Today I changed the blades on our 5' finish mower ,
Let me tell you it was a Pain in the ASS !!!!!
First you have to figure out how to flip this Heavy Bastard on its Front, safely !!!
You do this by placing 2 big blocks on ether side , and take the front wheels off so the Nose can dig in , Then take the Bottom of the 3 point hitch loose and Pull forward Slowly

Then tie on some straps for safety AFTER Locking the Breaks !
Then Unbolt the Rusty ass Bolts !!!

That was Fun !!!
This is the Old blade Layed Over the New Blade , I think I got my moneys worth out of them
