My Mom is trying to sort through all of my late Stepfather's tools and equipment to see what she needs to keep and what to sell. She wants to know the year/value of a Stihl weedeater model FS 55 RZ serial number 4140-011-2322.

I have that model, it's a 1999.

Check Craigslist for comparison. Only use Stihl trimmer or weed eater for search terms. Seems to be a 2017. Even if not running I would not sell a Stihl anything if I had a yard.

I don't have an answer but do have a question. We inherited this same weed eater from my Dad. We need a replacement for the head sleeve. When I search online, the pictures that come up, as available to purchase, look like the depth is twice the size that we need. We even tried a Stihl dealer and had no luck. Do any of you know where we could find one tiny head sleeve to purchase?

Mandy,
I'm not sure of the year of your trimmer but that model in good running condition should sell for around 100 dollars.
