The New Holland 2008 large square baler range will be completed by the new BB9090 baler, which replaces the BB980 model. Thanks to its increased performance and easier maintenance, the new baler offers significant advantages over the previous model.
The baler's new design has the major advantage of wide-opening side doors, which make maintenance access easier and reduce the build-up of debris. The BB9090 baler is available with a single axle or a tandem axle with steering and independent leaf spring suspension.
Thanks to the development of the baler's main drivetrain, the plunger frequency has increased to 33 strokes per minute and the length of the gearbox drive crank has been increased by 20 mm, thus increasing the baler's capacity by 20%. Bale width has also been increased, from 1 180 mm to 1 200 mm. The flywheel, made heavier by 35 kg, and the change from four to five friction discs in the torque limiter contribute to a smoother plunger action.
The baler's hydraulic circuit, identical to that of the other BB-A models, is now independent; as a result, the BB9090 is no longer subject to fluctuations in the tractor's hydraulic circuit. The density adjustment cylinders are double-acting and allow the upper part of the channel to be released to eject the last bale.
Pickup performance has been improved by a new suspension system integrated into the baler's architecture. Thanks to the replacement of the spring suspension, the pickup now has an increased ground-following capability and a higher lifting height for better ground clearance. The robust tines, 5,6 mm in diameter, ensure reliable operation. The new flat windguard and the twin augers contribute to better crop feeding in all conditions.
The knotter configuration of the BB9090 baler has undergone a whole series of modifications that improve efficiency and reliability. One example is the new knotter self-lubrication system, which the operator can adjust from the onboard computer.
The metering wheel that controls bale length is now located in the centre of the bale chamber, which ensures good traction in all harvesting conditions for more accurate bale length.
The BB9090 model is designed to allow contractors to work long hours; this is why reliability and ease of maintenance are essential. Lubrication intervals have been extended from 10 hours to 50 hours and the number of lubrication points has been reduced. The higher-quality bearings used therefore make a central self-lubrication system unnecessary.
Three new work lights have been fitted under the baler's cover to provide powerful lighting for loading twine and for maintenance at night. Twine capacity has been increased from 24 to 30 angled bales, which reduces storage space and improves access.
The new colour monitor, compliant with the ISO 11783 standard, is bright and easy to read in all lighting conditions, so that the operator has detailed, instant information. The number of strokes per slice, the number of slices per bale, the bale chamber pressure and the torque limiter can be displayed, while detailed bale count reports make it possible to record the year, the customer and the field.
