XCut rolls have a spiral groove sawtooth profile that delivers excellent processing, especially at long lengths of cut. The spiral groove design delivers highly processed plants and smashed kernels.

For easy and uncomplicated mounting and dismounting of the KP, a crane with electric winch can be installed as an option.
