text: What a complete piece of trash. The entire design is flawed. I finally decided to upgrade from my old Scotts spreader. I treated myself to something much more expensive. It broke within 30 minutes the first time I took it out of the box. Any sort of clumps will jam it up. If you are putting any force on the unit it will snap the main driver. By the way the main driver is a cheap piece of plastic with tiny gears. I spent 40 dollars to replace the broken parts and took the spreader out again being careful to sift through the fertilizer to make sure that there were no clumps. Guess what? Same result. The driver snapped again. The only thing I can think of is it snapped under the weight of the product in the hopper. The tires are a nice feature. I guess I am going to put them on my old Scotts spreader. It does not work for intended purpose. Find something else.
