For customers who prefer stepless transmissions for infinite speed control and ease of drivability, the new EVT will be available for all 410-horsepower 8 Series Tractors including 8R, 8RT, and 8RX models.

“An EVT has electric motors in place of the hydrostatic motors that improve transmission performance, reliability, and increased efficiency. The EVT brings everything customers appreciate from an Infinitely Variable Transmission (IVT), into higher horsepower 8 Series Tractors. Inherently, the electrical components of an EVT are extremely reliable, offer tremendous longevity, and provide better overall tractor control, along with a system built for easy serviceability and diagnostics. In addition, customers will notice an EVT operates more quietly than an IVT.”

said Ryan Jardon, marketing manager for John Deere.

As farmers look to the future, the EVT will likely be the transmission of choice for customers going forward according to Jardon.

“In the future, EVT-equipped 8 Series Tractors, will optionally feature electric power generation capacity of offboarding electricity to power implements. This EVT is the industry’s only transmission that enables electric power generation (up to 100kW). By using this electricity farmers could power implement fan drives, take the place of implement hydraulic pumps, or assist the tractor by powering the implement’s axles. This is similar, to the proven technology John Deere currently uses, on construction equipment.”

Jardon said.

Agricultural implements with powered axles are already successfully used in Europe to help push the tractor from behind while working in the field.

“EVT technology offboards electricity from the tractor to provide added power to the implement and can reduce wheel slip, improve up-hill performance, and enables the tractor to pull wide implements without the need for extra ballast or a larger tractor,”

Jardon said.

For MY 23, John Deere 9R 640 and 9RX 640 Tractors will now also be powered by the all-new, completely redesigned JD14X diesel engine producing 640-rated horsepower. MY 22 390- to 590-horsepower 9 Series Tractors also use this engine across the entire lineup of 9 Series Tractors, including the 640-horsepower models. Based on internal testing, the JD14X engine in 9R 640 and 9RX 640 Tractors uses 7% less fuel than previous models.

“These new engines were built for outstanding performance, greater reliability and we have made them easier to access and service. The engine features a 500-hour oil change interval, hydraulic fan drive, and a high-pressure common-rail fuel delivery system for increased fuel atomization, efficiency, and power, along with faster start times. Customers told us they appreciate the lugging capabilities the new engine has brought to their 9 Series Tractors.”

Jardon said.

Worried that a mid-size dozer won’t have enough power for your bigger jobs? Komatsu’s D71EX/PX-24 with the most powerful hydrostatic transmission (HST) dozer in its size class is effective at grading, pushing, side-cutting, and work on soft ground, giving you the flexibility to move from production to finishing with a single machine.

Pushing with 237 horsepower, Komatsu’s largest HST dozer [49,824 lbs.- 50,927 lbs. (22,600 kg – 23,100 kg)] helps operators maintain ground speed while operating under heavy loads in H mode. Its distinctive slant nose design offers outstanding visibility to the cutting edges and excellent balance and maneuverability.

Offering precision on the job site, from golf course construction to highway projects, the D71-24 is an all-around crawler dozer. It is equally adept at precise, high-speed grading and rough dozing, and is designed to provide outstanding wearability and functionality with its high-capacity, wear-resistant dozer blade. The dozer’s Parallel Link Undercarriage System (PLUS) features rotating bushings to help minimize maintenance downtime and the cost of ownership.

D71-24 and intelligent Machine Control, iMC 2.0

The industry’s newest slant-nosed HST dozer is also available with Komatsu’s latest intelligent Machine Control (iMC) 2.0 capabilities:

• Lift layer control optimizes earthwork productivity with the press of a button. It maintains compaction quality by automatically controlling lifts to the desired height. Excess fill is eliminated as automatic blade control follows the finished surface once lifts have reached the finished grade.

• The tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. Reduces operator steering input by up to 80%.
• Operators can create a temporary design surface with the press of a button with quick surface creation. Combined with other iMC 2.0 functions, crews can begin stripping or spreading using automated input while waiting for the finish grade model.

• With proactive dozing control, even less experienced operators can automatically cut/strip from existing terrain. The dozer measures the terrain it tracks over and uses that data to plan the next pass, improving productivity by up to 60% versus previous generation machines.
