Good To Know

Q: How do I know this pulley fits my Exmark or Toro mower? A: Cross-check your existing part number with 136-5404 or 114-5895, and measure the pulley diameter and bore size to confirm compatibility.

Q: Will I need to replace the bolt or spacer when installing this pulley? A: You can reuse the original mounting bolt and spacer if they are in good condition, but we recommend inspecting them for wear and replacing any corroded hardware.
