Did you ever get new tracks? The OEM tracks are usually designed to not tear up the turf and float well especially on nice lawns. If that's important to you, spend the extra bucks and get the OEM tracks. If you don't care about that, and just want good grip there may be some good options out there. I've bought Summit tracks, and I think they work great on my track loader and mini excavators. When I went to replace my Toro Dingo though, I bought the OEM brand because I like the way they flatten and compact the dirt, and float and not disturb lawns.
