Intelligent vibration damping for large square balers
Large square balers enable high transport and storage density of plant material and therefore have achieved major importance in agriculture. However, due to high inertial and pressing forces, these big balers induce vibrations that subject the tractor cab to unpleasantly strong pitching movements, which put a strain on the tractor driver.
With intelligent vibration damping, these vibrations are almost completely eliminated on models of the 7R tractor series in conjunction with balers from John Deere. Based on the signals of the acceleration sensors in the GPS receiver and other signals within the tractor, the continuously adjustable drive is adjusted with the plunger frequency of the baler so that a periodic change of the speed setting compensates for the vibrations created. No additional hardware is required for this purpose.
This technology specifically developed for active vibration reduction means a considerable relief for the health and performance of tractor drivers

Baler Control System for the T7-Traktor
Large square balers enable high transport and storage density of plant material, and therefore have achieved major importance in agriculture. However, due to the high inertial and pressing forces, big balers induce vibrations that subject the tractor cab to unpleasantly strong pitching movements that put a strain on the driver.
To reduce this vibration load, a baling mode can be selected on the New Holland T7 tractor series. This modifies the coordination of the front axle suspension and increases the slope of the limiting curve on the engine map. This then avoids oscillation of the tractor-implement combination, the system decouples and a considerable reduction in the vibration load results. No additional hardware is required for this purpose. This passive system is compatible with balers from any manufacturer.
This technology, specifically developed for active vibration reduction, means a considerable relief for the health and performance of the tractor driver.

Innovative driveline for HD big balers
Big balers that produce high-density bales require a high-inertia flywheel and a powerful plunger to suit. Therefore, protective start-up systems are required to prevent the tractor from stalling or the PTO shaft from overstraining when the baler swings into action.
The common cure is either using a hydraulic start-up system that operates at a lower torque, or switching from the 540rpm PTO to 1,000rpm. CNH and Walterscheid developed a new driveline where, relative to the current tractor torque, the gearbox shifts up into the desired flywheel speeds. The feature is called “Power Shift Function”, and it allowed the developers to increase flywheel speeds and baling output while reducing flywheel inertia and dimensions. The shifts are made by internally cooled multi-plate clutches. A multi-plate brake with internal cooling, which is also integrated in the gearbox, slows down the plunger when this is in its optimum starting position. It also serves as an emergency brake that brings the plunger to a stop within eight seconds. The system also reduces the risk of fire because it removes the flywheel brake from a dusty environment. The necessary service modes are also selected via this intelligent control system.
The new drive concept for big balers assists the tractor PTO in starting the heavy flywheel,l thereby protecting the tractor and the PTO clutch. The brake that is now integrated in the gearbox brings the flywheel to a safe and effective halt and significantly reduces the risk of fire.
