Ok I have put new spindles, new blades, and still the blades are uneven when you spin together, my brother does all the work and is very smart! Need advice of what to do next! Deck is level was cutting fine when a spindle went bad now it it is awful! I read somewhere that you could shim the spindle but do not understand how and why that would work, blade is only out on one side! Craftsman 42 in. Model 917.270532! Thanks for any info!

Take the blades off and lay one on top of the other to check for a bent blade. They should match perfect. I realize they are new but just do it before doing something completely un-necessary.
If the blades are true make a gauge similar to this one so measurements can be recorded since there will be several measurements and numbers aren't something we need at this time. Install the styrofoam strip so the bottom end reaches the bottom of the gauge.
Park the tractor on a known ( flat ) surface ( no need to be level, just flat ) , with tire pressure correct and deck height set about where you usually choose to mow. Position the left blade 90° to tractor length and check both cutting edges of that blade for height while in that 90ï½° position and compare. Only one mark should appear on the styrofoam strip or very close depending on how flat the surface is the tractor is on. Label that strip left blade cutting edges etc.
Install a new strip and repeat that procedure on the right hand blade.
After checking both blades then the two can be compared for height from the base of the gauge.
That's good enough for now until we determine those readings to see if, or where things are off.
