The Powershift transmission includes a power management setting for pulling large implements. When engaged, it automatically downshifts or upshifts depending on the load, providing the maximum horsepower and torque required for the situation. A constant ground speed setting is available for light duty applications, selecting various engine RPMs to maximize fuel efficiency.
A key feature of the tractors is the patented undercarriage with the Mobil-trac system, which uses oscillating mid-wheels, leaving a lighter footprint and reducing compaction while improving ride comfort.
"The oscillating mid-wheels are attached to a walking action axle. They will pivot up and down as we go across the ground," Bergin explains. This gives the track the ability to mold to the ground, walking across it rather than falling over bumps and other obstacles.
"If we're maintaining constant contact across the ground, we're reducing our compaction," he adds.
The MT700E and MT800E Series use a hydraulic cylinder to put pressure to the undercarriage, improving driver-to-belt contact and traction. The cylinder absorbs shock and will smooth the ride out after hitting an obstacle. Hydraulic pressure is displayed on the monitor in the cab, and the operator can increase or decrease tension according to their needs.
The undercarriage includes two Marsh Mellow springs. "It's basically a big fabric rubber spring that will never, ever wear out," Alt explains. Bergin adds the springs attach the undercarriage to the frame of the machine.
"Those springs are going to pivot up and down, so that's going to really help absorb the amount of vibration and shock we experience as we go across the field," Bergin says. "It's allowing those tracks to pivot up and down to ensure we're making constant ground contact."
Rather than using tracks as an aftermarket product, the MT700E and MT800E Series are built from the ground up specifically for this track system, improving balance and ballasting – the ability to add weight to compensate for a load.
"Their balance is 50/50 from front to rear," Bergin says. "So that makes it very easy for us to add or subtract weight if need be when we add an implement to the rear of the machine."
It also improves the ride and allows the engine to be mounted lower. "Our tractor has a lower center of gravity for better balance, better design, but also it allows for that in-line design."
