This is a gravely front mount chain saw. It has been stored in my dads shop all its life and we used it about 10 years ago and it worked great. It has the proper drive unit attached and the chain is in great shape just needs a little sharpening I would imagine. It cut really well the last time we used it. I don't have a factory oiler, we never did, but I can show you how to rig one up real easy. Just a squirt oil can and some plastic tubing is what we used. We have used it on a walk behind and on a 430 we had with no problem. Must be picked up too heavy to ship . It's in great shape so get in touch if interested. Just call me on the phone no texts or messages.
