Scotts Lawn Fertilizer Spreader Repair

thingiverse

All this current talk about "right to repair" is great, but for something like a Scotts lawn fertilizer spreader, you can't repair something if there are no parts to purchase! In just 3 short years my "pro" edge guard spreader went from new to nuisance. The tires rotted (actually the tubes inside), the axle rusted, and it was about useless. Buy a new one? For what it is I think the price is a bit outrageous - $75. So I decided a refit with available parts and some 3D printing would get the job done. Not to mention that future repairs would be possible if any of my designs needed replacement. What you see is the final result and the assembly should be obvious. All you need for non-3D printed parts is a 5/8" shaft cut to 17" length (Amazon https://www.amazon.com/gp/product/B000H9K5PE/ -this one is 24 as I did not find an 18" one handy for sale), the two Harbor Freight tires (SKU 47638 - 8" non marring) and a few M3-15 screws to pin the center drive parts to the axle. I was going to attach the hubs to the tire rim screws using longer bolts, but the friction was more than enough to do the job. Maybe as I use this I'll make that adaptation. You would only need to do that to one of the 4 rim bolts as there is not much torque on the hub.
