I have a King Kutter 6ft. rotary mower. I'm trying to get the blades off to tighten the gear box which loosened up. I removed the 1 1/2" nut. It looks like there is some kind of nut inside the blade plate, something that gets loosened by banging it with a screwdriver? The manual isn't showing whatever it is inside. I assume there must be some kind of splined nut on the shaft that spins the blade and shaft as one. Does anyone know how to get the blades off? This is the second day of working on this in which my patients has worn thin. So before the blow torch or sawsall comes out I figure I'd ask you all first.

With the right tools--an impact wrench and a brass or wood punch if you plan to reuse the bolts without damaging the threads--it's a 1/2 hour job.

With the PTO disengaged and the tractor engine off, from above align the hole in the top part of the deck by the gear box with the nut of the blade and remove it. Use the brass or wood punch and a hammer and tap the splined bolt out. It's easier if someone from below holds the fairly heavy blade, and voila! it's halfway done! Intall the blades in the reverse. Lube the pivot and the bolt before installation that way the blades tend to balance themselves earlier when they fan out.

While you're under there be sure to retighten the main nut on the gear box shaft ....
