Krone and LEMKEN literally combined powers to present a new autonomous system called Combined Powers. In this joint project an autonomous process unit consisting of a drive unit and various implements was developed.
After passing trials in cultivating, ploughing, sowing, mowing, tedding, and raking last year, the innovative 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 170 kW, the drive unit is designed to meet the power input requirements of the implements. 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.
Multiple sensor systems monitor the immediate surroundings and the implement attached. 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 speciality 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.
Intensive trialling in all types of conditions and seeking feedback from farmers and contractors will continue this year. Further information is available at www.combined-powers.com. (Source: Combined Powers)
Even more section control
Section control on Valtra tractors has previously been able to divide an ISObus-compatible machine, such as a sprayer, into 24 or 36 sections. The latest version increases this to as many as 96, while the Multiboom feature makes it possible to simultaneously control up to three different booms fully automatically.
The function will be ideal for controlling ISObus-compatible seed drills, sprayers, fertiliser spreaders and row crop cultivators. Sections on the new version can be controlled by separate feeders in one, two or three consecutive rows. Alternatively, one implement can be in front of the tractor and the other at the rear.
On a seed drill, for example, fertiliser can be spread in the first feed system, seed in the next and starter fertiliser or small seed in the third.
“Depending on the implement, the seed and fertiliser hoppers are often divided between two or more sections,” says Product Specialist Johan Grotell. “Section control 96 can control each of these sections and feeders with centimetre accuracy.”
Operated from the touchscreen on the SmartTouch armrest, the interface is similar to the existing one (the tractor must have auto guidance and ISObus implement control). (Source: Valtra)
The new JUMBO 8000 chops much shorter
The JUMBO 8000 high-performance loader wagons from Pöttinger chops forage almost 30 percent shorter: This means even higher forage quality without compromising on loading performance.
Protected to a torque of 3 500 Nm, the loader wagon can now deliver higher throughput rates than a self-propelled forage harvester.
Currently chopped lengths of 34 mm are possible with loader wagons. Thanks to the new drive concept, the rotor, and the chopping system with 65 knives, the JUMBO 8000 can now chop to lengths of 25 mm requiring only 15 percent more power.
The knives are individually protected and can simply move out of the way of foreign objects.
The automatic loading system now features an additional optional sensor on the rotor scraper carrier. This means that up to four sensors (torque on the rotor, hydraulic pressures, material loading, et cetera) are used to optimise the loading process.
The new sensor system detects the pre-compaction of the forage directly above the rotor and activates the scraper floor before any mechanical damage can occur. As a result, the JUMBO 8000 can always make optimum use of the space inside the loading chamber, regardless of the type of crop.
When harvesting grass silage, every farm manager wants to obtain the highest possible forage quality to increase profits. One of the main factors influencing feed quality is the theoretical chopped length. This is the advantage of the loader wagon with its short chopped length.
Short chopped forage can be compacted better, which leads to a quicker decrease in pH value. This reduces the risk of fermentation failure and has a positive effect on the stability of the grass silage and therefore on livestock health and performance.
Another yield-boosting advantage of a shorter chopped length is the 10 percent higher loading density compared to a loader wagon with a chopped length of 34 mm. The higher payload also adds up to greater cost effectiveness thanks to the higher density.
Despite the relatively small knife spacing of 25 mm, it is still possible to use the AUTOCUT automatic knife sharpening system. This saves diesel as well as time. AUTOCUT guarantees the knives are always sharp during operation. The power requirement and the fuel consumption can be reduced by up to 20 percent as a result.
The new technology will be available from August 2022. (Source: Pöttinger)
John Deere goes electrical
Autonomous electrical vehicles seem to be in the development scope of all major agricultural companies.
John Deere has released a video of a fully battery-powered tractor known as the SESAM2.
This latest concept, which can also work autonomously, is a further development of the SESAM (Sustainable Energy Supply for Agricultural Machinery) project first previewed at SIMA 2017. The diesel engine in a normal 6R was then swapped for a 130-kWh battery pack with four operating hours.
The SESAM2 prototype not only looks different, but has a much larger 1 000 kWh battery pack. 500 kW go to the all-electric powertrain with 500 kW available to power external machines. This extra power should allow SESAM2 to work for up to 10 hours at 80% work capacity with a full battery.
A detachable cab and wireless communication from the machine are part of SESAM2, allowing for manual or automatic control – with or without cab.
In the field, the cab can be dropped off on the headland allowing the operator to keep an eye on the tractor and make adjustments where necessary. One operator can monitor and control multiple machines working in the same field.
