*The figures in parentheses indicate lines of this document.
**Nonproductive time includes time used in transport to and from the work site, refueling and greasing
equipment, and making repairs and adjustments. This time is subtracted from the normal 8-hour day to
derive "productive operator-hours per day."
***Computed on an hourly basis for tractormowers if they are the prime movers of the mowers to and from
the work site. The tractor-drivers' time is included in the 2 hour "nonproductive time" or in-transit time
and is therefore not included again in 4g.
