MTD deck height

[Gord Baker]

I picked up a MTD 13AQ608H729 riding mower. Runs and mows good. The problem I have is the deck height. On the highest setting the blade height is only 3 inches. I don't see any way of adjusting the deck height any higher. I have leveled it side to side and front to back. Is there a way to raise the deck higher?

No photo but I found on a recent restoration of a LA125 that the trunnions on each side were badly worn on the 'P' Bolts.
