Description
Drever 120 enables fossil-free, sustainable agriculture by working 24/7 powered by electricity. Drever 120 is smaller than today’s machines and thus creates less soil compaction. Drever 120 is however large enough to fit in heavy tillage in large-scale crop production. Drever is autonomous and each battery pack lasts 4 to 12 hours dependent on the type of work. One battery pack is on charge while the other is used in the machine. The big battery packs can store energy on the farm or provide services in the grid. Drever 120 is pulled to the field by a tractor and the battery packs are swapped by forks and a wheeled loader.
Drive train type
All electric with 600 VDC battery swap system. Individually controlled hub motor in each wheel, electric three-point and electrically powered hydraulic system.
Characteristics
Drever 120 has pulling power equivalent to a 150-horsepower diesel tractor and productivity over a season like a significantly larger tractor. Electric three-point hitch with three tonnes capacity. Four double-acting hydraulic outlets and one electric power outlet.
Navigation system
Web-based planning system. ROS-based navigation system. LiDAR and safety bumper combined with geofence as a safety system. 360-degree camera system.
