What It Is

This 42-inch deck rebuild kit bundles two spindle assemblies (OEM #117-7439, 121-0751), two blades (#110-6568-03), two idler pulleys (#106-2175), and one drive belt (#119-8819) for a single-source refresh of the cutting deck on select Exmark Quest E/S Series and Toro TimeCutter SS4200, SS4235, and MX4260 mowers.

Fitment & Compatibility

• Deck size: Only for 42-inch stamped steel decks. Do not use on 44-inch, 46-inch, or fabricated decks.
• Exact models: Exmark Quest E-Series (2016–2023), Exmark Quest S-Series (2016–2023), Toro TimeCutter SS4200, SS4235, and MX4260. Verify your model number on the frame tag.
• OEM cross-reference: Spindle 117-7439 (replaces 121-0751), blade 110-6568-03, idler 106-2175, belt 119-8819. Aftermarket parts may vary in bearing quality and belt length tolerance.
• Before buying: Measure your existing belt length (should be ~119.7") and spindle shaft diameter (must be 5/8"). Confirm your deck has two idler pulleys (some early models used one).

Key Things to Know

• Quality vs OEM: Kit uses aftermarket spindles and blades. Spindle bearings are sealed but may not last as long as genuine Toro/Exmark parts under heavy use. Blades are standard-grade steel—not hardened.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (spindle nuts to 45–55 ft-lbs), and a spring puller for the belt tensioner. Expect 1–2 hours.
• Common gotchas: The belt may be slightly shorter than OEM—check tension after installation. Idler pulleys have a specific orientation (flat side out). Reuse your deck pulley bolts if they aren’t included; aftermarket bolts can be soft.
• Warranty: No stated warranty from seller; inspect all parts immediately for defects.

Should You Buy It

Buy this kit if you need a budget-friendly, single-order solution to refresh a worn 42-inch deck on an older Exmark Quest or Toro TimeCutter, and you’re comfortable with moderate DIY work. Skip it if you want OEM-grade longevity or are restoring a commercial-use mower—buy genuine Toro spindles and blades separately.
