John Deere's eAutoPowr
At a recently held sustainability day in Germany, John Deere unveiled the latest updates for its eAutoPowr, electric infinitely variable transmission, the first of its kind in the world and now available for the 8R tractor range.
The electric drive is designed to supply drive to the tractor, while also providing up to 100kW of electrical power to external implements, using two brushless, electric motors, that according to the manufacturer, are “virtually wear-free” and will last the lifetime of the machine.
Working in partnership with Belgium transport and effluent specialists Joskin, Deere has developed a system that allows up to 20% of the electric power to be redistributed to two axles on a Joskin slurry tanker. This is said to increase traction in poor ground conditions or when climbing inclines, helping to protect the land from sub-surface caused by wheel slip.
In other sustainability news, Deere is also aiming to have electric drive alternatives in every John Deere product family by 2026, with a further plan to launch a fully autonomous battery-powered electric tractor in the under- 100hp class with the same timing.
Deere has also been developing a MultiFuel concept to allow its engines to run on biofuels, traditional diesel or fuel blends. The ‘one-tank solution’, is suitable for any fuel in both pure and blended form, including farm-produced plant oils.
In operation, different fuels are recognised by sensors of the standard combustion engine and the exhaust gas after-treatment system. These deliver the data for a mathematical-physical model and for an artificial intelligence – based approach recognising the different fuel mixtures.
Based on this, the electronic engine control unit (ECU) selects the appropriate software setting for optimal engine operation, while also allowing the engine to comply with Tier 4 emission standards.
Global tyre manufacturer Michelin has extended its agricultural trailer tyre range, with the introduction of its new WorkxBib series, designed for tipping trailers, slurry tankers and manure spreaders.
Following the record-breaking success of its hydrogen-powered Hydromax, JCB is ramping up its investment in the business, key to the first major change at the executive level of the business, with George Bamford stepping up to the post of joint chairman, alongside his father Lord Bamford.
During calf rearing, logistics can play an important role in getting the job done quickly and efficiently.
Massey Ferguson has announced a strategic supply partnership with International Tractors Limited (ITL), a manufacturer of low-horsepower and compact tractors, with recognised brands such as Sonalika and Sollis, to expand its portfolio with a new tractor range.
With the biannual Italian EIMA machinery Expo less than a month away, Case IH has taken out a Technical Evolution award for the Advanced Vehicle Suspension system available on its Optum 360–440 series tractors.
The Advanced Vehicle Suspension system, available on Optum 360, 390, and 440 models, responds to changing conditions, automatically adjusting how the suspension reacts to absorbs shocks and controlling vehicle movement.
In operation, sensors monitor the vibrations transmitted from the tractor chassis to the operator cabin, allowing the system to adjust suspension damping in real time. The control system incorporates key priorities, such as comfort at lower speeds and stability as speed increases, while also reacting to factors such as lower tyre pressures, where the tyres absorb more of the initial shock.
Case IH said as suspension requirements change throughout the working day, as tractors move between the paddock and road transport, the system manages suspension response in the background as tasks, speeds and conditions change, leaving the operator without the need to make manual adjustments.
Richard Hollins, Optum series tractors global product manager, said: “Pioneering technology must earn its place in the working day. Farmers and contractors will judge an investment by what it delivers, including manageable ownership costs, dependable up-time and the versatility to tackle different jobs. With AVS, we are putting intelligent control to work for comfort and stability, without giving the operator another setting to manage.”
Organised by FederUnacoma, the Italian Agricultural Machinery Manufacturers Federation, the contest has been part of EIMA since 1986, with the Technical Evolution distinction awarded to products that introduce original improvements to solutions already manufactured or patented.
