The design is quite simple with one wheel driving a bevel gear in a gear box. If the wheel turns the axle shaft and the center pin in the spreader with the retainer/cotter pin does not turn it is likely something has failed in the gear box.

If both wheel spins and the axle does not turn than the drive wheel has disengaged the axle shaft and the cotter pin in the drive wheel needs to be replaced.

The compounds used in the spreaders are corrosive. Usually the gears and axle become bound due to corrosion. By oiling the bearings and wiggling the wheels they will free up,

Hope this helps?.

I am sorry to hear about the problem with your spreader. Sometimes we have replacement parts for our spreaders. Please give Scotts a call at 877-465-5160 at your earliest convenience to check part availability. Hilary @Scotts

I found drop-rate tables at http://www.vigoro.com/ProductCategories/WeedInsectControl/SummerFertilizer/ProductDetails/Spreader+Settings.htm and http://www.bayeradvanced.com/media/productlabel/502840A_label.pdf. I don't know how accurate they are, but they are consistent with one another so I'm using them :)

Its probably bent or broken one of the tie ends on the steering. Ring your nearest suppier they will pick it up and repair it.

If the wheels turn( that is you can push the spreader easily) but the vertical shaft that spins the broadcasting plate doesn't, seems like the gears connecting the axle to that vertical shaft are worn; but if the wheels just slide along the gropund without turning then it would seem something right under the bin is keeping the verical shaft from turning. But I'm NOT an expert; I'm looking for an answer myself,
