Someone gave it to me and I've never had it running but it feels like the engine's got good compression when I pull on the rope. Nothing seems froze up. I'm sure it will need a fuel filter and new fuel hose kit, spark plug and a new pull rope probably wouldn't hurt. Then I think it will work good for tilling in some fresh compost and probably a little cultivation too.
Hmmm. Never looked it up until just now. - There are not too many things a STIHL YARD BOSS® can’t handle. A great multitask yard care system, the lightweight and powerful MM 55 CE STIHL Home Scaper Series ™ YARDBOSS® offers the same ability as the MM 55 to quickly convert from a minicultivator to an aerator, sweeper, dethatcher and more
Convert to a sweeper? Mine's the older MM 55 they reference. I must go research now.
