I have one of the above Rover 5hp shredders.
Agree with all you have said re: the limited branch sizes. Brilliant for leafy stuff and things like dried up basil bushes, etc.
Large lengths of kikuyu tend to get wrapped around the main shaft, and it is a real PITA to clean out.
Within it's limits, it is a great little machine, but I'd like to be able to mulch up 4" branches grin

This is why some people appear to be bright, until you hear them speak!
