139-6556→147-8696at 418280833
Toro lists 139-6556 for the 415500000–418280832 range and 147-8696 for this one.
The two listings are consecutive in Toro’s own range list, so the change falls at 418280833 rather than somewhere inside a span.
In detail
This production run
Toro publishes eight parts listings for the 21464 and all eight have been opened. The blade 59534P and the Briggs & Stratton EXi maintenance kit 130-8148 appear in every one, unchanged. The discharge chute does not: 139-6556 runs through the first seven listings and stops, and this range is the only one carrying 147-8696.
Those two numbers are one part. Requesting either as a product serves the same page — 147-8696 — above the line "Replaces Product 139-6556". Toro states that on the product side and on none of the eight listings, which is where somebody buying a chute would be looking.
One other thing moves on this machine, and we do not think it is about the machine. Ten items — a snow blower, a leaf blower, a string trimmer, a hedge trimmer, a chainsaw, three batteries, a charger and the Smart Stow Cover — appear together in the three listings from 411986087 to 418280832 and in no other range. Ten unrelated things do not join a mower's fitment at once and then leave it. We record what Toro lists, and we are not going to tell you the cover stopped fitting.

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
Toro does not list chute 139-6556 on its parts page for model 21464, serial range 418280833–999999999; that listing shows 147-8696 instead.
490-2012 Not verified
Toro does not list the Smart Stow Cover on its parts page for model 21464, serial range 418280833–999999999. This row states only what this listing shows. Whether that absence means anything is a question about the machine as a whole, and it is answered in the serial-range note, which cites the listings that establish it.
If you are close to the edge
Serial numbers near a boundary
Serial numbers just below 418280833 fall in the previous range, where Toro lists 139-6556. If your serial is near that edge, read the plate rather than the model number — both ranges are the same 21464.

Method
How we established this
All eight of Toro’s parts listings for model 21464 were opened, following the serial-range selector on the listings themselves, and their accessory lists compared within the part categories this site records. 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. Parts present in one listing and absent from another are recorded as unknown rather than incompatible.
The common mistake: Ordering 139-6556 because seven of the eight listings for this model number show it. Seven out of eight is not the same as yours; the serial is what decides.

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.
