Geez guys... forgetting everything about an old machine the moment you stop using it? Son, I am disappoint.
Davykinz: the old Forestry farms and harvesters are side sensitive. On the logger, apples and spalings come out the top (and only out the top), while wood comes out the side (and only out the side). In your screenshot, you only have a pipe on top of the logger, and therefore you're not getting wood output. Additionally, the harvesters will eject into adjacent chests only when there is no pipe connected to it anywhere (just for the sake of completion, as that's something that used to leave me headscratching back in the day).
The side sensitive output is useful for some builds, and inconvenient for some other builds. If you are playing solo, you can change the behavior in Forestry's config file:
In /config/forestry/common.conf, find harvesters.sidesensitive=true and planters.sidesensitive=true, and set them to false.
Other than that, I recommend you look into Forestry's new Multifarms sometime. You can still use the old ones because you are still on Minecraft 1.4.7 with the Ultimate pack, but in newer versions of Forestry the old farms have been removed. Better get used to the new ones. You can find info about them on the Forestry wiki.
EDIT: Sniped by Skirty. Good job, at least one person remembered!
