2025 John Deere 9900

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:

1. 10 percent more throughput (t/kW)*
2. 10 percent better fuel economy (L/t)*
3. More hours in the field with 1500-L (396.25-gal.) diesel tank and 90-L (23.8-gal.) urea tank

Improve silage quality with two kernel processing options

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)
• Dura Line sawtooth (178/178 teeth)

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) – available in 25.4- or 27.9-cm (10- or 11-in.) rolls
• Dura Line sawtooth or XCut (120/160 teeth) – 27.9-cm (11-in.) rolls
• Dura Line sawtooth (160/160 teeth) – 27.9-cm (11-in.) rolls
• Dura Line sawtooth advanced (145/165 teeth) – 25.4-cm (10-in.) rolls

Dura Line™ wear parts

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.

Dura Line guarantee

The Dura Line guarantee provides a specified number of engine hours or time of usage (whichever comes first) for the different Dura Line liners. The Dura Line guarantee was first introduced in 2017 and is valid for all 8000 and 9000 Series SPFH models. Dura Line liners damaged from foreign material or misuse are excluded. Only parts that are completely worn are replaced.

For more information about the Dura Line guarantee, contact the local sales organization.

Dura Line packages

The John Deere Dura Line crop flow liners come in three packages. Depending on the individual harvesting requirements, there is a perfect package for every need.

• Basic: Perfect solution for machines mainly harvesting corn
• Premium: Ideal for abrasive conditions (particularly grass)
• Ultimate: Perfect choice for toughest conditions, providing full crop flow coverage

High forage quality with HarvestLab™ 3000 and AutoLoc™ system

The HarvestLab 3000 sensor mounts to the top of the discharge spout and takes accurate dry matter and ingredient readings (more than 4000 measurements per second) of the crop through the sapphire glass lens as crop passes through the spout. This is the same technology forage labs use to measure dry matter. HarvestLab 3000 with John Deere Constituent Sensing measures dry matter and constituents like sugar, starch, acid detergent fiber (ADF), neutral detergent fiber (NDF), crude fiber, crude ash, crude protein, crude fat, Metabolic Energy and ELOS depending on the crop. In addition, the HarvestLab 3000 sensor can also be used as a stationary unit.

Crop type and constituent sensing

When HarvestLab 3000 is used in conjunction with Harvest Monitor™ system, a wealth of important information becomes available to the operator, including productivity in acres per hour, throughput in tons per hour, total area harvested, total crop mass harvested, yields, and dry matter. To measure and document the constituents, a G5Plus Universal Display is required. All data documented on the G5Plus Universal Display is shown in John Deere Operations Center.

When the HarvestLab 3000 is used in conjunction with an 8000 or 9000 Series Self-Propelled Forage Harvester (SPFH) and a GreenStar™ display, AutoLoc functionality is automatically present. AutoLoc automatically varies the length of cut according to the desired crop-dry matter correlation settings based on the dry matter readings from the HarvestLab 3000 sensor. With the AutoLoc adjustment, bunk density is improved and a high forage quality is reached.

AutoLoc - Automatic length of cut

1. HarvestLab 3000 — moisture and ingredients on the go
2. Manual control (operator)
3. AutoLoc — automatic control
4. IVLOC™ transmission — length of control changes on the go

AutoLoc, a feature exclusive to John Deere and unique to the market, brings added value to the HarvestLab sensor and John Deere SPFH. AutoLoc works in conjunction with the HarvestLab 3000 sensor and IVLOC transmission to automatically adjust the length of cut (LOC) based on crop moisture levels to improve bunk density and reduce long particles in dry corn. Nutritionists, herdsmen, and SPFH operators will all benefit from this innovation.

John Deere is leading the industry in providing real-time information that matters most to forage production. Quality forage comes from properly packed silage, which is directly related to the moisture content and LOC of the crop.

LOC changes are made automatically in the field based on moisture readings and predetermined settings determined by operator requirements. No in-field calibration is required to load the LOC requirements; the operator simply uses the GreenStar™ display to program the desired LOC settings at different moisture levels.

When moisture levels of crop in the field change, the IVLOC drive automatically responds to either increase or decrease the feedroll speed, which in turn changes the LOC. If moisture levels of the crop are outside of the desired range, the IVLOC transmission adjusts and limits the LOC based on the maximum and minimum LOC settings as determined by the operator.
