See photo, Is this suppose to have a cover? I just had the tractor returned for a faulty seal around a drive shaft, after 16 hours. I crawled under there to see what they did and noticed the large opening in the picture. Sorry, I don't know the exact part names. Seems odd this would be open to allow all kinds of dirt to get right into the clutch assembly. I didn't think that was open like that prior to the dealer picking up the tractor. There's no apparent holes for any bolts that would have any type of cover plate. Is it some kind of snap in cover?
