Three New Forage Harvesters Have Been Added To John Deere's 9000 Series

Deere's Forage Harvesters are Powered by a New Engine

John Deere has added three new self-propelled forage harvesters to its lineup, one of which is brand new.

"To improve performance, John Deere expanded the horsepower offerings for our wide-body forage harvesters, which include the 9500 to 9900 models, and made updates to maximize machine uptime and reduce the cost of operation," says Chase Milem, marketing manager for John Deere.

The new forage harvesters begin with the 9500, which Milem claims are completely new and have a maximum horsepower of 755. The company also offers an upgraded 9600 with a maximum of 755 hp and a 9700 with a maximum of 813 hp.

The three machines are powered by a new John Deere JD18X 18-liter engine, which the company claims is 13% more efficient than the previous engine used in these models, owing in part to the fact that it is diesel only and does not require diesel exhaust fluid.

The new engine has a 750-hour service interval, which is 33% longer than the previous 13.5-liter engine. Furthermore, because no DEF fluid is required, the company claims that ownership costs are kept low while machine reliability is increased.

In its 9000 Series line, the company also offers the 9800 (855 max hp) and 9900 (956 max hp) with a Liebherr 24L engine.

The company's HarvestMotion Plus technology, which Milem describes as providing a unique low-rise torque curve that can provide extra power at lower RPMs, is also a feature of the new engine.

"That will allow for an increase in horsepower when they are moving through difficult conditions," he says. "Total throughput is another requirement, to keep pushing the crop forward with increased horsepower."

The 9000 Series forage harvesters also have a new spout that improves operator visibility while unloading. Customers can run in "sticky" crop conditions for longer periods without plugging, according to the company, with additional clean-outs and a change in spout geometry.

The 9000 Series also includes fully integrated AutoTrac RowSense guidance, Active Fill Control with rear unloading, and a new Generation 4 cab display. "These are industry-leading features that are available as factory options," Milem explains.

Another option is the John Deere HarvestLab 3000, which provides constituent sensing and documentation on the fly.

"It can be used as a manure-sensing tool as well as a stand-alone stationary test unit capable of analyzing up to seven constituents," Milem explains. "Among these ingredients are NDF, crude protein, moisture, sugar, starch, crude fiber, ash, and ADF." Farmers can quickly analyze data from worked fields, adjust fertilizer use, select optimal varieties for the upcoming season, and improve water management using the documented information."

Each model is now for sale, with prices beginning at $673,000 for the 9500 Series. Visit for more information.
