59534→59534Pat 313000001

This range names blade 59534P. The listing directly below, consecutive with this one, names 59534 and not 59534P.

Toro states this one outright rather than leaving it to be inferred: its product page for 59534 serves the 59534P page under the line “Replaces Product 59534”.

Engine maintenance kits

—→20234at 313000001

Kit 20234 is named here and is not named in the listing directly below, which is consecutive with this one.

This is the earliest 20334 serial whose accessory list carries an engine maintenance kit. The four listings below carry none — which is what those pages show, not proof that no kit can be ordered for those machines by another route.

In detail

This production run

Engine maintenance kit 20234 enters the 20334's parts listing at this serial and stays for four runs, through to 315999999. Toro itemizes it as 20 oz. of SAE 30 oil, a spark plug, an air filter and a fuel treatment packet.

The listing directly below this one names no kit at all, and neither do the three below that. Those two runs are consecutive in Toro's selector, so this is the edge itself.

What else is on this page is short. Of the parts this site holds, Toro names three: the kit, the traction assist kit 108-8120, and the 22 Inch Recycler Blade 59534P. No drive belt, no wheel, no gear, no cover — five of those appear two runs later, at 315000001, which has its own page.

The blade is worth a second look here. This is the first 20334 run Toro lists 59534P for; the four runs below it name 59534, the 22 Inch Atomic Blade, which Toro's own product page says 59534P replaces.

The kit number does not stay 20234 either. From 316000001 the listings name 130-8148 instead — which is a change in what is listed, not a statement by Toro that one replaces the other; the 20234 product page says nothing of the sort. On contents the two are not alike: 20234's own page itemizes it, while 130-8148 is itemized only on the page its URL now serves, for the replacement part 20298.

If you are close to the edge

Serial numbers near a boundary

The lower edge is the sharp one and the listing below it is consecutive. A serial a few thousand under 313000001 falls in a run for which Toro names no kit, so check the plate before ordering 20234 on the strength of this page.

Method

How we established this

We opened all fourteen listings Toro publishes for model 20334 and compared the accessories they name against the parts this site holds. The count comes from the serial-range selector the pages carry. Loose-parts kits, replacement bags, engine oils and a striping kit appear on the pages and we hold no record for them.

The common mistake: Assuming a kit listed for a model covers every serial of it. On this machine four runs precede the first one that names a kit, and four more replace it with a different number.

Requesting the 59534 product URL serves the 59534P product page, and that page carries the line “Replaces Product 59534”. This is Toro stating a supersession between the two numbers directly, rather than us inferring one from a parts catalogue naming a different number for earlier serials.

Toro’s product page for the kit, and one of the few in this family that is a page for the number requested rather than for a part replacing it. It itemizes the kit: 20 oz. SAE 30 engine oil (120-3306), a spark plug (120-3305), an air filter (120-3303) and a 0.5 oz. packet of fuel treatment (130-2393).
