I bought this thing a few years ago, but never really used it much. Now that I have a ZTR with a collectoni system, we never even use it at all. thus it has very low hours, maybe 20 hours max. Its 6.5 horse power, self propelled and has a 10:1 reduction ratio. It actually does work pretty good, especially for cleaning along curbs and other tight spaces. Plus it does a really good job of shredding the leaves, they are like saw-dust when you empty the bag. It can also chip/shred sticks and branches that are up to 3" in diameter. $450.00 and its yours. PM if interesed.
