Seller mowerfreedom is based in Marion, S.D. and is parting out at least one 1816B. I would call there to see if they can help you with the ROPS. These were great little barn machines, and many of them wound up in the northern Midwest.I've had two 1816s, and I have one now. I had to replace the cage a few years back when a tree fell on the machine. It hit so hard it collapsed the tires and flattened the wheels. No one was in the machine at the time, but I think we would have survived. It was a 30-32" tree, 90' tall. There are 1816s all over eBay. The most prolific sellers are in your state, or next to it. They post machines all the time. One is, I think, Doug's Closet. I bought counterweights and an axle from him. You can also try Wenger's of Myerstown in Pennsylvania. I bought one of my machines from them before I figured out I could fix the one that was crushed. Wenger's buys machines from estate sales and barn fires, and disassembles them and catalogs the parts. They like the bigger skidsteers and farm tractors, but they will have the occasional little machine. The next interesting parts machine I sell, I'll post here.
It's Dakota Outdoor Power. If you look at the 1816 loader arms they have for sale, you can see the cage in the background, taken off the machine. I guarantee at least that they used to have one for sale.Seller mowerfreedom is based in Marion, S.D. and is parting out at least one 1816B.
