Help!! Rotary Cutter Blade Assembly Removal

[shesh]

Hi, the gearbox on my rotary cutter is toast. I can't get the blade assembly off so I can remove the old box. Details in this video.

Has anyone seen this style of blade assembly and how is it removed?
Thank you!

Should have a access point from above the deck to unbolt retainers holding the blade pins in place

It's probably a tapered fit, get yourself a two jaw puller, put the bolt in loose (at least a couple turns out and keep loosening it as it comes out) for the center bolt of the puller to push against and just go for it, put the jaws on the step of the external part around the shaft, easy peasy.
