It has been mowed with a large deck before. I had a John Deere D130, standard lawn tractor, and it cut fine.

Since you bought it from a small shop they may send a tech out to you for adjustments. Plus they can see your lawn for troubleshooting purposes.
I just rechecked everything. Front to Rear was 1/4 more than spec’d in the manual. I had 1/2 inch and the manual calls for no more than 1/4 of an inch. I adjusted it back out and adjusted tire pressures. 15lbs rear and 20lbs front casters. We will see how this does the next cut. Thanks guys.
Did you get the anti-scalp wheels moved up to the higher holes?
I’ll do that before the next mow as well. Little Man (15 m/o son) keeps me busy. Only had time to check pressures and adjust the rake this evening.
Well, I leveled the deck front to rear (it’s level left to right), adjusted tire pressures to 15lbs rear and 20lbs front and raised the anti scalp wheels. No noticeable change in cut and it is still uneven.
I contacted Toro. Let’s see if they step up.

This is more prevalent cutting short … can you mow a setting higher so the deck pressure is less ?
Front of the deck should be 1/4 inch lower than the back of the deck.
Did you try swapping the blades around to see if it still does it on the same side?
so haven’t but I don’t think that would help. If you look at the pictures, the lines come from the downhill side of the deck. It’s almost like the mower just leans too much on the slight slopes.
so cutting the opposite direction makes it cut low on the opposite side? It’s hard to tell the scale of the lines from the pictures. Those don’t look 38-40” wide in the pic but that could just be the magic of pictures vs seeing in person.
Each line you see is from one pass down and one pass back. It leaves a line in both directions.
Very strange. I’d call the dealer you got it from and have them address if cutting it taller doesn’t correct it.
Lets look at your blades. Blade grind angles and surface finish can have a big impact on some lawnmowers some more than others. Do you know what angle the blades are sharpened at now? Typically a new blade can be 30, 35, or even 45 degrees. I can tell you those blades with 35 and 45 degree angle cut the blades of grass awful. Not only do they mostly rip the top of the grass blade off the also can push the blades of grass down somewhat when cutting in some areas of the lawn mower deck.
So I raised the deck 1/2”, from 2.5” to 3”, for this last cut and it appeared to do better. Maybe this machine just dislikes “short cutting”. Ill post pictures later when the sun comes up. 
Looks good and that could be the case for your particular grass and terrain.
I don't cut any shorter than 3" as well. Grass looks better, is healthier and it's easier on the equipment.
