These are 3 separate blades for a 21" Toro Super Recycler by the way.

Yup they look like Lawn Mower Blades!!! LOL :D

What do you use to sharpen them and how often (hours)?

When I sharpen mine I try to keep the whole angle not just the tips, I just think it gives the grass a cleaner cut, but that is just my option as I am a newbie.

I'll give details after I've heard more comments - good or bad.

I guess I never said what I do. I have a 8" grinder that I use and lightly clean up with a file. I sharpen/ change out every 20 or so hours of use on my 54" zero turn and switch out my walk behind every 2 weeks I would guess 10 hours or so. Some times it will change if I have an odd clean up job or feel they have taken more abuse then normal.

Input would be appreciated!

I am actually doing them tomorrow and will try to remember to take pic.

I need to do mine. I normally have it done with the oil change but noticed it needs it by looking ay grass I cut. Thwy are gator blades anyone even know how to sharpen them? I was just going to get an extra set and slap them on in the mean time.

I cant really see the leading edge profile from the pictures , and to me thats the most important part .I dont leave my blades looking like those though ,my final cuts are the full width of the bevel in a straight line ,then I run them on my synthetic wire wheel to remove the burrs ,not sure if it makes any difference [my method probably shortens the life of the blade if anything] ,its just the way I have always done them .

OK. I can't take it any longer and I can't believe I haven't been flooded with "that looks like CRAP" posts. (Maybe I should have posted on that "other" lawn site)


I DID NOT SHARPEN THESE.

I PAID my dealer to sharpen them.

They look like heck to me, but honestly, I don't know what a good, sharp blade should look like.
I've only been doing this since last year essentially, and all I've done is use a file on them. That said, I never put 6 different angles on one blade. Sheesh! To me, these look like something I would have done the first time I tried using a grinder.

The dealer used a grinder of some sort. I did see him balance between "grinds", but I dunno... that just looks like a bad job to me.

Am I wrong?

To be honest, I wouldnt have paid for them... Id have demanded them to be resharpened and a new blade to go with them for the crappy job.

The blade should be sharpened full width, not just the tips... SAME ANGLE/PITCH, not some half assed hack job.

My 4 year old could honestly do better. No offense...

But if my dealer ever brought those out to me, Id laugh them right back to the grinder after I called the owner over to look at the hack job they did.

Correct me if I am wrong, but looks like the "blued" one of them as well, which will make it lose the temper and not hold an edge more than one yard...

yep he is correct thats a hack job all day long...i would take them back to the shop and show the owner and demand a re do on them for sure ...

I think they look pretty decent actually, as long as the balance is correct it should do the job well!

They look like crap to me I would not be happy if I paid someone to sharpen them and thats what I got back

It looks like someone used an angle grinder on those not a blade grinder, I would agree that the angles seem a little off and they should have taken them back farther but I have seen much worse. As for the tempering they are push mower blades they will blue easily if you expect a dealer never to do that you should not have them sharpen a lightweight blade.

I was going to ask how you check for balance on the blade after sharpening, but then I saw you had a dealer do it. But then.... I thought it still might be a good idea to double check them.

I found some pics of nice sharpened edges to help with comparing.

They will cut fine for a while by only sharpening the cutting edge until you have lost the angle completely with only sharpening the cutting edge. Then they will cut like crap and no shop will take the time required to sharpen them correctly. They will tell you it's time for a new blade and you would only have gotten a 1/4 of the life the blade should have gotten.

Good for the shop, bad for the user. :-)

Here is what they looked like minutes before I took them to be sharpened...

I had used a file to sharpen them.

#1 is the original blade from the start of last season.
#2 was purchased midway through last season.
#3 was purchased at the beginning of this season.

I'm still learning, but from everything I've read, you're supposed to keep the angle consistent across the lengths as you go. I did not put an angle on the flat, bottom side - just lightly rubbed the file across it to remove any tiny burs from sharpening the top side.

I don't see how the hell I'm supposed to resharpen the blades now that they are in the shape they are in.

You should be able to fix them on a blade grinding machine yet. I would be looking for someone new to be doing my blades from now on

OK, so the general consensus is that I am justified in voicing my concerns over the job done?


I thought they looked like a monkey did them, but I've never actually SEEN a sharpened blade, so I wasn't sure if it was something worth "complaining" about.

As far as I'm concerned, they destroyed them, as I can't even follow the correct angle if I try to file them myself.

Those blades arent really that light... They shouldn't have blued the blade... Period. I could see a LCO owner maybe bluing it, or a home owner... but the shop that does this on a daily basis... This is out right stupidity.

Sure you could just sharpen the tip... not follow the true angle... But the blade is so much thinner then, will not hold the proper edge. Thats why they sharpened it on that angle in the first place when they are new.

With the money I spend at my dealer, this WOULD NOT fly... Point blank.

Think about this for instance... Would you take your freshly sharpened chainsaw out of that shop with bluing on the chain... No, I doubt you would. Same deal with a mower blade.

Inexcusable lazyness is what this is...

complaints are well worth it.

Matter of fact, they should sharpen those same blades at no cost and throw in a new set.

If you do not complain then they will think you are just another guy they can scrw over with a quick job.

If you do, then they know they can't pull one over on ya.

Yes your justified in voicing your concerns over the bad job, and you can ask for the new blades but I would not expect that you will get them. The best your going to get is hopefully they will fix them and do them the correct way.

These are mine sharpened. I actually didn't use the grinder this time. I have a attachment for my dremel that works great, well at least I think so.

Only have a few hedge trimming jobs tomorrow, so I'm taking the blades back in.

I'm going to ask to have them resharpened and have the blade I just bought at the end of March replaced since there wasn't anything wrong with it until it was "sharpened". (heck, none of them were all that bad actually)

I tried touching up the one on the mower with a file today, as it didn't seem to be cutting well. What a joke - no single angle to follow thanks to the "sharpening" they did.

UPDATE:

I went to the dealer today. Unfortunately it was really busy and the owner was with a customer, so when it was my turn at the counter, I presented the blades to the guy who was available and asked "What's your opinion on the way these were sharpened?"

He looked at the one on top, squinted his eyes as though he was wincing, and said "Did WE do that?"

I told him that I normally just run a file along them, but when I tried that on the newly "sharpened" blade, I couldn't even find the ONE angle to sharpen it.
"Can you give me a minute, I can get these fixed up for you", and off he went, shaking his head in disbelief.

When he returned they were all looking much better. (I'll post pics later)
He then stated, "I know who did this - new kid in the shop - he's gonna hear about it on Monday." Hopefully he does say something.
Oh, and he told me they weren't balanced very well either.



I still plan on stopping back and requesting to have at least one blade replaced - the one I just bought last month.

HEDGE: I would take the worst blade you have and practice on perfecting your grinding skills.
I use a 8" bench grinder DELTA 1/2 HP...This will save you crazy $$$ & time...
We sharpen blades everyday...

Wow! How do you get blades to look like that!? I'd like to know. Thanks.
