Fabs, look at the cutter teeth and see about the cutting edge, Cutting into earth or dirt is hard on a chain. You might be able to touch it up with a file, if not heavy damage. Or just take it to the shop and have them sharpen it on a cutter wheel.Never try to force a chain to cut, it should be pulling strips, not making sawdust..
