John Deere Unveils New Engines at ConExpo Las Vegas
The recent ConExpo construction show held in Las Vegas, said to be the largest exhibition of its type in the world, saw John Deere Power Systems (JDPS) preview two new mid-range industrial engines.
Full details are scarce, but an 8R with an electro-mechanical eAuto-Powr transmission is claimed to be the first IVT (infinitely variable transmission) of its type.
Rural News understands the layout of the new gearbox sees the integral hydraulic motors being replaced by electrical units, while an integrated generator will deliver 100kW (135hp) for secondary/external use.
To demonstrate the concept, John Deere has partnered with Belgian company Joskin, which has created a modified version of one of its tri-axle slurry tankers. The unit has both rear axles driven electrically, effectively creating an 8WD combination.
The companies say this will increase traction and reduce wheel slip, while at the tractor end the electrical portion of the gearbox will improve efficiency and reduce maintenance costs.
