Affirmative, use the best tools for your context, especially when those tools were used to destroy the natural system that used to be there. (My land was filled with stone and gravel with 4-6 inches of soil ontop using machines...) Use any means nessasary to move the current system into one that will self-renew and self replicate. That's permaculture. Set into motion a permanent self-renewing system!
