Nope I sure don't, the guy's here on the site kind of talked me out of it being it was so small (if you look on page 12 of the attachments section under my name you will see the thread, I don't have a clue on how to hook it here) I did call them, being there made just up the road from me here in Florida and the gal who answered the phone is the wife of the fellow that makes them very nice and easy to speek with. I tried to talk he into making me a bigger one.
Deponding on how your collect you manure it could work for you....I stock pile it in 10x10 bins and compost it before spreading and with it being small it would take forever to spread out a 10x10 bin 5' to 6' deep. If you go straight from the stall to the field you maybe ok with something that small and if I remember right you can get that spreader with bar tires as an option. She also told me it will work with either sawdust or straw bedding
