Thanks for the safety reminder, I've spent 45 years with a chainsaw in hand and I absolutely need to tell myself that safety reminder every time I go out. Logging is the second most dangerous occupation, right next to being president. Cutting saplings removes the danger of falling trees, but not the danger of kickbacks etc.
I know exactly what you mean about not wanting to be a sidewalk superintendent, how do you tell "an expert" that he's not operating correctly? Before he started we were discussing the project and I told this guy, I'm not trying to tell him how to operate his machine, but I think straight forward runs up and down the slope are going to work the best, but he could not seem operate without backing up and turning all the time. His thing was to run into something for a bit, then back up to see how his work looked thus far, turn a bit and approach from a different angle. Not a good thing with 5" sapling pieces getting in front of the sprockets with rubber tracks.
And you being a lifelong heavy equipment operator that probably knows more about heavy yellow metal than most guys would also know that one of the first things they teach an operator is to "not excavate in reverse". And the second might be that "production is a lot greater with long passes" rather than short choppy turning movements that change direction a lot. But the whole truth of the matter is that the project needs a bigger forestry mulcher machine with steel tracks. However, my budget for this already took a big hit with two days of failures, the clock kept on ticking while we were spending time putting tracks back on and the second day very little work got done but the invoice was high.
I can cut trees by hand with a chainsaw just as fast as this $250 an hour machine was knocking them down, and since my time is free, and the chainsaw costs about $2.50 an hour to keep running, I can work for 1/100 the cost at about the same speed, and the "timber stand improvement" is actually better because with me being more knowledgeable in identifying trees than my operator was, I can be more selective in what I chop down. I'm looking forward to getting started, and maybe I'll stretch this out over multiple years, kindof like
