139-6556→147-8696at 418396425
This range lists Chute Assembly 139-6556 and does not list 147-8696. The listing directly above it, 418396425–419999999, lists ASM-CHUTE, SD 147-8696 and not 139-6556.
The two listings are consecutive in Toro’s selector, so 418396425 is the edge itself rather than a bracket around it. Toro 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
The 21485’s accessory lists change once across the whole machine, and this range is where it happens.
Toro publishes five parts listings for it. Four of them carry an accessory list and each of those lists thirteen numbers. Comparing them against each other, exactly one accessory number differs: the chute. The two listings below 418396425 name Chute Assembly 139-6556 and the two above it that carry a list name ASM-CHUTE, SD 147-8696. Requesting either number as a product serves one page, for 147-8696, under the line “Replaces Product 139-6556”.
Every other accessory number holds — the same twelve on every listing that carries a list. So among the accessories Toro lists for a 21485, the chute is the only purchase the serial number decides.
That is a statement about the accessory lists and not about the machine. The listings name three different Parts Catalog form numbers between them, and the newest, for 420631776 upward, shows an assembly drawing the others do not: Quick Release Lever Assembly No. 138-3249. This site has not compared the assembly drawings, so for a part that is not in the accessory list, the serial may matter.
The lower edge of this range shows the same thing from the other side. Toro splits its listings at 415400000, and the run below this one carries the same thirteen accessories, number for number. That split is real in Toro’s catalogue and changes nothing in the accessory list. One of this range’s two edges matters there and the other does not.
One listing, 420000000–420631775, carries no accessory list at all. It is recorded as a page that was opened and nothing is scoped to it, because a page that lists nothing is not a page that lists an absence.

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 21485, serial range 415400000–418396424; that listing shows 139-6556 instead.
If you are close to the edge
Serial numbers near a boundary
The edge that matters is the upper one. A serial at 418396424 is in this range, where Toro lists 139-6556; one digit higher and the listing shows 147-8696. Toro says the newer number replaces the older, so a reader on the earlier side is being pointed somewhere rather than left with a number that stopped appearing.

Method
How we established this
We opened all five listings Toro publishes for model 21485 and compared every accessory list in full against every other, which is practical on this machine because four carry a list and each lists thirteen numbers. The product pages for both chute numbers were opened as well. 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: Assuming a machine with five published serial ranges must have several accessory changes across them. This one’s accessory lists have a single change, and knowing that is worth as much as knowing where it is.

This listing carries no accessory list at all. What it does carry is seven of Toro’s assembly drawings — Deck Decal, Engine and Blade, Front Wheel and Height-of-Cut, Handle, Housing, Rear Bag, and Rear Wheel and Height-of-Cut — and the usual Parts & Manuals section. Recorded as a source so the range is accounted for, and scoped to no fitments: a page that lists nothing is not a page that lists an absence.

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.
