Selection
Choosing this part
Toro lists this front wheel for the 400-series range of the 20334, where the two earlier ranges we verified listed drive gear 59502 instead. This is the second of the two boundaries on this machine, and it is not the same boundary as the maintenance kit’s — which is exactly why "check the serial number" cannot be reduced to a single cut-off date.

The later range. Still lists 130-8148 and 131-4590, so the maintenance kit does not change again here. It lists 137-4833P (8 Inch Front Wheel) and does not list 59502 — a second, separate boundary within the same model number.
