Here is my Stihl ts420 disc cutter. It's a 2020 model but not been used much at all, only used to cut openings as it'll cut completely through a 5" wall and it's a bit unwieldy! I have an electric one now to replace it so surplus to requirements. It's in good condition with a few marks commensurate with age and use. Always starts and stops no probs, runs, idles, and revs really well and I'm pretty sure I have a spare filter for it too. I have the original receipt for it in my name so you can be confident it's genuine. It's collection only from Upper Cumberworth, Huddersfield, as it's big and bulky, and I'd like to demonstrate it starts and runs fine so no postage I'm afraid.
