I have a McCulloch out in the barn. When I needed it last time, I was looking for parts (about 5 yrs ago). McCulloch is no longer. The brand was sold off to someone. I don't remember who. I was looking for a new bar, chain, brake etc.
I ended up buying a new one. The McCulloch is my dirt saw. If I am going to possibly hit dirt, I just run that one. The bar is so worn that If I try to go through a 8" log, it will curve the cut and eventually go down the length of the tree instead of through it.
It wasn't worth selling, so I just keep it for the bad work.
