Selection

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.

    Toro’s official parts listing for the earliest of the three ranges we verified. Lists 20234 (Engine Maintenance Kit for Briggs & Stratton Engine) and 108-8120 (TRACTION ASSIST KIT [PPG2]). Also lists 38991, 59534P, 59502, 59503 and 490-7462. The range selector on this page names thirteen further serial ranges for the same model number.

    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.
