I get all of that Graeme and well said. Using wedges when not needed does equal the downtime of trying to fall a tree that you should've used them on and didn't. Well put. Moving fuel to where you'll need it next takes a lot of experience to get right too.It is a workout but there is no rush, the day is long. With 60 year old legs I "change back a gear" and minimise wasted effort. The natural slope is 25 - 45 degrees and the last few days have been in the 40's deg C, (and there is some donkey cutting down all his shade).
Despite this, when I can get to them through the undergrowth and crap I average a tree about every 4 - 5 minutes for 11 hours a day. 1 hour off for lunch and replace the lost fluids with cold beers end of day.
You have honed in correctly "minimizing time" though cutting wasted time doesn't mean cutting corners. While I am scarfing (notching) a tree I am looking around planning hours ahead of myself. How you move your fuel ahead of the work, cutting bridged logs while you are there and observing future hazards, all adds up. The “alpine ash” bush is unforgiving. All this is done while coordinating with the machines sorting the mess I make below.
The flow of wood onto trucks is the result of great teamwork rather than any individual.
Placing wedges in every tree is as big a waste of time and effort as not putting one in when you need to. Knowing when to is the result of experience. If I knew how, I would put up some short clips of sliding trees down to the landing and other stuff but alas there isn’t a “pull start” on my computer. I had to work a few Sunday’s and not allowed to work alone so I took up an assistant who took some pics. I put 16 litres of fuel through the falling saw so there was a lot going on.
