$50/man hr is roughly the same as the going rate here, for personel plus chipper and truck. Bring in a crane, bucket, lift, log truck etc and it changes the whole equation. If I go to a job that would take 4 hours climbing and do it in one hour with a lift, the price is the same. I just saved time on it so I can do more in a day, therefore it's more per hour but the same cost to the customer.
