VARIPOWER 2 from JAGUAR forage harvesters
The VARIPOWER drive in the SCORPION 741, 736, 635, 1033 and 732 has now been replaced with the VARIPOWER 2 twin motor, designed and manufactured exclusively for CLAAS. The drive integrated into these models as standard comprises two hydrostatic motors inside a compact housing which share a common shaft and swash plate and have been used successfully in the CLAAS JAGUAR forage harvesters for several years. Both motors have a maximum swivel range of 23 degrees, with both traction units controlled by a common distribution unit.
As before, the operator can select three driving ranges – 0 to 15 km/h, 0 to 30 km/h and 0 to 40 km/h – with the simple press of a thumb. A maximum speed of 40 km/h is standard, but there is an option to limit this to 30 km/h or 20 km/h as required. In each case the top speed is reached at a reduced, fuel-saving engine speed.
VARIPOWER 2 transfers just as high torque to the wheels as the previous VARIPOWER drive. The simple, compact design, which dispenses with the need for transfer gears, ensures a high level of wear tolerance and long service life. The new feature is that the housing oil is continuously extracted from the drive housing by a powerful Venturi tube, which significantly reduces churning losses when driving at speed. This ensures maximum efficiency and low fuel consumption even on fast road journeys.
The SCORPION 960, 756 and 746 will continue to work with the VARIPOWER (746) and the high-performance VARIPOWER PLUS drive (756, 960) with wide-angle hydrostatic pump and second displacement motor.
