Gouged finish blade: Grind down or replace?

[Ursa Major]

Struck a rock while mowing with my JD 2305 and 62C mower deck. Can I grind this out or should I replace it? I realize I'll have to even out the other side if I do grind it. Just seems like I have to take quite a bit off.

Sharpening blades is new to me but it seems easy enough for the other two blades on my deck that were not damaged.

I have an 4.5" angle grinder, a low speed bench grinder and some nice files so I have the tools. Just not sure if too much would have to come off.

if it isn't too much $$ and you can get it fairly quick, I'd replace it. My $.02.

Just called JD. I have to buy the set, can not just get one blade. Oh well, guess I'll have two spares!

When you Deere gets to the age of mine you will just leave a gouge or two, unless it is a gold course green...I used to have them perfectly smooth and sharpened evenly..My bermuda cannot detect the gouge.... I have spare set of blades so when they get dull..

i would just sharpen the gouge, it will cut.

Good grief, some of you would shutter to see my blades. Mine look worse than that after the first trip down my driveway. Sharpen it and forget it, it’ll cut just fine.

Yeap, my working buddy here, will not touch his blades for his Kubota, he runs them and discards them. I wish they fit my Deere??.

Do compare it to the "good" blades though to be sure you havn't bent the blade

otherwise sharpen it and go. you'll find as time goes on, mower blades end up with alot of dings like that, that can be sharpened out enough to do a decent job of mowing

Good deal getting the impact wrench, don't know how I got along without them.

I would touch up the blade reinstall and mow.

Thanks, I did just that and its fine and not bent.

The blade only has to be reasonably sharp. Straight is a bonus, but sharpen the gouge and have at it.

They come from the factory straight because it is easier to make them straight than any other shape.

I think my blades are serrated from so many chips, but they still work fine.:laughing:

Ha, How true, Plus you would be surprised to find out they are different hardness ratings too.I still have good luck with aftermarket blades..

I wouldn't bother trying to grind away the blade until the
gouge is gone. Just sharpen around it, leave the ding, make
sure the blade is reasonably well balanced, and mow away.:thumbsup:

When wood chipper blades are taken in the sharpening place does not grind out all of the imperfections. You'd lose too much material.

Here is a suggestion that should get the safety police howling: I fill in the gap with weld and grind it back to the original. The tips get a bit of "soft" hard facing that can be worked (ground). It helps keep the shape longer.

We have very rocky soil here and the cost of replacement blades is prohibitive.

I would just run over it with a file and go.

I get my blades for a whopping $13 a piece. So, I replace my blades about June 1st every year and go. File down as needed.

Dull blades will turn green grass brown, especially if your grass is turf tough and thick.

I would touch up the blade, balance and then reinstall...
This is a mower, not a bush hog, right?

I live along a gravel township road and every winter when they run the snow plow I end op with a lot of gravel throen up in the yard. the small stuff isn't a problem but the occasional riverbiscuit hiding in the grass leaves my blades pretty dinged up. I usually wait until the second or third mowing in the spring before sharpening and just make sure the serrations are sharp too. At $70 a set I can't afford to replace blades 3 or 4 times yearly. I try to keep an extra set on hand already sharpened and ready to just swap out when some chucklehead tosses out a beer bottle or can out that I hit before I see it. Bottles sure will but a ding in a blade.
