On the forestry side of things, there is already a machine called a "Feller-Buncher" - see pictures of one here:

Very few trees are cut with hand saws anymore. Feller bunchers are commonly paired with forwarders in Cut to length logging http://en.wikipedia.org/wiki/Cut-to-length_logging

The key is how to bundle the smaller stuff currently left on the forest floor...

It still doesn't help the transport side.
You can build mobile gasifiers, but they either have to go into a pipeline or GTL at the site. Gasifiers work best where you can do waste heat recovery and keep it operating for long periods of time, so going mobile isn't a great fit, unless you've got a whole lot of biomass and can operate in place for a long time.

I give the algae side of things more chance of working than the biomass.
