With the development of an electrified mulcher with sensor monitoring, Müthing has made a pioneering step towards autonomous crop residue management in cooperation with AgXeed. This mulcher seamlessly communicates over ISOBUS with the AgBot from AgXeed based on the principles of 3A (ADVANCED AUTOMATION & AUTONOMY), thus paving the way for fully autonomous crop residue management in the agricultural sector.
The current capability for partially autonomous crop residue management using the AgBot includes the use of conventional mulching technology thanks to the standardised interfaces on the vehicle. The operator does nevertheless remain responsible for monitoring the implement and ensuring that the desired work results are achieved. However, the overall concept aims to relieve the stress on the operator due to the fact that recurring processes take place on a fully autonomous basis. In order to implement this vision, Müthing has developed an electrified mulcher equipped with the necessary sensor systems to detect faults and prevent the risk of machine damage.
The mulcher monitoring system includes the following features:
- Monitoring of the output and temperature of the electric drive
- Monitoring of slip and rpm fluctuations on the belt drive
- Vibration monitoring of the mulcher
- A control unit for data recording
- Communication between the AgBot, mulcher and software takes place based on the principles of 3A
The implement monitoring system constantly checks whether the work process is running within the specified boundary parameters or whether overloads are occurring. If there is any excess vibration due to contact with foreign objects or if the drivetrain is overloaded for an extended period of time, the machine is automatically stopped and the operator is notified.
The long-term goal is to be able to perform the work on a fully autonomous basis and without any machine stoppages through intelligent monitoring and control combined with continuous adaptation to the local conditions. In future, the autonomous unit should be able to automatically adjust the driving speed depending on the quantity of biomass. The autonomous unit then only has to stop in unpredictable situations, if damage occurs or in emergencies.
An e-Mulcher is currently undergoing practical testing and has processed around 700 hectares together with an AgBot since autumn 2022. Further machines will enter testing in 2024.
The Müthing trade fair team at Agritechnica 2023 is looking forward to assisting and advising the visitors and providing information on all aspects of autonomous mulching at Stand B33 in Hall 11.
