## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect replacement cap for my older MTD push mower.
*by G***L on May 27, 2025*

Great high quality cap. Fit exactly on my MTD budget mower. My original cap had disintegrated after 8 years sitting outside. No local stores had a cap replacement, and this one was a perfect fit. Cap appears to be high quality plastic.
