-24T
Bottom sprocket
-35T: M65809 original lower sprocket for Liquifire and Trailfire 340
-38T: Aftermarket, combine with an original 22T Liquifire upper sprocket and a 68 link chain for a little more umph off the line
-39T: M65693, 22/39 is the recommendation from Deere for low end performance in service info M81-50-11, also requires a 68L chain
-40T: Aftermarket, combine with the 24T above for an in-between ratio
I've also got a number of 68L, 66L, and 62L chains. Check the JD Fine Tune Manual for chain/sprocket combos (below).
