A blockage of hoses can lead to less area coverage, and less uniform spread. The driver often has to get out of the tractor cab and check that all hoses are unblocked.
Monitoring the flow in each spreading hose is the design aim of the award-winning Flow Check from German firm Josef Kotte Landtechnik, which has won a silver medal for innovation at the Agritechnica show in Germany (Nov 12-16).
This sensor monitors flow in each hose. Where a blockage interrupts the slurry flow, a buzzer alerts the driver, and an LED display shows which hose is clogged.
The driver can then clear the blockage and continue without having to worry about blockages going unnoticed. The sensor is housed in a box which can be power washed. There is no slurry-sensor contact, the sensor it-self will not cause clogging. It can be retrofitted.
¦ Distribution of chopped material such as straw on the soil surface is a commonplace soil improvement routine in intensive tillage. When a very wide harvest working width is involved, achieving uniform distribution of material on the soil surface presents a challenge, which is increased by side winds and slopes.
Up to now, drivers had to visually check the throw direction of the material, using a rear-view mirror or camera, and take corrective action if necessary. In windy conditions or on a slope, the driver has to frequently change the direction of the throw.
The Agritechnica silver medal winning Wind and Slope Incline Sensor from Claas is located on the combine’s two rear lighting arms.
The side wind is recorded, and the slope incline is measured, and the straw spreader automatically adjusted to throw the material against the side wind or up-slope.
It’s the first combine harvester technology for uniform distribution of material such as straw onto the soil surface.
¦ A twin front PTO shaft for cable and winch drive on forest tractors is an Agritechnica silver medal for innovation winner for Zuidberg Transmission of the Netherlands and the German Kotschenreuther forestry tractor company.
This is the first front power take off in the sector that allows for selection of either 1000 or 1000E RPM.
The two stage PTO shaft transmission can be switched via radio. The engine RPM can also be remotely fine adjusted. It is possible to work with the front cable winch at low load with either lower engine RPM or higher skidding speed.
Independent research has shown that using the switchable twin PTO from Zuidberg can lead to a fuel saving of at least 10%.
The twin PTO offers high flexibility and comfort to the operator.
If the front PTO shaft is not required, an automatic function switches the engine off after three minutes.
