Engine maintenance kits
20234→130-8148at 400000000
Kit 130-8148 is listed for this range; the 316000001–316999999 listing shows 20234 instead.
Those two listings are consecutive in Toro’s own list, so this serial is where the change happens rather than where it first becomes visible to us.
In detail
This production run
Toro lists the Briggs & Stratton EXi Engine Maintenance Kit Replacement, 130-8148, for a 20340 in this range. The preceding listing shows 20234 in its place.
That is the only difference between this run and the one directly below it. The blade is common to both: 59534P, the 22 Inch Recycler Blade, appears in each. Across the five listings Toro publishes, the serial number decides two purchases on this machine — the maintenance kit at this boundary, and the front wheel at 404330000 — which is still narrower and more useful than the general advice to check your serial before ordering anything.
Toro publishes five listings for this model number and every one of them has been opened. This page describes the 400000000–401499999 run only; the ranges above it are covered by their own pages, so nothing here describes a machine numbered 401500000 or above.

Absence from a parts listing is not a statement that a part does not fit. It is the manufacturer not saying.
20234 Not verified
Toro does not list kit 20234 on its parts page for serial range 400000000–401499999; that range shows kit 130-8148 instead. We have not found a primary source stating whether 20234 also fits the later range, so we are not making a claim either way.
137-4833P Not verified
Toro does not name 8 Inch Front Wheel (137-4833P) among the accessories on its parts page for model 20340, serial range 400000000–401499999.

If you are close to the edge
Serial numbers near a boundary
A serial just below 400000000 falls in the previous range, where Toro lists 20234. That boundary is exact, because the two listings are consecutive, so a single digit decides which kit the listing shows.
Other runs
Other production runs of the 20340
Toro publishes 5 parts listings for this model number. We have opened 5.
Method
How we established this
We compared Toro’s parts listings for model 20340 under serial ranges 316000001–316999999 and 400000000–401499999, recording, within the part categories this site records, every part that appears in one and not the other.
The common mistake: Assuming the blade changes whenever the kit does. On this machine the blade is the same on both sides of the boundary.

Toro’s official parts listing for the later serial range of the same model number. Lists 59534P and 130-8148 (Briggs & Stratton EXi Engine Maintenance Kit Replacement) — note the maintenance kit differs from the earlier range.

Engine Maintenance Kit for Briggs & Stratton Engine (Part # 20234)
The Toro Company · Primary source · Accessed August 31, 2026
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). It carries no line saying this kit replaces another number or has been replaced by one. **Re-read 31 August 2026 and unchanged in every particular, including the 0.5 oz.** — which matters, because the page Toro serves for 130-8148 gives the same packet as .05 oz. Two further details this record had not held: the internal designation TORO WPM MAINT KIT - BRIGGS, and a Specifications row reading Service Pack Yes.
