Trying to replace the pulleys. They're pretty rough and eat up the belt.
Can't remove the retaining nut because turning it just loosens the blade.
I've never seen blades attached this way where there was no locking mechanism like a channel they fit into or a keyed shaft they fit on.
Once the blade bolt is loose there is nothing to torque against to remove the pulley retaining nut.
Am I missing something here?

I am thinking a strap wrench around the pulley then use an impact wrench to remove the nut on the top. Do you have this mower mounted on your B7100? I just purchased one to put on my B7100 hst. Wondering how much you needed to change the mounting brackets.

Hadn't thought of using the impact wrench. I'll give that a go.
My tractor is a B7100HST-D and I got it used with the deck attached.
Doesn't look like the mounting hardware was changed.
I took the hardware off that connected it to the 3-point hitch for raising to make it easier to work on. I just leave it raised on those rear hanger links. It cuts close enough for my purposes like that. I switch out the clevis pins and replaced them with bent hitch pins that are much easier to work with.

Tried the impact wrench after re-installing the blade and torquing it down using just the blade as a stop agains a 2x4.
Worked Great!
Thanks for kicking my brain into gear.
