My brother in law cuts timber and it seems he is buying a new falling saw every year,sometimes not even that long.He keeps 2 saws on his landing and uses Husqvarna 372s to fall with.This may be a rookie question,but would a saw that spends most of its life cutting on its side wear out the right side of the piston or cylinder instead of wearing evenly?Seems like he has had the 2 same landing saws forever.Thanks for any replies
