139-6556→147-8696at 418280833
This range lists Chute Assembly 139-6556 and does not list 147-8696. The listing directly above it, 418280833–999999999, lists ASM-CHUTE, SD 147-8696 and not 139-6556.
The two listings are consecutive in Toro’s selector, so 418280833 is the edge itself. Toro also states the relationship: requesting either number as a product serves one page, for 147-8696, under the line “Replaces Product 139-6556”.
In detail
This production run
Every 21464 run below 418280833 is listed with Chute Assembly 139-6556, and this is the last of them. Seven ranges carry that number and the eighth carries ASM-CHUTE, SD 147-8696 instead. Requesting either number as a product serves one page, for 147-8696, under the line “Replaces Product 139-6556”, so this is a supersession Toro states rather than a substitution a reader has to work out.
More than the chute stops being listed at the same serial, and it is worth saying why this page does not treat the rest as a second boundary. This range names twenty-two accessories and the one above it names twelve. Ten other numbers leave together: the Smart Stow Cover 490-2012 and nine separate products — a snow blower, a leaf blower, a string trimmer, a hedge trimmer, a chainsaw, three batteries and a charger. All ten are also absent from the four earliest runs of this machine, appearing only from 411986087. A block that is missing, then present for three runs, then missing again reads as a catalogue change rather than a change to the mower, and this site records where the cover is listed without claiming a boundary either time.
That distinction is the whole difference between the two. The chute number moves once, in one direction, and Toro states that the new number replaces the old. The cover moves twice, in a block of ten.
So for a 21464 in this range Toro lists 139-6556 as the chute, and for the serial above it a number Toro says replaces it. If your machine is near the top of this range, the digit matters and the plate is the only place to read it.

Absence from a parts listing is not a statement that a part does not fit. It is the manufacturer not saying.
147-8696 Not verified
Toro does not list chute 147-8696 on its parts page for model 21464, serial range 415500000–418280832; that listing shows 139-6556 instead.
If you are close to the edge
Serial numbers near a boundary
A serial at 418280832 is in this range, where Toro lists 139-6556. One digit higher and the listing shows 147-8696 instead. Because Toro states that the newer number replaces the older, a reader on the wrong side of this edge is being pointed somewhere rather than left without a part.

Method
How we established this
We opened all eight listings Toro publishes for model 21464 and compared this range against both neighbours in full, then opened the product pages for both chute numbers. The pages also carry accessories this site holds no record for, so this is a comparison within the categories it records rather than an exhaustive diff of what they list.
The common mistake: Reading everything that stops appearing at a serial as part of the same change. Eleven numbers leave this listing at 418280833 and only the chute is a boundary; the other ten were missing from the machine’s four earliest runs as well.

ASM-CHUTE, SD (Part # 147-8696) — reached from /product/139-6556
The Toro Company · Primary source · Accessed August 31, 2026
Requesting the 139-6556 product URL answers 200 with no redirect and serves a page titled ASM-CHUTE, SD under part number 147-8696, carrying the line “Replaces Product 139-6556.” It describes neither chute — no discharge type, no machine application. This is Toro stating the supersession between the two numbers directly, which seven pages on this site said it did not state. **Re-read 31 August 2026 and unchanged in every particular**, including the supersession line, the absence of any description and the serial field reading None-None.

ASM-CHUTE, SD (Part # 147-8696)
The Toro Company · Primary source · Accessed August 31, 2026
Toro’s product page for the SD chute, served directly at this number with no redirect. It carries the same line, “Replaces Product 139-6556.” It gives no discharge type and names no machine, so what the chute is and what it fits are still not published anywhere we have found — only the relationship between the two numbers is.
