Gridtractor, Monarch Tractor, and Borg Warner have achieved a significant milestone by successfully demonstrating Vehicle-to-Grid (V2G) capabilities utilising a Monarch MK-V tractor, a Borg Warner 60 kW DC fast charger, and Gridtractor’s cloud-based charge management system employing the Open Charge Point Protocol (OCPP)
Krone and Lemken, through a joint project, have launched a design concept – Combined Powers – which is an autonomous ‘process unit’ consisting of a drive unit and various implements
After passing trials in cultivating, ploughing, sowing, mowing, tedding and raking last year, the concept will be integrated in the well-proven forage harvesting and tillage systems of the two companies.
Using a diesel-electric drive that generates up to 170kW (230hp), the drive unit is designed to meet the power input requirements of the implements used in the processes above. The drive power is transferred electrically to the wheels and the pto and from there to the implement which couples to a three-point linkage. The drive unit boasts multiple and extensive sensor systems which monitor the immediate surroundings and the implement attached, ensuring safe operation and optimum results as the primary objectives. Operators control and monitor the combination from a mobile device, transmitting jobs and job reports via a communication module and the agrirouter, the established data exchange hub.
The specialty of the process unit is that it is controlled by the implement and not vice versa. This detail was considered imperative for achieving optimum results. The implement and the drive unit act as one integrated smart system. Based on the long experience in the application of ISOBUS and TIM on Krone and Lemken machines, the drive unit and implement communicate and interact, sharing literally all types of data.
The Combined Powers design concept also brings further benefits, because it was also developed to counter the increasing shortage of skilled labour in agriculture. Also, it will free farmers from spending those long days in the field. Instead, they will become system operators who merely monitor the process unit which delivers a consistently accurate quality of work. Thanks to its enormous versatility, the unit is designed for year-round work and a long service life. Intensive trialling in all types of conditions and seeking feedback from farmers and contractors will continue this year.
