I have an old Roper 21" (AYP) rear tine roto-tiller that I use for weeding between rows . The tines have become so worn out that it just not doing the job anymore . I found the equivalent Husqavarna (AYP) parts diagram , and they are still available at $25 US plus

$ ect. . Not in the budget when needing 16 of them . I shopped around for tines and found aftermarket tines to fit a Toro on Evel Bay that the measurement suggested would work . At less than $120

all in with hardware I pulled the trigger . I am happy to say they fit and are working great .

- difference between new and old tines
I think I got my $$ worth out of the old ones .
