I went down a rabbit hole last night and basically no companies in America currently make or sell biomass harvesters (forestry mulcher integrated with a capture system), which is a shame for gasification and biochar production.

Basically the closest thing I could find today are models like this with a grapple integrated into a chipper and storage unit, but a system like this would still require another machine for actually harvesting biomass and likely makes using actual forest waste not possible.

Here is the ideal model for integrated wood chip harvesting for gasification and biochar production but it appears it's out of production.
