A 16" diameter tree fell across a stream and a neighbor doesn't like it because leaves, sticks, etc. and some plastic bottles, like retail water bottles, and other soft plastic and a few aluminimum cans pile up behind the log, and she says it smells some times.
1) Specifically, if I cut it into 4 sections, one of the cuts would be where the trash is piled up, above the water line. Is it necessary to get that stuff out of there before cutting? (IIRC the major reason for not cutting a log on the ground was dulling the blade and the saw being pulled out of your hands, neither of which would apply here.)
2) The tree is about 16 inches in diameter towards the roots, maybe 14 inches at the other end 14 feet away. Is it better to rent an 18" saw, which will be heavier and harder to handle, or better to rent a 10" saw which will require two cuts for each cut but will be much easier to handle.
What happens if the chain end of the saw dips into the water while running? Do I just put more oil on the chain and keep going?
Any warnings about using a gas chain saw while standing in the stream?
The log itself is not in the stream, but although I think I can avoid it, it might be after the first or second cut.
I have an electric chain saw that would probably do this, but no way am I going in the stream with that thing, no matter how double insulated it is.
