20120P→20122Pby 414709996
This listing shows hi-lift 20122P. The previous listing we opened shows Atomic 20120P and not 20122P.
Four listings we have not opened sit between the two, so 20122P had returned by this serial rather than at it.
Toro publishes listings between the two we opened that we have not read, so the change happened at or before this serial rather than exactly on it.
In detail
This production run
The blade on this model number does not move in one direction. Toro lists the 15.4 Inch Hi-Lift Replacement Blade Kit (TimeMaster), 20122P, for the two earliest runs we opened, the 15.4 Inch Atomic Blade 20120P for the 407700000–410243166 run, and 20122P again here.
That is worth knowing before buying from a listing that quotes a serial range without saying which one. An offer of 20120P "for the TimeMaster" matches one of the four runs we opened and not the other three.
Four unread listings sit between this range and the previous one we opened, so 20122P had returned by 414709996. We cannot say which run brought it back.
No engine maintenance kit appears in this listing either — neither 130-8149 nor 130-8146. That has now been true of both of the two latest runs we opened.

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

Serial numbers near a boundary
This is the last range Toro publishes for the model, so there is no later listing to cross into. The uncertainty sits on the other side: the four runs between this one and 407700000 are unopened.
Other runs
Other production runs of the 21199
Toro publishes 11 parts listings for this model number. We have opened 4.
Method
How we established this
We compared this listing against the three earlier 21199 listings we opened, tracking the blade and the maintenance kit across all four.
The common mistake: Buying a blade from a listing that names the TimeMaster but no serial range. This model number uses two blade numbers across the runs we opened.

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.
