This is what they are talking about when they say "agricultural variable speed" on pages 2 and 9. Combines (and other ag machines) use continuously variable drives to adapt travel speed to thrashing speed, etc. These applications are particular demanding and require tough belts, which you would expect to have high bending losses (typically) high bending losses.

Here's a vendor for such belts:
Variable Speed Belts - Quality Power Products

This describes how these drives are used.
