They said it couldn’t be done. They said the yard was too thick, too wild, too far gone. But then I slapped a replacement belt on my mower, and suddenly I was parting grass like Moses at the Red Sea.This belt doesn’t just spin blades—it summons storms. I saw it slice through Johnson grass so tall it had its own zip code. It screamed like a banshee at every turn, flinging grass clippings like confetti at a tractor parade. I’m pretty sure I mowed over a small tree, and the belt didn’t even blink.Tension? Perfect. Installation? A mild wrestling match, but I came out victorious, sweat-streaked and proud. And durability? Let’s just say this belt will outlive your mower, your dog, and probably your HOA.Bottom line: if your yard looks like a jungle and you’ve got the heart of a cowboy, this replacement belt is your lasso. Yeehaw.

It's a Deck Belt. Needed the neighbor to install. Not a do it alone job. Had to modify the crowbar so I could get the tension Idler back far enough for the neighbor to slip the belt over it. Not easy to do alone. As good as the $68 one at the local O'Reilly store. The man at O'Reilly's tried to make me think that the Amazon Belts don't have kevlar in them. I checked, and they do. Thickness is the same. Quality is as good as other store brands. It matches the original that was on the mower for a year. The mower is one year old. Grass got up on the mower deck and caused the belt to come off and get cut.

I was doing blade maintenance on my Toro MX5050 when I noticed that the Belt was barely hanging on. I ordered this as a replacement. The quality of the material seems fine, it is gray in color as shown in the photos for the item. It seemed identical in every way to the OEM belt that I removed in the sense of size, thickness and overall length. It was a bit "tight" to get over all of the pulleys, but that is to be expected with a brand new belt. I've only mowed a couple times since replacing the belt and if I was going to have any issues I would expect to have seen them by now. This was a perfect match for my mower.

Below is my initial review. The company reached out to me almost immediately and sent a free replacement belt. I received it with just a couple of days. So far it seems to be working much better than the first one. Fingers crossed it holds up for the rest of the summer! I definitely appreciate a company that goes above and beyond to take care of their customers!The belt fit my John Deere S110 riding lawnmower, but unfortunately the belt broke the 2nd time I used the lawnmower. More unfortunately it was right in the middle of trying to finish cutting my back yard. Now half the yard is cut and the other half has to wait until I can find another belt. Not saying this product is bad, but it did not work for me.

Belt part number 117-1018 fits the Toro recycler. Verify your mower model number for compatibilty. Its placarded on the top of the deck. Mine is 21445. There are several how-to videos on the internet showing how to replace the belt. For this mower the blade does not need to be removed, so you can pretty much ignore videos that do that. Other videos show the removal of a bracket that holds the front pulley in place. The Toro 21445 did not have this. It had a single screw connection for the pulley that needed a T20 star driver to remove it from the drive shaft. Simply remove the pulley, slide on the belt then reinstall the pulley. Much simpler. You still have to remove all the safety covers to get the belt onto the blade shaft pulley but that only takes a few minutes. It took me about 40 minutes for the first repllacement but now that I've got it down it would probably take less that 15. Just ordered another belt. I figure for less that $10 I would make changing the belt as part of annual maintenance.

I have a John Deere S180 (54 inch) mower, almost a year old , the belt broke. The local hardware store didn't have a replacement so I took a chance and ordered this one. What a difference! The mower rides better than ever and it mows like a dream! Excellent purchase! Not only is the quality of the belt superior it's way less than the JD belt! This will be the go to brand for belt replacements.

I replaced part GX26422 on my John Deere Z325E with a non-OEM belt. This is the third belt in three years for this mower, and the first two OEM belts didn't last. I'm hoping this one holds up better. So far so good.

Belt is too long and is not a match for the original. It slips and due to its length, I was unable to make up the slack by adjusting the riding mower's tensioners. Bought a PowerMax belt that was a bit more expensive but fit and worked fine.<edit 2025.05.13> Seller reached out and gave me a refund on the belt. Their customer service is trying very hard to make things right. However, I couldn't give them 5 stars because of the lack of fun it was to change the drive belt on my riding mower. I will give them another chance when I need to replace the belt again (although I hope that will be a year or two down the road; it's really not fun to have to change that particular belt).
