Yep, an impact wrench is the only way to fly for mower blades. And for a DIY person, they come in very handy, in general.
How do you guys use a torque wrench when you don’t use any blocks of wood?I use an impact as well. I had a block of wood that I used before the impact came along.
I tried installing my blade bolts with the impact wrench on low as a test and the bolts were WAY over torqued.
