What It Is

This is a replacement drive system for Toro 22" Recycler RWD (rear-wheel drive) push mowers. It includes two 8-inch plastic wheel gears (part #115-4695 / 138-3216) and a pinion gear kit (#115-4668), which together transfer power from the transmission to the rear wheels for self-propelled operation.

Fitment & Compatibility

• Deck size: Only fits 22-inch deck Toro Recycler models—do not use on 21" or 30" decks.
• Model numbers: Compatible with Toro 20332, 20333, 20334, 20338, 20352. Check your mower’s model number tag (under seat or near rear wheel) before ordering.
• OEM vs aftermarket: This is an aftermarket set, not genuine Toro. It matches OEM part dimensions but may differ slightly in plastic composition or gear mesh tolerance.
• Measurement check: Measure your existing wheel gear outer diameter (should be ~8") and tooth count (typically 20 teeth). The pinion gear kit must match your transmission output shaft diameter (usually 5/16" or 3/8").

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the rear wheels, pull the old gear from the wheel hub, and press in the new one. A gear puller or hammer and punch may be required if the gear is seized.
• Common gotcha: The pinion gear kit includes small retaining clips and washers—don’t lose them. If your transmission shaft is worn or bent, the new pinion may not engage properly.
• Quality note: Some users report the aftermarket plastic is slightly softer than OEM, which can lead to faster wear if you mow thick, wet grass regularly. Lubricating the gear teeth with silicone grease helps.
• Sold as a set: You get two wheel gears and one pinion kit—ideal for replacing both rear wheels at once, but you’ll need to buy a second pinion kit if both sides are damaged.

Should You Buy It

If your Toro 22" Recycler RWD has stripped or chipped rear drive gears (common after 2–3 seasons of heavy use), this is a cost-effective fix at $31.90. It’s best for DIY owners comfortable with basic mechanical work and who want to avoid a $60+ OEM replacement. Skip it if you need exact factory fitment or have a mower with a damaged transmission—then buy genuine Toro parts.
