Production run

Toro 20340 partsSerial 401500000–404329999

All five of the 20340's listings are open. This is the last of three with no front wheel on it; 137-4833P appears in the next run and is in the last one too.

At your boundary

What changes at the edges of this run

Wheels and drive gears

—→137-4833Pat 404330000

Toro names no front wheel among the accessories for this range. The next listing, 404330000–405699999, names 8 Inch Front Wheel 137-4833P.

The two listings are consecutive, so this is where the wheel starts being offered rather than where we first noticed it. Nothing here says the earlier machines take a different wheel — only that Toro does not list one for them.

Covers and storage

—→490-2012at 404330000

Smart Stow Cover 490-2012 is not among this range’s accessories and is among the next range’s.

It arrives at the same serial as the wheel. Our reading is that the listing was extended rather than the machine changed, since a wheel and a cover have no common cause — but Toro states no reason on the page, so that is inference and not something the listing says.

In detail

This production run

This is the third of the five parts listings Toro publishes for model 20340, and we have now opened all five.

Of the parts this site holds records for, this range lists five: the 22 Inch Recycler Blade 59534P, the Briggs & Stratton EXi Engine Maintenance Kit Replacement 130-8148, the Traction Assist Handle 131-4590, the Cover for 20 to 22 Inch Walk-Behind Mowers 490-7462, and Premium Fuel Treatment (0.5 oz.) 130-2393. What it does not list is a front wheel, or a Smart Stow cover.

Both appear in the very next listing, 404330000–405699999, and both are still there in the last run. Nothing this range lists is missing from either of those two, so within the parts we hold the list grows at 404330000 rather than changing.

That matters for how you read an absence. If you have a 20340 in this range and you need a front wheel, this page cannot tell you 137-4833P fits it, and it cannot tell you it does not. Toro simply does not list a front wheel for these serials. Absence from an accessory list is a statement about what is offered, not about what bolts on, and this site records it as unknown for that reason.

The maintenance kit boundary on this machine is elsewhere — 20234 gives way to 130-8148 at 400000000, one range earlier, and that has its own page.

If you are close to the edge

Serial numbers near a boundary

The top of this range is a real edge and the listings either side of it are consecutive, so a serial in the last few thousand is worth reading twice. Below 404330000 Toro lists no front wheel for this model; at 404330000 and above it lists 137-4833P.

Method

How we established this

We opened all five of Toro’s parts listings for model 20340 — the count comes from the serial-range selector on the listings themselves — and compared the accessories they name, within the part categories this site records. Each page also carries items this site holds no record for — engine oils, grass bags, a striping kit, and fuel products other than 130-2393 — so this is not an exhaustive diff of the pages. A part absent from a listing is recorded as unknown rather than incompatible.

The common mistake: Reading the arrival of a front wheel as a design change. Two unrelated items appear at this boundary, which we take as a sign the catalogue was extended rather than the machine altered. Toro does not say, and neither can we.
