I’ve been using my PT12 for over six years now and it has earned its keep and cost. I use it to create mulch and chips for my yard, which has quite a few trees and natural areas that create plenty of branches and leaves. I originally bought a cheaper and smaller chipper from another company and realized immediately that I needed more machine. The PT12 has been reliable and starts up practically every time on the first or second pull. However, one has to avoid putting fresh vines into the machine, since they tend to wrap around the shaft and not shred; if this happens the PT12 is practically designed to permit me to easily service it. It’s user friendly and one of the best moves I’ve made, tool wise. It’s surprisingly maneuverable for a four wheel vehicle; just make sure you have an area to store it.
