Weird spindle design on a Commercial ZTR

[kwak]

I have a Scag and once you change the blades a few times it isn't that bad. One thing I like is that if your threads get messed up you just go buy a new nut/bolt and be on your way, you dont have to worry about having to fix/replace the spindle.

Yes that is the only benefit I see with a nut on the top of the spindles and some threads exposed, but if the threads are not exposed it reduces the risk of threads getting messed up pretty much to operator error only though.
Through bolt is design is really nice on a lot of applications and since you have these spindles, how much of the threads are exposed past the nut?

The original design of this spindle was so you could adjust the where the blades sit in the deck.

On my snapper you adjust the cutting height with one inch spacers on the front wheels. If you want to go up or down a half inch you use the spacers on the blades.
I run my blades a half inch above the lip of the deck.

By moving where the blade sits in the deck changes how it cuts.

If you want to stripe you can put the blade up higher in the deck.

The bolt is flush with the top of the nut so there are no threads exposed. I do think it is very important to make sure the nuts/bolts are torqued properly with this design.

We used to not really torque :/ we put them on tight and never had a problem. No you don't want them loose, but that's why you feed the bolt through the bottom if its loose your going to mess up your bolt but not throw a blade. It is really a heavy duty design

I put them very tight with a breaker bar.

I think every mower should have this set up. Everything just last so much longer.
