Production run

Toro 21200 partsSerial 405700000–407799999

The 21200 run where hi-lift blade 20122P returns after two runs of Atomic. It is named in every run above this one. All eleven listings are open.

What changes at the edges of this run

Mower blades

20120P→20122Pat 405700000

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

This is where the blade goes back, and it stays back. Every run above this one names the hi-lift, which makes the Atomic a two-run interruption rather than a direction of travel.

In detail

This production run

The 21200's blade comes back to hi-lift 20122P here and never changes again.

The run directly below names the Atomic 20120P, and the one below that does too. Below those, the two earliest runs name the hi-lift. So the Atomic blade occupies exactly two of the eleven listings Toro publishes, and this is the run that ends it.

Because the two listings either side are consecutive in Toro's selector, 405700000 is the serial itself.

A part number that returns is the finding this route family exists for. Read only the earliest and latest listings for this model and the blade looks unchanged; read only the middle and the Atomic looks current. Both are wrong, and only opening every run shows it. The 21199 does the same thing across four runs rather than two.

No engine maintenance kit is named for this range, and none for any run above 403599999. That is recorded as unknown, not as a statement that none is needed.

Serial numbers near a boundary

The lower edge is sharp and the run below it is consecutive. A serial just under 405700000 falls where Toro names the Atomic blade instead.

Method

How we established this

We opened all eleven listings Toro publishes for model 21200, a count taken from the serial-range selector the pages carry, and compared the accessories they name against the parts this site holds. Ten carry an accessory list; 413000000–414514168 carries none and nothing is scoped to it. Engine oils, a bag, a striping kit and fuel products other than 130-2393 appear and we hold no record for them.

The common mistake: Assuming a part number only ever moves forward. On both TimeMasters it moves back, and the run it moves back at differs between them.
