I'm failing to see the problem there. That looks like a pretty good rotation to go through. One saw gets tired you grab a fresh one. Minimal down time because of touching up or topping fluids or both.
Similar principle when I go prairie dog hunting. One rifle's barrel gets hot, put it down and grab another one. That way you are always in the game.
Yes you have to have a spare or two or three.
As you can see that particular day was a Stihl day,
We have Dolmar day,Husky day,etc some days we have mixed days however when the Stihl and Huskies are together, they fight and sulk and some refuse to start,so we cart them on separate vehicles to the bush and fire them up before they realize what's going on.
