This is a very heavy duty shredder/mulcher that will go through anything you want to cut with it. It requires 35-45 gpm hydraulics and weighs over 3,000 lbs so it's not built for small skidsteers. It's an absolute beast of a mower and rated for 10" trees which it walks through with ease. Clean up tree rows very quickly and leave a nice mowable surface behind you. New they are $18,500 and this unit has very low hours on it. 1" thick solid plate turntable with massive inertia to power through basically anything you want. 1/2" plate deck in all of the important places. Price is firm, if you know what it is you'll know the quality of it. Really needs an 80-120 hp machine to handle it properly. 100% US made and ready to work.
