Hello:

Last spring I bought an 18" gas chain saw, and have used it just a few times
So, I am certainly not an expert with it.

This is probably a bit on the silly question side, but I did see the use of
a chain saw
in cutting up ice blocks, so I guess they do have a bit of versatility.

Anyway, I have to bury a run of about 40 feet of very small diameter coax
cable in my backyard.
Probably 6 inches deep, or so, would do it.
Really don't want to rent a "Ditchwitch".

As the slit I will have to cut in the soil is so thin and relatively
shallow, I was wondering about the practicality
of just using the chainsaw by dragging it over and thru the soil.

Bet it would do a really quick and fine job (maybe).

Assuming no rocks, is this safe ?

Would it hurt the blade or saw ? (doubt that the soil is any more or less
abrasive than wood chips), but...?)

Any thoughts on ?

B.
