The last crew on my property dropped the faller of a few properties down from me at 7AM, he walked with his kit doing a 30' wide easement until dark. Support staff(guy in truck) would drop by with fuel/oil, food etc. when the faller requested. Picked up at dark. That fellow cleared a lot of ground in a day and that saw was running other than to sharpen, top off, clear the filter and drink/snacks/lunch. The slash/chip crew followed at a fair distance. None of these folks were $10.00 a hour employees. They did not cut in the freezing rain and heavy snow, but that was the only times I saw the trucks idle during daylight. When contracted distance was felled he would join the one of the slash/chip crews or move to the next contract if it was close enough to be quickly supported.
The slash/chip crews would work under light after dark if needed.
They ran Husky 365/372s.
The last NG easement I was at was being slashed and chipped after dark under lights, looked like an X-files episode coming over the hill. They were running 362s.
Abuse and use are fairly easy to differentiate. If they have contracts and the weather is good they run crews 7 days a week, muliple shifts if needed.
