Toro 21199 partsSerial 402082000–403599999

The only one of the 21199's eleven listings, all now open, that names kit 130-8146. The run below names 130-8149; no run above names a kit at all.

What changes at the edges of this run

Engine maintenance kits

130-8149→130-8146at 402082000

Coming into this range the kit Toro names changes from 130-8149 to 130-8146.

The two listings either side are consecutive in Toro’s list, so this serial is where the listing changes and not merely where we can see that it has.

Mower blades

20122P→20120Pat 403600000

This range names hi-lift blade 20122P. The listing directly above it, consecutive with this one, names Atomic blade 20120P and not 20122P.

This is the serial at which the listed blade changes. It changes back four runs later, so a reader who assumes the newer number is the final one will be wrong.

Engine maintenance kits

130-8146→—at 403600000

Kit 130-8146 is named here and in no listing above. No run above this one names any engine maintenance kit at all.

Whether Toro considers this kit replaced by something is not on these pages either way. What they show is the number leaving the listing with no other kit number appearing.

In detail

This production run

This is the run where the most changes at once on a 21199, and every edge of it is a serial we can name rather than a span we cannot.

Coming in, at 402082000, the engine maintenance kit Toro names changes from 130-8149 to 130-8146. Toro describes the second as the Engine Maintenance Kit for Walk-Behind Power Mower, without the TimeMaster reference the first carries in its name. Neither listing gives contents. Away from the listings the two differ: the product URL for 130-8146 serves a replacement part, 20301, whose page itemizes it, while the URL for 130-8149 redirects to Toro’s page-not-found. So one has published contents under another number and the other has none we have found.

Going out, at 403600000, two things happen together. The hi-lift blade 20122P gives way to the Atomic blade 20120P. And the maintenance kit stops being listed — not replaced by another number, simply absent, and absent from every one of the six runs above this one.

That second point is the one worth carrying away. This is the last 21199 listing that names an engine maintenance kit at all. Toro dropping it from a listing is a statement about what it sells for those runs, not about what the engine needs, and this site records the later runs as unknown rather than as having no kit.

Absence from a parts listing is not a statement that a part does not fit. It is the manufacturer not saying.

If you are close to the edge

Serial numbers near a boundary

Both edges are sharp, and the listings either side of each are consecutive. A serial near 402082000 decides which kit number the listing shows; a serial near 403600000 decides both the blade number and whether a kit is listed at all.

Method

How we established this

We opened all eleven listings Toro publishes for model 21199 — the count comes from the serial-range selector the listings carry — and compared the accessories they name against the parts this site holds. Ten carry an accessory list; 413000000–414709995 carries none, so nothing is scoped to it. 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 the blade change at 403600000 as the last word on which blade this machine takes. It changes back at 410243167, and only the runs in between show it.

Engine Maintenance Kit for Walk-Behind Power Mower (Part # 20301) — reached from /product/130-8146
The Toro Company · Primary source · Accessed August 31, 2026
Requesting the 130-8146 product URL serves the product page for 20301 and carries the line “Replaces Product 130-8146”. That page itemizes the kit: a replacement air filter (130-8163), a replacement spark plug (77-7330), an 18 oz. bottle of Toro SAE 30 walk-behind power mower engine oil (38916) and two packets of fuel treatment (130-2393). The itemization is published for 20301, not for 130-8146. **Re-read 31 August 2026, unchanged, and it publishes a condition this record had not held:** the kit is stated to be for Toro walk power mowers with **Briggs & Stratton 875/1000 Series engines**, and its internal designation reads MAINT KIT BRIGGS 875/1000 SERIES. Worth reading beside 130-8148, whose replacement page states a different engine family entirely — EXi 163cc — so the two kit numbers on the TimeMasters are not two labels for one thing.

No product page at /product/130-8149
The Toro Company · Primary source · Accessed August 31, 2026
Requesting this product URL redirects to /en/page-not-found, which serves Toro’s “We were unable to find the web page you requested” page and answers HTTP 200 — not a 404, as this record and two notes said until an independent review checked the status code rather than the wording. Recorded so that “we found no contents for this kit” names a page that was actually opened, rather than standing on the parts listings alone. **Re-read 31 August 2026: the redirect and the wording are unchanged, and the page’s own heading reads “Page Not Found (404 error)”** — which is exactly how the original mistake was made. The page says 404 and the server does not.
