Toro 20334 — 22 in. Personal Pace Electric Start Mower

A 22 in. rear-wheel-drive walk-behind mower with Toro’s Personal Pace drive and electric start, powered by a Briggs & Stratton EXi of 163 cc. Toro publishes fourteen separate parts listings for this one model number, and the parts are not the same across them — the engine maintenance kit changes between the 315- and 316-series ranges, and the front wheel changes again between the 316- and 400-series ranges. Your serial number decides both.

Identification

Where the numbers are on this machine

On the housing — top rear, back rear, left side, or right side — or on the underside of the control panel. Write the serial number down while you are there: on this mower two different parts change at two different points in the serial sequence, so the model number on its own is not enough to order from.

Covers and storage

  • 490-7462
    Cover for 20 to 22 Inch Walk-Behind Mowers

    Listed by Toro on its official parts pages for model 20334 under all three serial ranges we verified, described as a cover for 20 to 22 inch walk-behind mowers.

    Condition: Toro lists this cover for the machine, but sells it by a deck-width range — 20 to 22 in. — rather than for this model specifically, and publishes no measurements for it. We therefore cannot tell you it fits, only that Toro lists it.

    Conditional fit

Fuel treatment

    Premium Fuel Treatment (0.5 oz.)

    Listed by Toro on its official parts pages for model 20334 under all three serial ranges we verified. This is a fuel treatment rather than a fitted part.

    Confirmed fit
We only list parts we have found on a manufacturer source for this machine. A part missing from this page is not a statement that it does not fit — it means we have not verified 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.
