New Holland’s 2008 big square baler range will be topped by a new BB9090 model to replace the BB980. New Holland claims to have increased baler capacity by 20% all thanks to increased crop throughput.

Built by AGCO in Hesston, Kansas, USA, the BB9090 is based on Massey Ferguson’s new 2190 baler.

Development of the baler’s main drive has increased plunger speed to 33 strokes per minute and extended crank arm length by 20mm. Bale width has 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 smoother application of power and longer service life.

Baler hydraulics are now self-contained, driven by a pto pump, making the BB9090 independent of fluctuations in tractor oil flow.

Pick-up performance has been enhanced with new torsion bar suspension, replacing the spring flotation system used previously. Combined with an increase in plunger speed, the improved pick-up has enabled the BB9090 to pack material away quicker, thus increasing forward speed & bale density.

Lubrication intervals have been increased from 10 to 50 hours with more bearings now sealed, reducing the burden on the main auto lubrication system. A new automatic greasing knotter system can be monitored by the operator from the control panel, further reducing maintenance times.

Twine capacity has increased from 24 to 30 balls and wide-opening, sealed doors allow easy access for servicing and reduced trash build-up.

The BB9090 will be available with a single axle or steered tandem unit with independent leaf spring suspension.
