Mower blades

20120P→20122Pat 410243167

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

The hi-lift is not a newer part arriving. Toro names it for the two earliest runs of this model number, then not for four, then here and for every run above.

In detail

This production run

This is where the 21199's blade goes back to what it was.

Toro names the 15.4 Inch Hi-Lift Replacement Blade Kit, 20122P, for this run. The four runs directly below name the 15.4 Inch Atomic Blade, 20120P, and the two runs below those name the hi-lift again. Across the eleven listings Toro publishes, the pattern is hi-lift, Atomic, hi-lift.

A part number that comes back is the reason this route family exists. Compare only the earliest and latest listings for this model — the obvious thing to do — and the blade looks unchanged across the machine's whole life. Compare only the middle, and the Atomic blade looks like the current part. Both readings are wrong, and only reading all eleven runs shows it.

No engine maintenance kit is named for this range, or for any run above 403599999. That is recorded as unknown rather than as an absence of need.

Method

How we established this

We opened all eleven listings Toro publishes for model 21199, 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; 413000000–414709995 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 this machine it moves back, and a retailer listing built from one run will not tell you that.
