Lawn Mower Pulleys and Idlers

Lawn mower pulleys play a decisive role in the overall functionality of the mower. From transferring power from the engine to the blades to the blade speed control, which in turn affects the efficiency depending on the type of grass or terrain. A lawn mower pulley is the centerpiece of the lawnmower from whichever side or angle you look at it. At UDC parts, we understand this and offer our customers and partners a choice of dozens of high quality options, including small engine pulleys.

Mower Idler Pulleys

The pulley system looks like a pretty simple mechanism. Visually, the various models differ from each other minimally and can fit dozens of lawnmowers from different brands. Despite this simplicity, it is the idler pulley that is responsible for belt tensioning. If these two mechanisms work together correctly, we get smooth operation and reduced wear and tear on the components.

OUR CUSTOMERS TALK ABOUT US

You know, I really enjoy taking care of my lawn. But you know what I don't enjoy? Dealing with machinery, finding the right parts, and definitely not replacing them. With UDC Parts, everything was easy. They have precise tips on compatible models and even short installation instructions for some of the products. I managed to do it all myself, and it turned out perfectly.

Just as good as original
The first time that I purchased this belt, it went on with ease and seemed to perform really well. I bought another to keep on the shelf in my work shop in case another belt broke. The belt on the mower broke and the replacement on the shelf was not the same size.

Way better than other belts
I went through 3 of the slightly cheaper belts you can get through Amazon, all of them kept slipping and jumping and snapping. This belt is only 5$ more and is way better quality. It's also slightly wider than the others I got, so fits in the pulleys snuggly. Don't waste money trying to save a couple bucks and just get this one the first time.

Best deal I found
I had preciously purchased chain for my saw at local vendor. I decided to try these since there price was about half as much as I had paid before. They turned out to be as good if not better than the expensive ones. I know where I will buy my next replacements.
