Fitment note: If your mower’s full model number exactly matches one listed above, it is a documented 127-3408 clutch path. Do not order by a broader name such as TimeCutter, SS5000, MX5000, ProLine, or Quest alone, because other models and production ranges may use a different PTO clutch. When available, also match the original clutch number or confirm 127-3408 in the model- and serial-specific parts diagram.
