Just bought this sled and I was wondering if the chain was a 13 or an 11. Going water crossing tomorrow and I have some 13 width gears kicking around and dont know if they would fit. The sled will only be used for this and maybe some grass.

Just took it apart and it is the wide 13 gear. Now have 23/44 on it instead of the 25/44 gears. It fit on with the same chain. It is tossing out some nice chunks of lawn now.
