Updated November 11, 2014 - Thanks to Alraris for making me aware the logs were not working for businesses.
You find this item under Knowledge/Misc for $100. Sims chop wood to gain body skill, enthusiasm in nature and fun, they also, earn logs which go into their inventory, each set of logs may be sold for $100. Their energy, and hygiene are reduced while chopping the wood. Body temp increase. After 8 times of chopping wood, the fallen tree will disappear.
The Pine Tree textures are pulled from EA's Pine Tree.
Custom Sound and animations.
Note: If you have my fallen birch tree you may remove the hatched and sound files as you do not need two.
This Pine Tree works the same as my Birch Tree as seen in this video.
