Rated 5.0 out of 5.0 by Outstanding Shredder / Chipper If you have lots of trees and small branches and want to create your own mulch and compost this is one of the best values on the market. Powerful, heavy duty and no reason why it should not last for years with proper maintenance. I've used it for several days and no real issues. If you have two people it will go somewhat faster; one shredding and one person clearing the shute with a small rake. You can do it with one person, but will have to stop after ever 3-4 shreds to clear the shute. Not a big issue but it will slow you down. I had to clear it a few times due to putting wet material in it. It will shred it but it starts clogging up so try to let that stuff dry out in the sun for a while. It comes with ear and eye protection, extra blade for the chipper and a bag. The bag is worthless and I tossed it aside. I see people putting green material in it in videos but the manual says don't do it, let that stuff dry out. I find people often fail to read the directions on products and give products poor rating. It's a good machine and won't clog if you follow the directions and it makes great compost and mulch, very fine...pine needles, oak leaves, magnolia and pine pods no problem. I highly recommend it for a home with a lot of trees. November 17, 2014
Rated 4.0 out of 5.0 by Great Chipper! The main purpose of buying this was for the chipper. After using my neighbors Brushmaster and shopping around for quality chippers, I decided this chipper would fulfill my needs. The chipper has worked well for me so far and has helped reduce my pile of limbs and branches I had piling up. Unfortunately, I can't say the same about the leaf shredder. I still have not figured out how to shred leaves without the hopper plugging up. If I were to recommend this machine to anyone, it would be for the chipper, not necessarily for the leaf shredder.

Rated 5.0 out of 5.0 by Great chipper! I was worried at the time of purchase if this machine would do as advertised. I had a pervious large chipper that we used for cleaning mountain lots and it was very powerful. This machine does not come close to it but shouldn't it however is a great machine for all your yard work. I have used the machine for about 10 hours now and never once did it plug or have an issue. I need to replace or sharpen the blade is all now.. Great machine and one that will last a long time. September 16, 2014
