Front Wheel Drive (FWD) Traction Cable Compatible with Toro 21442 21445 21447 21770 22" Recycler Lawn Mower Replace#: 140-3947

What It Is

The Front Wheel Drive (FWD) Traction Cable (OEM part# 140-3947) engages and disengages the self-propel drive system on specific Toro 22" Recycler lawn mowers. It connects the handle-mounted drive control to the transmission, allowing you to move forward without pushing.

Fitment & Compatibility

Before buying, confirm your mower’s model number (found on a sticker under the seat or near the rear wheels). This cable fits:

• Toro models: 21442, 21445, 21447, 21770 (all 22" Recycler with FWD)
• Deck size: 22 inches only – will not fit 21" or 24" decks
• Drive system: Front wheel drive (not rear wheel or all-wheel drive)
• OEM vs aftermarket: This is an OEM Toro replacement, not a generic aftermarket cable. It matches factory specs for length and attachment points (approx. 42" overall length, includes both cable and housing).
• What to check: Measure your old cable from end to end (including housing) – if it’s 42", this is the correct one. Also verify your mower uses a single cable (not dual cables) for FWD engagement.

Key Things to Know

• Installation difficulty: Moderate – requires removing the handle cover and routing the cable through existing clips. Plan 20-30 minutes with basic hand tools (screwdriver, pliers).
• Common gotcha: The cable housing ends can be tight to snap into the handle control bracket. Use needle-nose pliers to seat them fully, or the drive won’t engage properly.
• Quality: OEM part means exact fit and same durability as original – no need to adjust cable tension after install if routed correctly.
• Check for wear: The cable itself rarely fails; the plastic housing ends crack or the inner wire stretches. If your old cable is frayed or the housing is split, replace it.

Should You Buy It

If your Toro 22" Recycler’s self-propel has gotten stiff, won’t engage, or the handle lever feels loose, this is the correct fix. It’s a direct OEM replacement, so no guesswork with fitment. Only buy if your model is listed above and you’re comfortable with a simple cable swap – otherwise, consider a shop install.
