4 hour run time? Cool, go home at lunch time and come back tomorrow.
We use ours four days per week for about an hour, maybe two. I suspect there's a lot of others that don't dog a machine 8 hrs or more a day. Farmers mucking out stables in the morning, that sort of thing. We've most certainly done long days when doing construction, but 99% of the time it's loading or unloading a truck, moving some stuff around, spreading some cinders, whatever.
