Dual 600 Manure Spreader

I'm selling my dual 600 manure spreader. We just got done using it for the year. I have the top beater for it as well, but we removed it last year. I changed it over to a 1"3/8 1000 PTO to run on my 4630. It has two aircraft tires, and 2 11Lx16's. The floor is in good shape. I did make my own paddles for it that are much more aggressive. The reason I'm selling it is I'm going to a bigger one with vertical beaters. $6,000 OBO. Feel free to call with any questions. Thanks, Josh
