BiG X 680 | 780 | 880 | 1180

• Simple design
• An extra-strong poly V-belt transmits engine power to the crop assemblies
• Long service life
• Separate drive for the intake rollers and the headers: Rollers and headers are reversible if the chopping
  drum suddenly stops
• Separate and dependable driveline to the ground drive pump

The transversely mounted engine allows the chopping drum and the crop accelerator to take engine power directly off a powerbelt. The engine also drives the pumps for the intake rollers and the header and also the pump for the ground drive and the assemblies. The power flows through a power take-off gearbox which uses a multiplate clutch to engage the assemblies.

Power to the assemblies
The chopping drum and the accelerator are powered by a powerbelt that provides a direct connection to the transversely mounted engine. The accelerator shaft drives the poly V-belt for the corn conditioner on the other side. Slackening the powerbelt to the chopping drum reverses the intake system and the header.

Carefully designed: The header and intake system are driven by oil pumps. This concept allows operators to adjust the header and intake speeds steplessly – ideal for adjusting automatically to varying harvesting conditions.

Optimum ground drive: Courtesy of a hydro pump that is flange-mounted on the main gearbox, Big X changes its ground speed infinitely variably. This is set either automatically or manually from the cab. The dependable powertrain guarantees maximum reliability.

BiG X 680/780/880 are available with hydraulic wheel motors on all four wheels as an option.
