Blade Bolt Torque

Somewhat scrub question here, but I was flipping through my new TTHP manual and it said the bolts holding on the blades need to be between 115 and 120 ft-lbs of torque. After I sharpen my blades and go to put them back on, is there any way to determine how much torque is on them without having a torque wrench (like the nascar pit crews have ). Also, do you guys even follow that or do you just tighten it really tight? Any suggestions are greatly appreciated.

I always use a torque wrench. You might want to just bite the bullet and buy one. It's a very good tool to have.

I use a torque wrench on my Dixie at the 90 foot pound spec. It is not required to twist on the blade bolts with an impact until the bolt won't go any tighter.

Nascar

Isnt the reason the nascar guys not needing a torque wrench because they regulate the air to the guns at a certain psi, same effect as Torque Setting ?

I have to block off the blade in order to tighten the bolt or it will just spin. Are you tightening with the blades engaged to hold it? Doesn't it still slip? I don't torque it just give it a good pull.

While I was on my union break I looked in a JC Whitney catalogue. They sell a 1/2" drive Torque wrench for about $25. If this is all you would use it for then why not go cheap.

The bottom of my spindle(on an Exmark) is notched so I can use a 1" open ended wrench and brace it against various parts of the deck to remove/install the blades.

I was fortunate to have a torque wrench already installed in my elbows when I was born. Comes in real handy. When I tighten my blade "bolts", I seem to know exactly when to stop. Every time I loosen them, there never too tight, never too loose.

I can also adjust the built in torque wrench so that it doesn't impeed the performance of my beer drinking.
