It's really hard to say, it depends on whether you unload on the go, travel home at night or leave the machine in the field, move between fields a lot and so forth. I've found that 1 in every 10 engine-hours is a non-separator hour, thus, for every 100 hours worked, deduct 10. That's what we always did for custom combining with 1440's and 1660's.
