LEARN HOW YOUR BLADE/BOLT/SPINDLE IS ASSEMBLED!!
For someone like me, who jumped from a Sears LT1000 to a Scag Tiger Cub, Im used to teeny blade bolts threading directing into the bottom of the spindle. Even after reading some posts regarding removing blades on a ZTR, I had fits trying to remove my blades this weekend for sharpening, in fact I failed miserably at it. I even consulted the manual, looked at the spindle assembly drawing, but somehow failed to grasp the fact that the blade bolt doesnt thread into the spindle!!
I was having the same "problem" as many others have posted about, on different mowers-- the blade wouldnt move, as I had it chocked, but when I would try to turn the bolt head from the bottom, laying on my side like a mad imbecile, pulling with all my might, the spindle assembly would turn, giving me fits!
I just took another look at the spindle assembly while pondering something Greg-ALC wrote about removing the nut on top of the pulley, and had a revelation!! Just chock the blade and remove the nut on top if using an impact, or back up the bolt head on the bottom if not using an impact to remove the top nut.
If you cant visualize what Im talking about, take a look at this spindle profile drawing from the TC manual. I believe many commercial ZTRs use this same basic setup. This post should be made a "sticky"....:hammerhead:
