Air Impeller

[freds]

I went by Lowes and spun the impeller on a new unit. Really about the same amount of spin friction ours has.

Do you think the weight of the chain is causing a waste of energy. What if we used the green belting? Would that help?

Also, went by Home Depot as well, both Lowes and HD have the Dewalt unit GMST is using. I will bring one on Sunday for backup use.
