What changes at the edges of this run
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 the two runs we opened. The blade is common to both: 59534P, the 22 Inch Recycler Blade, appears in each. So on this machine the serial number decides one purchase and not the other, which is a narrower and more useful statement than the general advice to check your serial before ordering anything.
Toro publishes five listings for this model number and we have opened two — this one and the 316 series. The three we have not opened all sit later than this range, so nothing on this page describes a machine numbered 401500000 or above.

Listed for a neighbouring run, but not this one
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.

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 production runs of the 20340
Toro publishes 5 parts listings for this model number. We have opened 2.
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.
