Mowing Blade mounting bolt

[Chugbug]

Getting the MMM ready for spring. Does anyone know the size of the blade mounting bolts for the RCK60B-23BX? Putting new blades on this week. Also for those who have the MMM is it ok to use an impact wrench to remove and install? Thanks for the help

Definitely use an impact to remove, makes it very easy...
Always start bolts & nuts by hand, to insure your Not cross threaded... then you can use an impact to set them, But do Not hammer them on.

Any idea on the size of the head of the bolt I'm thinking 30mm

The ones on my BX2660 uses a 30 mm and I use an impact to remove, but tighten with a torque wrench at 80 foot pounds. I know some who use an impact successfully, I just prefer t use a torque wrench.
