Variable chamber round baler - SIPMA PZ 2780 SUPRA

The new generation SIPMA PZ 2780 SUPRA baler from series 2000 is a machine featuring a variable chamber, which allows to adjust the diameter of the formed bales. Its advantage is its versatility - it performs well both in the harvesting of straw or hay, as well as green fodder for silage.

• Variable chamber based on five seamless belts to form bales from 0.9 to 1.8 metres in diameter.
• New, reliable 2,2 m wide camless pick-up with pressure roller and pneumatic wheels.
• New high-performance feeding and shredding unit with tilting floor system, equipped with 15 knives, each with individual mechanical protection.
• Thepick-up drive is equipped with a semi-automatic clutch for overload protection and the highest safety requirements.
• Reinforced drive, thanks to the increased strength of the main gearbox, the use of spherical roller bearings at key nodes and reinforced bearings on the belt guide rollers, the use of reinforced chains from renowned manufacturers.
• New, reliable chain lubrication system based on a mechanical pump with the possibility of setting an individual oil dose for each chain.
• Longer drawbar with the option of fitting it with 40mm Ø, 50mm Ø hitching eyes and a K80 ball and equipped with a shaft support to ensure its stability when the machine is uncoupled from the tractor. 
• "OptiFlow System" for the maximum possible pressure and short bale formation time with the most optimal tractor power requirements.
• New electronic control system that monitors the entire bale cycle including automatic net wrapping, with the possibility of defining all the machine parameters, such as the degree of crushing for the three layers of the bale, the bale diameter, the number of net wraps and control of the evenness of the chamber filling
• Modernised net wrapper taking into account customer feedback, providing better net feeding and guaranteeing correctly wrapped bales.
• Wide angle PTO shaft with automatic clutch by SIPMA.
• Modern LED road lighting for even greater safety on the road after dark.
• Electronic control is responsible for adjustment and supervision over the run cycle of collection, wrapping and unloading of bales. It also monitors the correct operation of the machine mechanisms.
• Functions of the electronic controller:
  - activation and carrying out an automatic cycle of the machine operation;
  - defining the number of binds of a bale with a net;
  - control of equal spread of material in the chamber;
  - defining a bale diameter and the degree of its compression in three variants:
     1) the core of a bale and its top surface under constant pressure;
     2) separate setting of pressure for the core of a bale and its external surface;
     3) separate setting of pressure of a bale core, external surface and additional increased pressure during the final formation of a bale;
  - supervision and sensor status display;
  - indication of the number of bales made, working time, efficiency.
