Those look like Hiqual tracks which are an OEM option from Takeuchi. I just bought a set of them for my tl130 this summer. Bout 200 hours on them so far and I love them. They ride good and bite really well. They clean out much better in mud than a C pad. They aren't really turf friendly is their only drawback.
I think I paid about $700 each for my tl130. They were free shipping to my local frieght terminal or a commercial address.
Call the guys at Hiqual and you can buy direct and save a good chunk. They were awesome to work with. Shipping was two days to KCMO.
