Id be tempted to buy them, i have a brand new camso for my Delta track sitting in the shed was worked into the deal when i bought the tractor, dealership said when it was all said and done it was 18ish grand for that track.
But because they couldnt get one during covid i had to buy a gtw brand and that came to about 14 all said and done a couple years ago. Then install.
Thats for the 3500 camso and gtw equivalent in a 30 inch track I think those snoebears are 6500 equivalent.
