Hit a rock and broke the blade on my brush hog squealer. It broke in the middle of the bolt hole. Can it safely be welded? I have access to one of those old Lincoln Tombstone welders as I know my mig cannot do it.

No. It's best to simply replace it. The blades are hard steel and are really difficult to weld.

They don't cost very much, definitely replace it! If you did weld it back, and it flew apart again and hurt someone, just think what an attorney could do to you???

you might want to consider replacing the bolt too if it was damaged

Not sure what width mower you have....(Part # for 5' is 7555, 6' is # 7556, and 7' is # 7557) Those will be hi-lift blades. Depending on how old your Squealer is, they may or may NOT have been equipped with hi-lift's from factory. They'll do a MUCH better job. Old style "low lift's" are no longer available from what I'm told. They are bolt in replacements. "Low lift" blades at one point were thinner/lighter than the part #'s I furnished (by just a couple pounds) You'll never know the difference, EXCEPT for the fact the heavier duty blades will hold up a little better.
As a bit of an experiment, I tried one set of aftermarket blades (from TSC) They didn't even come CLOSE to matching the life span of a genuine Bush Hog brand blade. Prices were pennies apart. Kind of a no brainer there....
DO NOT attempt to weld a broken blade unless you just want to live an (extremely) dangerous life. Just not worth the risk.
Last 3 sets of 7556's I bought were priced under $55 a set, inc freight.

You really can't use an older blade as a spare. they have to be the same to spin with minimal vibration. If you ever lose a small piece out of the tip of one blade, it will shake so bad that it wont be usable. Replace both blades and use the old blades as scrap metal.
I agree that welding it back together isn't going to work, but I have found the steel in my blades to be excellent for doing repairs or mainging something where I needed a piece of flat stock.

Talk about a cheap (and hazardous) idea......
Get the moths out of your wallet and buy a new one. It always helps to walk the area prior to mowing and look for hidden objects. I know that's probably an alien concept but it is good exercise.:laughing:

I have a welded blade on my mower right now. When it broke the dealer didn't have any in stock & I wanted to get some mowing done. I ground both sides & welded with 6011. Finished the weekend. Will get 2 new blades this week. They can be welded although I wouldn't rely on a welded blade as a permanent fix. BTW I don't have an irrational fear of liability but I don't allow bystanders either. MikeD74T

I'm not telling anyone what to do, but I'd highly recommend against welding blades to repair a blown out bolthole.
According to my math, 17,000 fpm works out to be over 190 mph blade tip speed. The fact that they can be welded doesn't mean you should do it. Folks, do not do this. Dis-similar metals (can be a good thing with proper metalurgy), loss of heat treatment condition...I don't have anywhere near FMJ's experience but I would take a WAG that the blades were nearly worn out and the metal around the holes was work hardened/fatigued which contributed to the failure. Just my guess.
A dealer without bush hog blades in stock needs to light a fire under the parts manager.
Dad went up today and just matched up the blades to a Brush Hog 67327 look close, but not exact. I will go up tomorrow and look for the correct 7556 blades 31$ a piece well worth it.
I know it's good practice, but how practical is it to walk a 9 acre field with 2 to 3 feet of grass and undergrowth in it to hope to find every rock. I have mowed this field at least 20 other times without an issue, and yes the moths did fly out when I opened up my wallet, but I quickly caught and returned them.:laughing:

Why would you want to weld, when a new set is less than $50.00?

Because not being able to mow exactly when one wants to is considered by many to be on par with a national disaster.

I like that part.. I have to remember that one for future use.
You're right about walking the fields too, rocks have been known to get shoved up by frost around these parts, so hitting one that wasn't a problem last year wouldn't shock me too much either.
I am a little shocked by the sarcasm in some of the posts on TBN these days, though. Like my grandmother used to say, "If you got nothing nice to say, don't say anything.."

replace it.. only viable option.
otherwise it's a missle waiting to launch...

DUNN, the 7327 blades worked fine, when I went up today the 7556 blades were too long. They were out of bolt kits, but the ones on there were fine. I had to do a little welding to the blade pan. Got it back together started to hog a little and the shear bolt broke for no reason (other than taking a hit so hard it broke the old blade). Checked the box and dad must have used the last one. Well down to the store to buy a shear bolt.

I always keep a extra set on hand so I always have sharp blades and in case of emergency another set! I messed up a blade mowing a property that was foreclosed I hit a pile of steel fence post that was covered over, and ever since then I have kept two sets
