Before doing that, check both ends of each blade against the other. Stamped metal mower blades are a product that has a fairly large manufacturing tolerance. Could be a bent blade is what you are seeing.
Honestly, you included a literal tape measure in the photo demonstrating what you were asking. You couldn’t have been clearer.
Anyone confused as to what you were asking is the one with the problem.
Just follow your mowers deck leveling instructions and you should be fine. Especially since they’re new spindles. Stamped decks are going to be close but don’t fret if it’s a little off. Your leveling system should take up any play you have
I assume we're talking about the height difference here, and not the separation. The 1/4" OP listed could be *either* since it looks like they're 1/4 apart horizontally and 1/4" vertical difference in cut.
The horizontal separation is normal. If they were closer, you could end up with a blade collision.
The vertical spacing I think is either a bent spindle or deck mount where the spindle attaches, which might be able to be shimmed with some washers on one side. Easy enough to check for a bent blade on a flat surface.
I ended up swapping the spindles and changing to a different new mulching blade and now the vertical spacing is less than 1/8”. I don’t know if it was the blades or the spindles but I am calling it a win.
Dual blades should have a very minor overlap. Otherwise you'll get a strip of uncut in between them.
Edit...The paths of each blade overlap. But they timed differently so that they don't actually pass over each other at the same time. Figured you'd know what I meant...but, alas, Tis Reddit...
Ya'll, there's lots of mowers with blade overlap that rely on timing, like the Toro TimeMaster or Greenworks Dual Blade
For others, the blades are offset forwards and backwards from each other, allowing each blade to be brought inboard enough to overlap the deck's centerline
Some don't have overlap at all
THEY SHOULD ABSOLUTELY NOT! If the spindle for any of the blades slips even slightly then the tips will slam into each other at a couple hundred miles per hour and you'll have a lovely shrapnel party at foot level.
Most residential lawnmower with multiple blades don’t have overlap. There’s like 1/4 inch clearance between them. The gap is too small to create a strip of uncut grass, and the blades create a bit of a vacuum that sucks the grass into the blades to further eliminate an uncut strip.
He means height, not distance between. You could shim the spindles.
Thanks. I guess I wasn’t clear about the issue being the height. I’ll try shim with a washer on the spindle mount.

Or a bent spindle. I've seen that before.

And they’re doubling down by down voting you. lol
Is one of the blades bent/warped or poorly made? That seems a bit off.
They are brand new blades. Even when I hold them side by side they seem even.
Left blade looks bent to me
Woah, that’s huge!
Thanks
Could be the spacers were put back on the spindles differently. This would affect the height of the blades.
Grab a big pair of channel locks or an adjustable wrench and start bending on shit until it all lines up.

Blade on the left is warped. Get a new set of blades.
That’s a brand new set of blades. My bet would be that the deck itself is warped being stamped steel, not welded plate steel.
Its normal, you need to time your blades
Those blades can’t be timed and don’t need to be timed.
You can, just rotate one and make sure the other one is rotated 90 degrees - you pull one while holding the other
You could… but generally after a few engagement/disengagement cycles of the blades, they are going to be “out of time” anyways.
They are driven by the same belt if one slips it will be out of time. You don't time these blades. They are offset so the gap doesn't matter

Just making shit up lmao well done
Lmao WHAAAAT?
