Production run

Toro 21472 partsSerial 415400000–418272599

The last 21472 run naming 139-6556. In the one above it is absent and 147-8696 is named again after three runs without it — seven listings, all open.

What changes at the edges of this run

Discharge chutes

139-6556→147-8696at 418272600

This range names 139-6556 and not 147-8696. The next listing, 418272600–999999999, names 147-8696 and not 139-6556.

The listings are consecutive, so the swap is placed rather than bracketed. But 147-8696 is not new at that serial — it is listed for the three earliest runs before dropping out, and Toro states no supersession either way.

In detail

This production run

Chute Assembly 139-6556 is what Toro lists for a 21472 in this range, and this is the last run for which it does.

In the seventh and final listing, 418272600 and above, 139-6556 is not named and ASM-CHUTE, SD 147-8696 is. Those two listings are consecutive, so the swap sits at a serial we can name rather than somewhere inside a span we cannot. It is a place in the numbering, not a date — Toro attaches no dates to these runs.

The trap is in the word swap. 147-8696 is not arriving for the first time. Toro lists it for the three earliest runs of this model number, alongside 139-6556, then not for this run and the two below, and then again for the last. Reading the boundary above as “139-6556 was replaced by 147-8696” gets the direction right and the history wrong, and Toro’s pages assert no replacement in either direction.

For an owner the practical part is narrower. In this run Toro lists one chute and it is 139-6556. That it lists a different one for later machines is not a statement that yours takes the other.

If you are close to the edge

Serial numbers near a boundary

The upper edge is consecutive with the run above and therefore sharp. A serial in the last few thousand of this range still falls where Toro lists 139-6556; one digit past it and the listed chute is 147-8696.

Method

How we established this

We opened all seven of Toro’s parts listings for model 21472. The count comes from the serial-range selector the listings carry. We compared the accessories they name against the parts this site holds; 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, so this is not an exhaustive diff of the pages themselves.

The common mistake: Reading a swap at a boundary as the first appearance of the new number. On this model the incoming chute had already been listed for three earlier runs, which changes what the swap means.
