Make sure that you understand the "glitter" issue, as to where it comes from, and when it is created,,
#1 - The glitter level should not increase during mowing, as the button should not be in contact with the clutch,
there should be a literal air gap between the button, and clutch,, air gap, = no glitter.
#2 - The glitter level should not increase when the mower deck is not spinning, the clutch assembly is not turning,,
no turning = no glitter
When does glitter get created? only during the few seconds that the mower deck is changing from rotating to stopped.
THEN,, there is the BIG NO - NO that causes LOTS of glitter,,
#3 - You create LOTS of glitter when the mower belt is removed from the clutch,, and you pull the cart.
The clutch will be spinning, and the button is touching the clutch,,
SOLUTION!?

Operate the tractor with the PTO engaged when pulling the cart,,
The button will not be touching the clutch, glitter will not be created.
I always thought that this Glitter info should have been a dash decal on the Cub Cadet,,,
LOTS of PTO clutch buttons have been destroyed over the years by running the tractor with the PTO disengaged, and no attachment on the tractor,,
