Self-Propelled Chainsaw Reduces Injuries

I've got two trees on the property to deal with and need to do so in place. This might be my best option.

Are you planning on slabbing up the trees for timber beams and planks?

Both. I need two covers: one for a wood yard and another for a concrete slab for wrenching on the car. The rest are going to the library for shelving. I say the rest, but I have a feeling there's going to be a lot more finished board than I actually need.
