Ok, for all you super-duper groundmen, here is how I do tree work:
Small trim jobs, cleaning up small storm damage: chipper truck, climber & one groundman.
Medium trims & removals, easy work or more than 2 hours on site: bring two groundmen. Get it done quicker!
Bigger jobs, including all day at one site for removals, multiple trims, or technical work involving extensive roping and dragging: 3 groundmen. two to drag & chip, one to rope and do extra work. Add a truck to haul logs or swap into the chipper if volume is high. Make SURE you get done in one day.
Large removals: Add a Bobcat A300 to haul brush and logs to the truck. Why kill off the groundmen hauling 5 tons of wood?
Apartment complexes, land clearing, major projects: 2 climbers, 2-4 groundmen, not less than two trucks to haul wood/chips, A300 to move large volumes of wood, perhaps a rented aerial device to speed up the climbers. Add a tree shear, and bring along the 5603 John Deere tractor with the brush grapple to handle large volumes of trees, or long hauls to the brush pile.
Every project gets what it needs, guys. I'm not so dumb that I throw the same amount of people & equipment at every job we do.
