Production run

Toro 21199 partsSerial 403600000–404319999

The first 21199 run naming Atomic blade 20120P, and the first naming no engine maintenance kit. All eleven listings are open; both changes land here.

At your boundary

What changes at the edges of this run

Mower blades

20122P→20120Pat 403600000

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

It is the first of four consecutive runs naming the Atomic blade, and the hi-lift is named again from 410243167. Toro’s listings show the order the numbers appear in and say nothing about how the two parts relate.

Engine maintenance kits

130-8146→—at 403600000

No engine maintenance kit is named here. The listing directly below names 130-8146.

No run above this one names a kit either, so this serial is where Toro stops publishing one for the machine. No other kit number appears above it.

In detail

This production run

Two things change on the 21199 at this serial, and both of them are visible only because the run below and this one are consecutive in Toro's selector.

The blade Toro names becomes the 15.4 Inch Atomic Blade, 20120P, where the run below names the 15.4 Inch Hi-Lift Replacement Blade Kit, 20122P. This is the first of four consecutive runs naming the Atomic blade; the hi-lift comes back at 410243167.

The engine maintenance kit stops being named at all. The run below names 130-8146, and the one below that names 130-8149. Above this serial Toro names neither, for any of the six remaining runs that carry an accessory list.

That second point is the one that costs money to get wrong. Toro dropping the kit from a listing tells you what it sells for these serials and nothing about what the engine needs. This site records both kit numbers as unknown for this range rather than as absent, because absence from a catalogue is not a fitment statement.

If you are close to the edge

Serial numbers near a boundary

The lower edge is sharp and the run below it is consecutive. A serial just under 403600000 falls where Toro names the hi-lift blade and a maintenance kit; at or above it, neither.

Method

How we established this

We opened all eleven listings Toro publishes for model 21199 and compared the accessories they name against the parts this site holds. The count comes from the serial-range selector the pages carry. Ten carry an accessory list; 413000000–414709995 carries none, so nothing is scoped to it. Engine oils, a bag, a striping kit and fuel products other than 130-2393 appear on the pages and we hold no record for them.

The common mistake: Reading the kit’s disappearance as Toro saying the machine no longer takes one. The listings say only what Toro offers for each run.
