Bosch F016T47920 — genuine Bosch replacement scarifier spring tine (claw). A single heavy-duty spring tine designed to clip into a scarifier/dethatcher cassette and pull up thatch and moss with reliable spring action. — heat-treated spring steel profile with the retention foot that fits cassette carriers used on many lawn-rake/scarifier heads.

Fits a range of scarifier and lawn-rake cassettes from the Qualcast / Atco / Allett — for example Qualcast RE25, RE30 and RE35 series and Concorde/XR/Classic cassette models, plus Allett C‑20, C‑24 and C‑34 cartridge cassettes and the 14", 17" and 20" scarifier cassettes used across those lines. If your scarifier cassette uses individual spring tines of the common stamped/claw style, this F016T47920 part is the direct replacement used in those assemblies.

Simple to swap: the part installs by sliding the retention foot into the cassette carrier slot and hooking the tine so it springs outward under load — replacing worn or broken tines restores cutting/raking performance without needing to replace the whole cassette. Individual pieces are commonly sold so you can replace only the damaged tines and get the unit back to work quickly.

If you need confirmation that this matches the worn part on your cassette, compare the stamped spring foot and claw profile to your existing tine — the F016T47920 is the industry standard replacement for the models listed above.
