HarvestMotion Plus – 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^TM  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, varies by model) 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 105€ per day of grass harvest and 119€ per day of corn harvest*.

 

*NOTE: Based in internal benchmark data from 2020: JD18X John Deere 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 John Deere 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 JD18X 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 13.5L (824-cu in.) engine.
• Get the same high productivity level on the 9500, 9600 and 9700 SPFH as the Liebherr® V12 engine 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.

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 pressurised oil lubrication.

 

The John Deere Premium KP is available for 9500 through 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.

The following diagram shows the complete John Deere Premium KP offering with all possible combinations.

The following additional options are also available for the Premium KP.

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
• Pressurised 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

All XStream KP options for 9000 series are available with 10- or 11-inch rolls.

 

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.

Overview

Due to increased machine usage (chopping more tons per hour), standard high-quality steel parts need to be replaced more frequently. Since 2010, John Deere has been meeting the challenge and exceeding expectations with Dura Line wear parts.

 

Dura Line components  were developed by John Deere and are installed in high wear spots on the self-propelled forage harvesters (SPFH), mainly in the crop flow. The technology is normally used for heavy-duty environments such as mining and machine tooling. It is the highest material quality in the industry that is installed on an SPFH.

Benefits

• The coating is extremely wear resistant with an extraordinarily smooth surface due to the special heat treatment and a proprietary tungsten carbide composition.
• Dura Line provides a permanent fast-chopping process with low crop friction on the components while fuel consumption remains low.
• Tests show that when chopping in the same crop conditions and chopping the same tonnage, Dura Line parts last four times as long as, or longer than, standard parts. Time and money associated with replacing parts are significantly reduced.
