I paged through their catalog online, some things I'd def like to try out. One thing I noticed from the catalog, I'd love to see the GreenMech chippers advertised on the back cover available in the US. I think they'd be the bees knees for a trim arborist, the small safetrak 16-23 model is only 73 cm wide, it'll fit through most gates. Another feature on some of their chippers is a swivel platform. Sounds awesome to me, able to swivel the entire machine so you can load perpendicular to the street from the yard, rather than having to load from the street.
