Yep ,I got a biggish tractor and a 7ft wide "slasher"they call em here.....Getting pretty rusty after 40 yr out in the weather ,but still works good.Blades are solid steel 3/4" thick ,lots of weight if they get loose too....Bolts are about 1/2 way thru ,must replace them when I think of it.One time the slasher threw a lump of wood ,round and smooth like a football ,was going straight for the big front window on the house over the road.....turned aside at the last few bumps ,and hit the brick wall.....the people were watching ,and poured out like angry wasps....I pretended I didnt see it ......serves em right for complaining to the council about my back paddock.
