This is a Ryobi split shaft system, which can take a variety of utensils: strimmer, hedgecutter, tiller, etc.
I've only found a strimmer head and that's not all there.
Last time I used it, it stopped and wouldn't re-start. It's been kicking around now for a few years waiting for me to have another look at it...
Tell me why you want it: I'll give it to the person who makes the best case.
Ryobi petrol strimmer, not working. (Burley LS4)
