Just got off the phone from the company that starts with the letters MC... They make the over the tire tracks. These people do NOT have their act together! After a month of waiting for the replacement tool (one that I have was redesigned because of a flaw..they freakin break!)to put these things on I just learned that I had to purchase it. This is after I was told it was a free replacement. I only had these tracks for 2nd season and the POS tool broke. I was left high and dry. I would have just went to a machine shop to make a new piece but I was told it was in the mail week after week. Talk about wear on these things! I purchased the rubber tracks and the rubber breaks and rips off the tracks! You would not think these would have dry rotted by the second season. They were made not to last so you will have to buy replacement pads at .5 the cost of new tracks!!!! After all of this I stopped in my local NH dealer and have a friend that works their. He just told me that over the tire tracks VOIDS any transmission warranty!!!! It puts undo strain on the entire machine. I was told differently by the same company mentioned above! Make your own decision on what to do. My hopes are that us skid steer owners stick together and stop taking crap from these businesses who could care less about you! BTW.. 86 hours on tracks!
