New Holland BB9090 baler receives a big boost
New Holland's 2008 big baler range will be topped by the new BB9090 large rectangular baler, which replaces the BB980. The new baler represents a significant advance over the previous model, with increased performance and serviceability.
The updated styling benefits from its wide opening side doors offering easy access for servicing and reduced trash build up. Available in a single or steered tandem axle with independent leaf spring suspension, the BB9090 baler can be specified with hydraulic or pneumatic brakes.
Development of the baler's main drive has increased plunger speed to 33 strokes per minute and extended the crank arm length by 20mm, increasing baler capacity by up to 20%. Bale width has also increased from 1180mm to 1200mm. A 35kg heavier flywheel and a move from four to five friction plates in the flywheel slip clutch results in more inertia for the plunger, a smooth application of power and longer service life.
Baler hydraulics, similar to those used on BB-A models, are now self-contained, making the BB9090 independent of fluctuations in tractor hydraulics. The double-acting density cylinders allow the top tension door to be opened, removing all tension on the bale for easy bale removal.
Pick-up performance has been enhanced with a new flotation system integrated into the baler design. Replacing the spring flotation, the pick-up now has greater terrain following capability and can be raised higher for improved ground clearance. Heavy-duty 5.6mm tines provide reliable operation. The new plate windguard and double augers offer superior crop feeding in all conditions.
The BB9090 baler's knotter configuration has benefited from a number of changes that improve efficiency and reliability. A standard new full-width, centrifugal knotter fan is driven hydraulically for improved efficiency. Knotter shaft and sprocket bearings are sealed, reducing the need for greasing and a new knotter autolube system can be set by the operator from the control panel, further reducing maintenance times.
The bale length metering wheel is now centred in the bale chamber, ensuring good traction in all crop conditions for improved bale length accuracy.
With the BB9090 expected to perform long hours for contractors, reliability and easy servicing is paramount. The stuffer pivots on sealed ball bearings, eliminating the need for greasing while the stuffer cam track bearings are now supported on both sides of the cam arm assembly, providing better support. Lubrication intervals have been increased from 10 hours to 50 hours and the number of lube points has been reduced, bearing type has been improved and more bearings are now sealed, eliminating the need for the main autolube system.
Three new work lights placed under baler shielding provide clear illumination for twine loading and servicing at night. Twine capacity has increased from 24 balls to 30 inclined balls, which reduces storage space and improves access. The twine boxes are sealed to reduce the build up of debris.
The new colour ISO 11783 compliant monitor is bright and easy to read in all light conditions, providing the operator with detailed information. Strokes per flake, flakes per bale, bale chamber pressure and clutch slip are available, while a detailed bale count system allows seasons, customers and jobs to be recorded.
