Just over a month until the official trade fair presentation, the Carraro “Hybrid” tractor is already being talked about having received two important awards from FederUnacoma: the award for the EIMA 2018 Technical Innovation and the EIMA 2018 Blue Award. An excellent assertion for a concept vehicle which is extremely innovative and one of a kind in the specialized tractor sector.
At first glance, the differences compared to a conventional tractor are hard to see: the same layout, typical dimensions, powertrain equipped with a synchronized mechanical Carraro 24 + 24 drive line which keeps its structural function. The controls and user interface in the cab are also "traditional."
The innovative element of the project, developed in collaboration with 4e consulting, involves the creation of a system which integrates the downsized diesel cycle endothermic engine and a 105 hp electric motor as the powertrain of the vehicle, with the main aim of allowing rational use of the power output based on the different working requirements. The auxiliary systems are managed by the respective electric motors, allowing further rationalization of uses.
Thanks to this propulsive architecture, the user can decide whether to proceed in pure electric mode (for example, in greenhouses, stalls, or in centers) , in diesel only mode (for example, on roads) or whether to exploit the power of the two integrated engines in hybrid mode (for example, if towing or carrying out heavy PTO work).
The technical solution selected will also allow a significant reduction in tractor emissions and consumption. This is also true of maintenance interventions, which are reduced thanks mainly to the fact that the endo-thermic engine is used less frequently.
More detailed information on the new Carraro "Hybrid" tractor will be made available during EIMA, which starts on November 7, 2018.
