In 1.4.7 not at the current versions of the mod... but I haven't looked if the functionality was added to the top update for 1.4.7 or 1.5.X.
It is currently listed as a score of "7" (aka likely addition) on his wiki though (
http://stevescarts2.wikispaces.com/Suggested+Features) So I don't know if its even a feature yet.
And why so much drama over the new features.. Yes, you'll have to build a galgadorian cutter to have maintenance free tree farm, yes... it is very expensive, yes its a pain to make..
It is a MAINTENANCE FREE, high output do once and forget means to creatify your wood/sapling/apple supplies... a very suitable change to an extremely overpowered feature.
I just hope to see a train deployer module that will deploy/pickup X carts so you can slam it on the back of a mining cart and have it form a delivery truck back to the manager rather then having the mining cart travel back and forth.
