This is a PTO tractor drive wood chipper. It will handle up to 6-7” limbs. Used it jut today to finish up a project. It took what would have been at least 4 trailer Loads of brush and limbs and it all fit in one load and the majority of the space on the trailer was used up with root balls from the trees we pulled up. It is fast and efficient. It can save you a lot of time and hard work. $2850
