Mowing deck bolts

[JOHNTHOMAS]

While I have my deck off, I want to replace or actually get a spare set of blades so can sharpen one set when I decide I have time and then replace them when they dull, just rotate them. I finally tried my air impct wrench on my tire removal and it's great so I want/need to buy a socket to fit the bolt holding blades on. What size socket? It's also opposite of righty tighty and lefty loosee isn't it?

Since no one has answered you yet, they look the same as on my B3030. They take a 30mm socket & they're right hand threads.

I use a 30 MM for my 60 " deck too.

Yes, 30mm on my 60" deck, bought it at Autozone.

Thanks guys. 30MM it is. Right hand threads mean opposite of most threads, right? Means I have to turn these to the right to loosen them and left to tighten them?

JT,

They are normal Righty Tighty, Lefty Loosey.

Interesting... here's what the red version looks like. Notice the smaller nuts (24mm) on blades....

You're right-- air impact wrench darned near compulsory to remove those nuts!

I actually use a couple of 1/2" breaker bars to change blades and of course a torque wrench. Tighten 75-80 foot pounds. I don't even bother to take the deck off.

Decks off for fluids and filters service, don't have breaker bars or torque wrench and do have air wrench. I'll be more careful of what I cut with my new blades while I sharpen these old ones and maybe won't have to change them again until next service when deck will be off again.

Since my wife learned not to "mow gravel", my blades make it through a whole season usually, but for a while...

Using an impact wrench sure is easier since you have the deck off.
