I have not seen any commercial shoots for the chippers you mention, but I did fashion one for my chipper using sheetmetal and 6 inch stove pipe to direct my chipped material into a garden trailer with a screened cover over the top. This enabled me to chip my material anywhere on the property and then transport it to my compost pile. Saved on my having to use shovel to load the trailer, or drag limbs etc., to the compost area. Saved a lot of excess labor on my part.

WE have a Patriot gas powered the 2nd largest model they make. We have now owned it for 8 years and the only problem we have ever had is the chute for larger branches should have some of brace at the bottom to maker it more sturdy or maybe make the whole chute out of stainless steel.Other than that it has work like a charm helping us clean up several large downed trees (weather)and other projects over the years. Troy built makes wonderful tillers my dads is now 27 years old ours is 12 never a problem with them either.Willow
