Serbian robotics company Coming has entered the AgAR X4 compact, electric unit into the competition. It offers 12kW of peak power, with an additional 20kW peak at the pto and continuous torque figures of 1,200Nm, with 156Nm at the pto.
The company gives a broad range of working time figures, depending on the operation, with 3hrs in the most intensive situations and a maximum of 12hrs. It takes 3.5hrs to charge from 20% up to 80%, reducing to 2hrs when plugged into a DC fast charger. It also states that the LiFePO battery built into the machine can be easily swapped out, increasing the possible working range, or for easy replacement at the end of the battery’s life.
Wheel motors are provided by ZD Motors, working through a planetary gearbox for maximum speeds of 6kph. Key to its design is the adjustable axle spacing, automatically moving them closer together or further apart to provide additional clearance. This means that the unit can spread its footprint and be closer to the ground (minimum clearance of 220mm) or pull the axles together for a maximum clearance of 810mm when working in mature crops.
It has a low maximum operating weight of 1,350kg, with just over 350kg of lift capacity. The electronic pto runs at 540rpm as standard, with the option of an 800rpm unit.
It can work as a part of a fleet, with full telemetry and synchronisation through a layered connection of wifi, 4G and 5G, with RTK guidance. Through the telemetry system, task data can be shared wirelessly with path optimisation to minimise wheelings on the field.
For safety, the AgAR X4 is fitted with a camera system and Lidar monitoring, as well as a bumper system in case of obstacles. When it recognises or encounters an obstacle, the unit will stop operations and wait for the operator to resume work.
