I believe it would be the RBX series of CIH and the BR series of NH. it was the 1st plastic shrouded balers so they are easy to spot. They are built off the NH Baler.
BR7070 should be the new Holland #.
The 600 series NH had a Case version that was very similar. Sheet metal was a little different but the main frame and inner working were extremely similar between the two. I'm not sure on the 4x6 but I know on our 660/664 we get A LOT of parts from case as they are closer. |
