DRIVE SYSTEMS
Axial-Flow® 20 Series combines feature exclusive Power Plus Continuously Variable Transmission (CVT) drives – with a dedicated drive for the rotor and a separate drive for the feeder.
 
The Axial-Flow 88 Series rotor drives feature Kevlar belt technology with extra large pulleys. An exclusive three-speed gearbox provides maximum belt wrap while ensuring efficient power transfer from the engine to the rotor.
  • 5088: 2.5-in. (6.4-cm) rotor drive belt
  • 6088 and 7088: 3-in. (8-cm) rotor drive belt
A field-proven Feeder Drive system on Case IH Axial-Flow combines gives you the power and torque you need.
