Welcome to TBN
Sounds like you have covered the correct way to get the deck "level" for carrying it at the height you want.
Maybe something in the deck or the support is bent?

Have you tried measuring scalp wheel location on the deck in relation to blade height? Just wondering if something on the scalp wheel mounts could be bent a little.

Are your tires aired up properly (ie: one isn’t low on air, causing the deck to be uneven)?

What I do for reference is to measure below the blades side to side, check pitch and adjust if needed. Rinse and repeat. Then set the wheels ~ 3/4" off the concrete. 1) The blades cut the grass, not the bottom of the deck. 2) A 42" deck hardly needs them at all and isn't meant to be used with the wheels on the ground anyways.

This is the way I adjust my blades on the x584. There is a specific tool that makes measuring the blade height very easy. Something like this:

The anti-scalp wheels are adjustable, if the deck, tires and blades are correct adjust the wheels.
