If your Toro Dingo TX 1000 with wide tracks is squeaking or throwing tracks, the tensioner wheel might be worn out. This is the genuine Toro part, number 133-8626, so you're getting the real deal, not some aftermarket knockoff. It's brand new, still in the original packaging, and ready to bolt on. Just make sure to check your model—it fits SOME Toro Dingo TX 1000 wide track machines, so double-check your parts diagram. It's a direct OEM replacement, so the quality and fit are exactly what Toro intended. Get your machine back in action and running smooth.
