I just got these blades for my craftsman LT2000 but I don’t know which side face down or how to install them in which side up or down?it matters

Put the 3 pointed sides facing upwards towards the lawnmower that's what makes the grass fly up and get cut again when the blades are spinning

Do these work I have bags on my mower?

The answer is a 100% no, anyone else saying yes doesn't know what their talking about, these mulching blades have Low/ Almost Zero Lift on the blades so theirs no throwing power, to bag you need medium or high lift blades, these are. I have both a standard 3 system bagger and a yard vacuum we use in the fall for acorn/leaf pickup that sucks and mulches inside or simply sucks up stuff (acorns). Bought the 42" set and tried them out on leaves, they pulverized as advertised much better then the yard vacuum grinds them up but their is no way to pick them up without actually powered suction. A bagger will get clogged halfway up the tube before it reaches the bagger. Again no lift blades = no bagger abilities.

Can you use these with a side discharge or do you 'have' to have the cover?

My mower has side discharge and no cover and work just fine these are good blades I have a Poulan 42" cut

The blades arrived but the center mounting holes are diffent on each blade. One has the star center hole and the other blade has a round hole.

Sounds like they sent the wrong one they should both have the star center hole. Get replacements I love these blades have had them on for a year and still cut and mulch great.
