A logger planned to work from 6 AM to 4 PM with 30 minutes for lunch, his skidder would have 9.5 SMH per day. If the skidder spent 30 minutes waiting for trees to be felled, 20 minutes replacing a hydraulic fitting, and 10 minutes moving to another landing, total payload is 200m 3 , please calculate the productivity per PMH and MA, UT.
