"Bought my Great Plains 1205NT three years ago. It had been abused by the previous owner. I had to rebuild the whole bottom end and fix some holes in the grain box. Small seed box and all the working parts had been trashed, so I didn't even try to repair. I plan on fixing it later. I grow soybeans and wheat, so it works great for what I do. The 12ˈ is a perfect fit for my John Deere 4230. The Great Plains 1205NT is easy to use and affordable to repair. Thanks for a great product."
