Don't know about that particular machine, but all you need to do is identify the TYPE of chain fitted. Most common is 3/8" pitch, 0.050" drive link width, low profile, but there are others (usually it's just the 0.050" dimension that's different). Once identified (local garden machinery supplier), you just need to count the number of drive links, and order by length (ebay works for me!). Get a branded chain - Chinese chains are made from toffee.
