They're here to cut down the dead maple tree. The trees lining this street were planted when the houses were built. This one must be at least 100 years old.
The cherry picker lifts the skinny chain saw guy to the top of the tree and he starts cutting the main limbs, which are lowered to the street by a mobile crane.
The branches are fed into a shredder that chews them into sawdust instantly.
The final trunk is cut and lowered onto the flatbed with the rest of the wood.
The chain saw cuts through the wood as if it was butter, or jello.
They have trimmed the dead top branches of one 75' high maple, and completely removed another. They have swept and vacuumed the street, and there's not a twig or a grain of sawdust left to show that they were there.
Just a stump remains.
