I know this has been covered several times, I thought I bookmarked it too.
When a data tag is missing there are ways to tell what gear set is inside by the addition of a bolt or a washer etc from the factory. Can someone in the know add that info here please?

From Chip Old at the Yahoo Gravely Club-




Jack up the tractor so one tire is off the ground. Make sure the other wheel
remains on the ground, or find another way to prevent it from turning.
Remove the spark plug and (if electric start) the starter chain so the
engine can be turned over by hand. Rotate the crankshaft and count how many crankshaft revolutions it takes to rotate the wheel 1/4 turn.

L or C
8-lead worm
1/4 wheel rotation requires 6 crankshaft rotations.

LI or CI
6-lead worm
1/4 wheel rotation requires 9 crankshaft rotations.

LS or CS
4-lead worm
1/4 wheel rotation requires 12 crankshaft rotations.

Another quick way to identify the number of leads is to push the tractor in neutral. An L is fairly easy to push. An LI is noticably harder to push and an LS is next to impossible to push around.
