FAQs
Can I use a universal belt for my Murray mower?
It’s not recommended. Belts are engineered to specific lengths and tensions. A universal fit may reduce mower performance or cause early wear.
How often should I replace my mower belts?
On average, every 2-3 mowing seasons depending on usage. Always inspect belts annually.
What if I can’t find my exact model in the chart?
Use the part number from the owner’s manual or consult Murray’s customer support with your model and serial number.
