The Challenger RoGator 645B falls in the middle of the challenger range of self-propelled sprayers between the RoGator 635B and the RoGator 655B.

All the machines are big sprayers and not all that common on this island. The 645 which I went to look at was a demonstrator unit from WBD machinery in north Dublin. Unfortunately the day I went to see this machine was not a spraying day so only a static viewing was possible.
