The site of the 2013 Farm Progress Show in Decatur, Ill., was full of exhibitors showcasing newly launched machinery, technology, and other products. The AGCO lot was no exception, with nine new products, including the MT700E Series track tractors – the MT755E at 350 horsepower, MT765E at 375 horsepower, and MT775E at 400 horsepower. The new MT800E Series, what AGCO refers to as the "beast," includes the MT845E at 450 horsepower, MT855E at 490 horsepower, MT865E at 540 horsepower and MT875E at 590 horsepower.
Both series come with new AGCO Power Tier 4 Final engines. The MT700E Series uses 9.8 liter engines, while the MT800E Series uses 16.8 liter engines. Both achieve Tier 4 Final emissions without using a heat-generating diesel particulate filter. They use a combination of selective catalytic reduction, or SCR, and external-cooled exhausted gas recirculation, or cEGR.
"Having a vast majority of SCR and a small amount of cEGR will reduce not only fuel consumption but diesel exhaust fluid consumption as well," says Conor Bergin, product marketing manager for High Horsepower Tractors.
The engines put out more torque and sustain torque for a longer period of time.
"I'm not going to have to shift the tractor down, I'm not going to have to slow the tractor down, and I'm not going to have to lift the tool I'm hauling up because I'm going have the torque to work through those situations," Bergin explains. "The operator is ultimately getting more work done in the day. We can actually run the tractor at lower engine RPMs, which in turn means more fuel savings."
The engine is mounted to the Caterpillar Powershift transmission, which sends power directly to the final drive without a drop box, reducing parasitics and improving fuel consumption. This contributes to the in-line design.
"Our engine mounts directly to the transmission and then to the final drive and ultimately to the track system," Bergin says. "All the torque we're creating inside the engine is going through the transmission and going out to the final drives."
This transmission provides a smoother shift, says Ash Alt, field marketing manager for High Horsepower Tractors. "If you have to downshift for some reason, it's not going to jerk you out of the seat," Alt says. "It's a faster shift, so it's less power loss."
