Short answer

What we have verified
What decides it
The numbers that matter here
- Your serial range
20122P for 400000000–402081999, 402082000–403599999 and 414709996–999999999; 20120P for 407700000–410243166
This is the whole decision, and the answer is not monotonic — the later blade is not simply the newer one.
- The two numbers look alike
20122P is hi-lift; 20120P is Atomic
Same stated length, same machine, two digits apart. Matching on "15.4 inch TimeMaster blade" will not separate them.
- Blade count
20120P’s page states two, re-checked 5 September 2026; 20122P’s states none
Toro calls both parts kits and, as of 5 September 2026, states a count for only one of them. If your serial calls for 20120P, Toro tells you the kit is two blades; for 20122P it still does not say, so ask the seller before assuming one purchase does both spindles.
- Ranges we have not opened
All eleven of Toro’s listings are open; ten carry an accessory list
If your serial number is outside the four we checked, go to Toro’s listing for your own range rather than reading across from this page.
In detail
Choosing mower blades for this mower
This is the page that should stop you using "mine is a newer machine" as a shortcut.
Across the ten 21199 listings that carry an accessory list, the blade number goes 20122P for two runs, 20120P for four, then 20122P for the last four. It leaves and it comes back, and the middle stretch is long enough to be a period rather than an oddity.
This site said the Atomic blade was on a single range until 21 August. It had opened the first, second, sixth and eleventh listings — one of which happened to be Atomic — and read one run where there are four. If your serial falls anywhere from 403600000 to 410243166, the Atomic blade is what Toro lists for your machine, and the odds of that are far higher than the old page implied. Toro lists 20122P — the 15.4 Inch Hi-Lift Replacement Blade Kit — for 400000000–402081999, for 402082000–403599999, and for the latest published range, 414709996–999999999. In between, the 407700000–410243166 listing shows 20120P, the 15.4 Inch Atomic Blade, and does not show 20122P at all.
We do not know why, and Toro does not say. The pages show which blade is listed against which serial range and nothing more. What we can tell you is that no rule of the form "later machines take X" survives this data, and neither does matching on the description: both blades are 15.4 in., both are for a TimeMaster, and two digits separate the numbers.
Also worth checking before you buy: **the two numbers do not publish the same way.** Toro calls 20122P a "Blade Kit" and designates 20120P KIT-BLADE, TIMEMASTER, 30IN, and a 30 in. deck carries two spindles. Between 31 August and 5 September 2026 this page said neither product page states a quantity; re-opened again on 5 September, 20120P's page now carries a bullet reading "Includes 2 blades which each measure 15.4"", while 20122P's page still states none. So if your serial calls for the Atomic blade, Toro tells you the kit is two; if it calls for the hi-lift kit, Toro does not say, and you should ask the seller before assuming one purchase does both spindles. Toro does say it elsewhere when it chooses to — the 22 in. blade 59534P’s page says it is sold individually.
We opened all eleven listings Toro publishes for this model number.
The mistake we see most
Method
How we established this
We opened Toro’s parts listings for model 21199 under serial ranges 400000000–402081999, 402082000–403599999, 407700000–410243166 and 414709996–999999999, and recorded the blade shown in each. The count of eleven ranges is read off the range selector on those pages. Where a blade is absent from a range’s listing we record the fitment as unknown rather than incompatible, because absence from a parts page is not a statement that a part does not fit. Both blade product pages were re-opened on 5 September 2026.

Earliest of the four ranges we opened. Lists 130-8149 (BRIGGS MAINT KIT - TM 17 & NEWER) and 20122P (15.4 Inch Hi-Lift Replacement Blade Kit (TimeMaster)). The range selector names ten further ranges for this model number.

One range later. The maintenance kit is 130-8146 (Engine Maintenance Kit for Walk-Behind Power Mower) where the preceding range listed 130-8149. Blade 20122P is unchanged.

The latest published range. Still no maintenance kit. Blade 20122P is listed again, and 20120P is not — so across the four ranges we opened the blade number does not move in one direction.

15.4 Inch Atomic Blade (Part # 20120P)
The Toro Company · Primary source · Accessed September 5, 2026
Read three times, and the third reading no longer agrees with the second. **21 August 2026:** recorded as giving Toro’s internal name KIT-BLADE, TIMEMASTER, 30IN and as stating that the kit includes two blades each measuring 15.4 in. **31 August 2026, re-opened:** the internal name is still KIT-BLADE, TIMEMASTER, 30IN, and the page carried no statement of quantity and no measurement anywhere in its body — the 15.4 in. appeared only in the product name — across seven bullets read as four. That reading matched the Wayback Machine’s only capture of this page, from 6 September 2025, and the two together were taken as settling the question against the 21 August reading. **5 September 2026, re-opened again, independently, twice:** the page now carries seven feature bullets, not four, and the fifth reads verbatim “Includes 2 blades which each measure 15.4"”. Everything else holds — same title, same internal designation, no redirect, no supersession line. **The page changed between 31 August and 5 September 2026**, most likely by Toro adding bullets rather than by either the archive capture or the 31 August reading missing one: the 31 August reading and the archive agreed on a shorter, four-bullet page, and the current page has three more bullets than either recorded, not merely one overlooked. What Toro publishes as of today states the blade count; the notes and specifications that carried “no quantity” have been corrected to match. See review/2026-09-05-section-l-review.md.

15.4 Inch Hi-Lift Replacement Blade Kit (TimeMaster) (Part # 20122P)
The Toro Company · Primary source · Accessed August 21, 2026
Toro’s product page for the hi-lift kit, served directly at this number with no redirect and carrying no supersession line. It states no quantity, no measurement of any kind and no instruction to verify a serial number. It does carry an overview: a steel replacement blade, described as cutting finer for easier mulching and bagging, and as designed for cut quality and durability. None of that names a machine, a model or a deck size. Recorded because a record on this site attributed a two-blade statement to this page, and the statement is on 20120P’s page instead.

15.4 Inch Atomic Blade (Part # 20120P), archived capture of 6 September 2025
The Toro Company, via the Internet Archive · Primary source · Accessed August 31, 2026
The only capture the Wayback Machine holds of this page, taken eleven months before this site first read it. **As of 31 August 2026 it matched the live page and settled the two-blade question against the 21 August reading.** The captured page carried the same title, the same internal designation KIT-BLADE, TIMEMASTER, 30IN, the same four bullets and the same overview as the page served on 31 August 2026, and like it **stated no quantity and no measurement anywhere in its body**. The only substantive difference between the 2025 capture and the 31 August 2026 page was the price. **That is no longer the state of the live page.** Re-opened on 5 September 2026 (see `src_toro_product_20120p`), the live page now carries seven bullets rather than four, including one stating the kit holds two blades. This archived capture still accurately records what the Wayback Machine holds for 6 September 2025 and what the live page said as recently as 31 August 2026 — it is the live page that has since moved, not this record. Recorded as its own source because a claim about what a page used to say needs a record of the page as it used to be.
