I am very interested to see that the Rover HD self-propelled slasher was in existence a lot earlier than I had thought. The height adjustment is missing off mine and has holes bored in the axle supports to allow for the height to be adjusted by moving the wheel up and down according to the holes. I mistakenly believed that someone must have broken the lever at some point, but could not see any sign of where it had been attached. I also asked the former owner and he shrugged when I mentioned a height lever. He told me if you want to adjust the height you have to take off the front wheels and put them in a lower or higher hole. I had also incorrectly assumed that the HD was strictly a 1970s machine. It appears the prototype was in existence a decade earlier. This forerunner must have dated from the early 1960s and was painted yellow, not royal blue. It was missing the height adjustment lever, which would be added to later models, and it was also apparently missing any belt guards. Mine has exactly the same rudimentary belt guard on the front pulley as the one shown on the history page. This shows a HD in action in Vietnam in the early to mid-1960s. I learn something new every day. I am now thinking I will not ruin what is obviously an early model HD by adding guard covers that were probably never on there to begin with. I will leave it the way it is. See:
