Choosing this part
The driven rear wheel Toro lists for the 20334 in all three serial ranges we verified — one of the few parts on this machine that does not move. Note it is the rear-wheel-drive wheel: the 20339 drives its front wheels and does not list it.

The next published range. Lists 130-8148 (Briggs & Stratton EXi Engine Maintenance Kit Replacement) and 131-4590 (Traction Assist Handle) where the previous range listed 20234 and 108-8120. Still lists 59502; 137-4833P does not appear.

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.
