Listed for
Toro 20334 from 400000000, and Toro 20340 from 404330000 — to the end of production on bothThis value named one range of one machine, which is what was open when it was written. Every range of both machines has since been read. On the 20334 Toro lists this wheel in all five of its 400-series ranges and in none of the nine earlier ones, so it enters at 400000000. On the 20340 it appears only in the last two of five ranges, entering at 404330000. Both machines take it from that point to the end of production — but the two entry serials are more than four million apart, so a serial that means "yes" on one of these mowers means nothing on the other.

Selection

Choosing this part

The front wheel Toro lists from 400000000 on the 20334 and from 404330000 on the 20340. On the 20334 the two ranges immediately before it — 315000001–315999999 and 316000001–316999999 — list drive gear 59502 instead, and they are the only two of that machine’s fourteen ranges that do. This is the second of the two boundaries on the 20334 and it does not fall where the maintenance kit’s does, which is exactly why "check the serial number" cannot be reduced to a single cut-off date — not even for one machine, let alone across two.
