Ok, for the last two years we have just used our lesco broadcast spreader that we walk and a ag-fab pull behind that went behind our mower. I now have a 4400 John Deere tractor with a 3 point. I have seen these spreaders that are cone shaped that hold about 750 lbs. Do I want one of these? We have 12 properties that are over 100K sq. ft. How well do they work. I would like your opinions. Hope I was clear enough. If not let me know and I'll try and help.
