Production run

Toro 21200 partsSerial 404320000–405699999

The last 21200 run naming Atomic blade 20120P. Hi-lift 20122P returns in the run directly above and holds for every run after. All eleven are open.

Mower blades

20120P→20122Pat 405700000

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

The hi-lift is not arriving for the first time — it is what the two earliest runs name. It leaves for two runs and comes back, and a part number that returns is not something a retailer listing will show.

In detail

This production run

This is the second and last 21200 run for which Toro names the Atomic blade.

At 405700000, the listing goes back to the 15.4 Inch Hi-Lift Replacement Blade Kit, 20122P — the same number the two earliest runs name — and stays there for every run above. The two listings either side of that serial are consecutive, so it is a real edge.

Across the eleven listings, the 21200's blade reads hi-lift, hi-lift, Atomic, Atomic, then hi-lift for the rest. Two runs out of eleven take the other blade, and they sit in the middle where nobody looking at the first or last listing would find them.

No engine maintenance kit is named here, as none is named for any run above 403599999.

The 21199 does the same thing with the same numbers over four runs instead of two. If you have been given a blade number for "the TimeMaster", it is worth knowing which of the two machines and which serial it came from.

If you are close to the edge

Serial numbers near a boundary

The upper edge is sharp and the listing above it is consecutive. A serial in the last few thousand of this range still names the Atomic blade; one digit higher and it is the hi-lift.

Method

How we established this

We opened all eleven listings Toro publishes for model 21200 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. The count comes from the serial-range selector the pages carry. 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: Reading the middle of a model’s run as its final specification. Two of this machine’s eleven listings name the Atomic blade and nine name the hi-lift.
