Bucking and Limbing Fallen Tree

What happens here

After the tree is felled, the presenter uses the Stihl MS 661 chainsaw to cut the trunk into manageable logs (bucking) and remove any remaining branches (limbing). He mentions the impressive power of the chainsaw, noting it 'chews through' the hard oak like butter without bogging down. Once the tree is cut into sections, he prepares for the cleanup phase.

Goal: Process the fallen tree into logs and remove all remaining branches.
