What It Is

This is a complete 42-inch mower deck rebuild kit for select Toro TimeCutter and Exmark Quest/E-Series zero-turn mowers. It includes two spindles, two blades, two idler pulleys, and one drive belt—everything needed to refresh a worn-out cutting deck.

Fitment & Compatibility

• Deck size: 42-inch cutting deck only. Measure your deck width to confirm.
• Models: Fits Toro TimeCutter SS4235, SS4200, MX4260, SS4260, and Exmark Quest/E-Series models with a 42-inch deck. Verify your exact model number on the machine’s chassis tag.
• OEM vs aftermarket: This is an aftermarket kit. OEM part numbers referenced are Toro 121-0751 (spindle), 110-6568-03 (blade), 106-2175 (idler), and 119-8819 (belt). Cross-check your machine’s manual for these numbers.
• Measurements: Blade length is 18 inches, spindle shaft diameter is 5/8 inch, belt length is 119.5 inches. Confirm these match your current parts.

Key Things to Know

• Quality: Aftermarket spindles may have slightly looser tolerances than OEM. Inspect for burrs or rough bearings before installation.
• Installation difficulty: Moderate. Requires basic tools (wrenches, socket set, jack stands). Removing the deck makes it easier.
• Common gotcha: The idler pulleys may need a spacer or washer to align perfectly with the belt path. Keep the old hardware just in case.
• Belt tension: After installation, check belt tension per your manual. Over-tightening can damage spindles or the belt itself.

Should You Buy It

If your 42-inch Toro TimeCutter or Exmark Quest/E-Series deck has worn spindles, dull blades, or a slipping belt, this kit is a cost-effective one-stop refresh. It’s best for DIYers comfortable with moderate mechanical work who want to avoid buying each part separately. For commercial or heavy-use mowers, consider OEM spindles for longer life.
