Hesston WR9800 Windrower

Hesston by Massey Ferguson has unveiled its Tier 4 Final WR98000 Series of self-propelled windrowers.

According to Hesston, two new Tier 4 Final models smooth, consistent cut and uniform, precisely conditioned windrow plus a quiet, comfortable ride.

“These two new machines build upon the industry-leading innovations introduced in 2011, when the WR Series debuted,” says Dean Morrell, product marketing manager for hay and forage. “Operators love the quiet, comfortable cab, the smooth ride of our GlideRider rear-axle suspension system, and the responsive steering from our electro-hydraulic steering control system.”

The WR9800 Series windrowers are powered by AGCO POWER diesel engines, led by the AP66-4F, a 6.6-liter engine in the WR9870. This model offers 225 horsepower to operate in heavy crop conditions like winter forage, wet silage hay, and hilly or rough terrain.

The WR9860 is powered by a 4.9L four-cylinder QuadBoost engine that boasts 195 horsepower. This additional power provides a higher cutting speed of 17 mph, plus a maximum road speed of 22 mph for quicker moves between fields.

A redesigned control handle is a significant addition to the WR9800 Series. Hesston says the handle has a more ergonomic shape that easily fits the operator’s hand. As well, it is outfitted with nine user-configured, programmable control buttons and two standard buttons, putting all machine and header functions in one location. Operators can set the machine’s control functions to their own needs and preferences, including new control features such as load control and power shift.

Additional conveniences for the operator include a larger platform, for easier entry into the cab and more room to stand on when fueling the machine. A new step for the ladder offers more windrow clearance, and a new location for the air filter provides stand-up servicing and more room to do so. Finally, the oil tank gauge, DEF tank and toolbox have been moved to what Hesston calls more convenient locations.

“When Hesston introduced the WR9700 Series, it was the first manufacturer in the industry to develop a machine that operates all hydraulic, engine and drive functions via an onboard computer terminal,” says Morrell. “We’re very proud that the WR windrowers have seen such success in allowing hay producers to develop quality hay faster and more efficiently with an enhanced level of precision.”
