I have a tow kit in the back of my sled that has had a fair bit of use, but it has never been used for my sled, only others.
Number one most popular brand of sled that needs to be towed by me= Arctic Cat.
Fun when I had a '98 Vmax 600, with 18,000KM on the motor that had never had any work done, tow out a brand new 2009 arctic cat 1000 whos turbo had overheated and lit the sled on fire. Made my old iron look(and feel) like a hero. To say the guy was a little red in the face when he saw what was towing him home would be an understatment.
