Locktite on blades ?

[jeffyr]

In another post someone mentioned having a blade come off because locktite was not put on one time.

Does anybody put locktite on ? The convex washers and lockwashers are enough to keep the bolts on......no?

I never heard of doing the loctite thing on mower blades. This is my 8'th year at this, and never lost a blade.

The correct blade and washers must be present and if a guy wants to be safe he will get a torque wrench. But before all of this he will sit down and read the owners manual to see the torque setting and procedure for replacing blades.
I have never lost a blade or had one come loose but I have heard of people doing less than smart things to their mowers, loctite is another one of these.

I agree with scott! somebody, somewhere aint doing something right if they are losing mower blades! AAAAAGGGHHHH!!! THERE GOES MY LEG!!!

I do the opposite, I lubricate my bolts and clean out all the nicks in the threads with a tap and die so they turn in and out real easy. I have never had a bolt come loose. My guess is, this member hand tightened a bolt forgot to tighten a bolt with the wrench and when this member shut the blades off, it unscrewed.

thats what i do eric,you must be doing something right
later:D

Had an edger blade come off once.........well not me........somebody that I know............yep..........flew off and stuck in the side of a Church Van!:angel:

Loc-Tite is a chemical used to prevent bolts and nuts(nuts and bolts) from loosening.........but not when you want to remove them every day or at least every other day. Ain't never put nairn on my mower blades, don't reckon I ever will..........til they come up with a blade that lasts the life of da mowa........I wish.

[racerdave]

Homer, be careful what you wish for, they may reduce the life of the mower to match the blade life!
loctite is a very good product, and it would work great for mower blades (nutlocker) but the setup time of the chemical would be up in about the same time that you would be ready to pull the blades again. LOL

I've never heard of a mower blade coming off or even working loose for that matter. Seems like even if it did, the blade would stop turning with the spindle and you would notice it long before it came off. Even if you hit something solid in a lawn, the blade seems to get knocked tighter, not looser. I could be wrong though, Russ

[Richard Martin]

You hit the nail right on the head Grassman. I did, for some reason, have a blade come loose last year and all it did was spin. The danger in blades is when they break while they are rotating at over 200 mph.

[Charles]

Ya I am with the rest. I grease the bolts and air wrench them on. Never ever had a problem with them coming loose. The bolt only may come loose when the washers flatten out. The washers flatten out once a year for me but are the least of my worries

How would a person change there blades and sharpin
there blades if they had LOCKTITE on the bolt.
I so much don't understand this, unless it was a
home owners 21 inch mower.?? That never sharpin
there blades.:eek:

Good post.Been using Anti seize on my push mower blades and car lug nuts.Never a problem and I've always double checked torque.Where any bolt can fail is after is has gone through too much loosening and retightining because a bolt holds its torque by stretching slightly so I like to replace critical bolts every so often.(Auto parts store)Aircraft fasteners are checked for stretch both for torque and replacement.Most auto suspension is grade 5 that will bend under impact(3 marks) because it is less brittle than grade 8(5 marks).
Dorman and ARP USA bolts seem good,beware taiwan/China stuff.Had some (Gorilla)
flashy chrome lug nuts starting to go bad before.
Loctite I know of-Blue medium,just an added snap to unbolting,and Red-Lethal
Cannot undo connecting rod cap bolts unless you use heat.

Put NeverSeeze on the threads after a blade change. The nuts spin off easier, yet will stay tight as you mow.

[PrimeGreen Lawn]

I think we've made our point. Now are you gonna still Loctite?
:rolleyes:

Put loctite on your bolt and you will have a hard time dis-assembling the blades at the next sharpening.

Think about it, you will back it out a little with the blade locked, and then the blade will free spin. Now you have no way to lock the blade and the other two blades will rotate through the belts as you turn your wrench.

[racerdave]

Let me make this perfectly clear.

I would not put Loctite on a blade bolt. What I'm joking about is the fact that if you did use it, and you mow full time, the stuff would not be at strength until about the time to sharpen the blades again.
oh well...

oh and they make "nutlocker" the green stuff. works like a lockwasher.

I use the meduim Loctite "the blue stuff" on things that tend to vibrate loose. And I use the high strength Loctite "the red stuff" in heavy duty areas where a loose fastener would be catastrophic to my equipment.

If you use any of "the stuff" make sure you use the degreaser cleaner form loctite. Or you are wasting your time.

I never used it on blades......my post said that someone else posted that they did use it and nobody disagreed or said otherwise. I agree with all the good reasoning said here---mostly that it wouldn't cure by the time we changed blades anyway.:)

[BUSHMASTER]

I use anti -sieze,if your bolts are backing off check the tourqe spec on the blade bolts and check the balance also. :blob3:
