Engine power is transmitted from the engine through the right-angle bevel gear case and through the main clutch to the power band. This power band drives the crop accelerator and cutterhead. The cutterhead shaft transmits power through the Infinitely Variable Length Of Cut-(IVLOC™) transmission to the feedrolls and the header. The kernel processor is driven off the crop accelerator.

• Simple drive system is very reliable
• No chain drives to maintain, saves time
• Field proven components are very durable

Bevel gears transmit engine power smoothly onto the main clutch pulley. The bevel gear housing absorbs loading of the power band and enables the use of a short power band. Hydrostatic drive pump, hydraulic main pump and hydraulic Infinitely Variable Length Of Cut- (IVLOC™) pump are flanged to a carrier housing, adding more reliability.

• Bevel gear housing de-stresses engine
• Belt tension loading is not transmitted to the engine crankshaft. Long trouble-free engine service life is ensured
• Requires no maintenance, no belt or chain drive, no wear

The multi-disc wet clutch features a large surface area and wear resistant clutch disks for smooth engaging and durability. The clutch is operated with low hydraulic pressure.

• Field proven wet clutch is very reliable
• Large surface area provides long service life
• No maintenance, no adjustments required

The main power band drives all components other than ground drive. Power band tension is applied through a hydraulic ram whenever the engine is running. This active hydraulic tensioning automatically adjusts the band to provide constant belt tension, even during momentary peak loads. Power band is made of Kevlar-reinforced material. The 7250 uses 4 strand power band, 7350 uses 5, 7450 uses 6, while 7550 to 7850 uses 7.

• Power band is not under tension when the harvester is not in use - longer belt life
• Automatic belt tensioning reduces belt whip which would lead to premature wear
• Easy to maintain and service for more up time in the field
