Picked up a Stihl 192 arborists chainsaw yesterday. Cutting all the small limbs with the Stihl 250 got to my back and was too clumsy. The money I saved by taking down the tree myself way more than covered the cost of the saw, and I have an up high severe pruning job to do that will be safer with the arborists saw. Looks like I've got great weather to attack what remains of the oak.
