I was tired today and clearly hit the dirt for the first time in a while. Finished wrecking a triple stem doug-fir, limbing from the bucket as high as possible, I couldn't tell if any trunks were still interlaced or had branches grow solidly together, effectively cabling the tops, so 50' of leverage and a slight push of the right-hand pedal, and the whole shebang went to the open field. Had a nice tractor to use with a grapple on the bucket.
Its hard to work solo. My supervisor is off this week. I had the park aide as my second on the scene to watch for foot traffic, emergencies, etc. Hydraulics help.
