Murray Idler Pulleys
Match the correct Murray idler pulley by checking your mower’s model number or the part number stamped on the old component before ordering. These pulleys keep the belt properly routed and tensioned, and worn bearings often cause a squeal or rumble even with the blades disengaged. If belts are wearing out too quickly, make sure the idler still turns freely. Garden Tractor Spares stocks genuine and OEM replacement parts for many Murray models.

Frequently Asked Questions
Do idler pulleys matter if the blades are off?
Yes, they still do the job of keeping the belt properly tensioned and guided. If a bearing has failed, it can squeal or rumble even when the blades are not engaged.
What does an idler pulley actually do?
An idler pulley helps tension the belt and keeps it running on the correct path. When it is working properly, the belt is guided smoothly through the drive system.
When should I change the idler pulley?
Replace the idler when it is worn, especially if you are fitting a new belt at the same time. A worn pulley can affect how the belt is tensioned and guided, so changing both together is the sensible repair.
