The John Deere JD18X engine with 18L (1098-cu in.) displacement delivers unmatched performance and characteristics. The unique engine characteristic and efficiency brings the John Deere self-propelled forage harvesters (SPFH) into another performance league in the 700- to 800-PS (690.4- to 789-hp) power class. With the JD18X engine comes unique features and high comfort on the 9500, 9600, and 9700 SPFH models.
Perfect engine characteristic for SPFH application
Diesel only engine – no diesel exhaust fluid (DEF)/AdBlue® with Final Tier 4 (FT4)/ Stage V (EU) emission regulations
HarvestMotion Plus
Long engine oil service interval (750 hours)
The JD18X engine was awarded “Diesel of the Year 2021,” confirming the performance and the Diesel only concept.
The unbeatable performance of the JD18X engine together with the HarvestMotion Plus concept achieves unique power and torque rise in the 700- to 800-PS (690.4- to 789-hp) power class.
The unique engine characteristics with constant, strong power and torque rise at around 1300 rpm provides a highly efficient forage harvester and comfortable driving in every situation.

Efficient, powerful, and reliable HarvestMotion Plus concept
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.
