DIY Shredder

So I’ve been slowly working at getting rid of my 30ft Bradford Pear tree in the front yard. After I drop a couple limbs I cut all the smallest branches off and make a pile of them. I then use my old gas mower and slowly lower it on to the pile of sticks and it does a pretty good job at shredding all the leaves and sticks as well as spreading the discharge out over a decently wide area.
