One final thought on this.
I think this has been a good constructive conversation and would like to bow out before it turns for the worse. So my final thought is this. I'm guessing the engineer that designed this has more knowledge of how this should work than any of us here. I doubt that the holes were meant to just get get clogged up with grass and do nothing. I also looked at some spindles from some othe high vac decks and saw that there were openings where they mounted to the decks also. There's definitely some reason for this design and I think it has everything to do with vacuum

all of the ones I have mowed with do push grass up through those holes [especially dry grass] that's why the top of the deck is always covered with grass . if the pulley gaurds are in place they're usually plugged solid from not being cleaned out

Ok. so air is pushing up from there. Do you use with mulching cover on or side discharge open? I am actually reading one of the patents right now for this design.. Its a long read tho lol.

Hmmmmmm...... so air isn't sucked in from the top through those holes. Who would have thought that?

How about someone who has this type of deck hold a piece of paper near the opening while running the mower. The deflection of the paper will indicate air flow direction.

Jon, Perhaps I was thinking of this backwards. Do you think with a mulching cover in place that those vents may be necessary to create the vacuum? In other words, If the deck was sealed shut would it create as much flow as it would with out some sort of vent like the ones in question? Does the deck work as efficiently once those holes become plugged up?

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
