Toro 21472 partsSerial 418272600–999999999
The last of the 21472's seven listings, all open, and the only one naming 147-8696 without 139-6556 — though 147-8696 is on the first three runs too.

This range names 147-8696 and not 139-6556. The listing directly below, consecutive with this one, names 139-6556 and not 147-8696.
A reader arriving with 139-6556 on the machine needs to know this is where Toro stops listing it — and that the number listed in its place is one Toro also lists for the three earliest runs of this model.
In detail
This production run
This is the last of the 21472's seven runs by serial number, and the discharge chute Toro lists for it is ASM-CHUTE, SD, 147-8696. Chute Assembly 139-6556, which is listed for all six runs below it, is not here.
The listing directly below is consecutive with this one, so the boundary sits at a serial we can name rather than inside a span of runs we have not read. That is a position in Toro's numbering and not a date; the pages carry none.
What the boundary does not mean is that 147-8696 is a newer part. Toro lists it for the three earliest runs of this model number, beside 139-6556; it is then absent from the listings for three runs, and it is present again here. Across the seven listings the two chutes trade places rather than one replacing the other. Toro’s pages give the order of the runs and nothing else — no dates, no ages, and no statement that either number supersedes the other.
There is a practical consequence. If you were told that the SD chute is the current part and the other the superseded one, that is a reasonable thing to conclude from the two ends of the catalogue and it does not survive the middle. Toro lists 139-6556 for six of the seven runs.
Absence is still only absence. This page does not say 139-6556 stops fitting.

Discharge chutes
ASM-CHUTE, SD 147-8696
Listed by Toro as ASM-CHUTE, SD on its official parts page for model 21472, serial range 418272600–999999999. It is the only chute on that listing.
Not listed here
Listed for a neighbouring run, but not this one
Absence from a parts listing is not a statement that a part does not fit. It is the manufacturer not saying.
139-6556 Not verified

If you are close to the edge
Serial numbers near a boundary
The lower edge is the sharp one and the run below it is consecutive. This range has no upper edge — it runs to the top of Toro’s published serials for the model — so nothing above it is unread.

Toro publishes 7 parts listings for this model number. We have opened 7.
Method
How we established this
We opened all seven of Toro’s parts listings for model 21472, the count taken from the serial-range selector the listings carry, and compared the accessories they name within the part categories this site records. Engine oils, a bag, a striping kit and fuel products other than 130-2393 appear on the pages and we hold no record for them. A part absent from a listing is recorded as unknown rather than incompatible.
The common mistake: Taking the last listing as proof of which part superseded which. Toro’s selector gives an order of serial ranges and nothing else — no supersession, no dates — and on this model the number in the last listing is also in the first three.
