Not sure how I never realized I posted this but here’s the links to the 2 products in here I use to balance and sharpen my blades. They’re not affiliate links, I don’t have a discount code for either of these companies. ⬇️⬇️ Model 5005 sharpener - www.allamericansharpener.com/5005 Balancer - www.magna-matic-direct.com/products/mag-1000-balancing-instrument.html

I have the exact same balancer and just love it! It moves so freely.

Excellent video. Very informative over a common, and frustrating occurrence for a lot of people.

Tire pressure plays a huge part

Where did you get that balancer and grinder mechanism?

In my long experience -- cuz I'm old-- for sure a bent blade can cause all kinds of problems including vibration that will ultimately take out a bearing. However, after considerable wear and sharpenings, the very end of the cutting tip gets rounded off and thereby can shorten the blade enough to cause it to leave ridges of grass in the lawn as you described. On another point of sharpening: if you are being as aggressive as shown, the metal will heat up enough to lose its temper and dull real quickly thereafter. It needs ongoing cooling by dipping in water when sharpening. Using your technique with the angle grinder, I can see how the blade would need balancing. By the time you are done doing that, you could end up with a toothpick of a blade just the right size to throw it on the metal garbage pile.

Good info complimented with lots of good feedback. I think the fine folks at SCAG got the memo on rigidity. Built like a tank on the 61” advantage deck.

Usually a spindle problem or worn out deck mounts but since I have a "politically correct" yard that consists of prairie weeds I usually don't sweat the small stuff. My "grass" is Indian Paintbrush, Dandelions, Bluebells and clover. Best of all I don't have to feed or water it. Thanks for the video.

Thanks for sharing but I put brand new blades on and still get this issue

It's not always a bent blade but a bent deck. All blade tips should be on the same plane. I've seen a blade tip 1/4" above or below plane leave a 3" or more mohawk on the lawn.

Your lawn, even with the raised lines looks much better than my yard after mowing. I find if I mow too low this happens (under 3") but if I raise it then it's not as bad. It's also hard for me to see it when I am mowing in the afternoon. I don't notice it until evening then the light angle changes and I see them.

I have the same issue after replacing both blades this year. I have the 5 star center holes on the blades. I found that the previous blades had distorted the star on the spindle. This caused the old blade to be hard to remove and the new blade would not go on the spindle until after I filed off the burrs on the spindle. At this point, only replacement of the spindle will fix the issue.

great video brother

i need that awesome set up

Noticed your sharping set up, where can I get one?

Where did u purchase those 2 cool gadgets? The blade balancer and that other arm you used with the grinder?

Where did you get that balancer,gadget to find bent blades. and grinder tool , awesome video

Would you get them tools to work with I'm not talkin about the DeWalt using I'm talking about the practice you got made up on your bench and that Mac 1000

That’s awesome. If you have a balancer, which no one I know does.

What kind of blade sharpening set up is that I love that guide arm set up

That's good. Unless you have a bent spindle.

Did you make that swing arm for your grinder, or buy it somewhere?

I've gone round and round with cub cadet. I've had two of their lawn tractors. Both left a strip around 8" wide of partly cut grass from under the left side of the deck. They both cut that way new from the dealer. The last one I put into the factory service center and they changed the blades and releveled the deck. Came back no better so I will no longer buy their products. I believe it's a deck design issue. At any rate I bought a badboy zero turn and it looks like a pool table smooth after mowing. Unfortunately after mowing for an hour I shut the mower off to walk a bit and then when I got back on it, it wouldn't start. Batteries hot but no ignition so I had to put a mower with one hour on it in the shop to be repaired.

If you have a bent blade won't it just mow higher or lower than the other blade(s). Wouldn't a stripe mean a bent spindle? I have the same problem and it's driving me crazy(short drive anyway)1

I don't worry about that stuff . It's grass and it's cut is my only concern.

Once , my tires had a small pin hole leak , so my tires wouldn't go completely flat , but just enough that it did leave unevengliness . Looks like you just have tire marks on your lawn , though !

I know one other thing that must be done is have the wheels all set evenly. That could also mess up a lawn and maybe even make the mower abnormally hard to push. I just hope that if it happened to someone they cut their grass too high and might be able to set it right as if nothing ever happened. It is one of those things you would want to fix if possible and never say a word about it to anyone.

Helloo Mr and where I found this magnet and the piece in the wood table for maintenance the blade

Appeared to me that if your blade may have been bent and would have been even more apparent if you checked out at the very end? I check mine by spinning each blade to see if ends align and are level to each other? Interesting equipment though, first time I have seen either apparatus?

I have a 3 blade zero turn mower that has cut higher on just the left blade ever since I bought it new. I've switched the blades around 3 times with no change. I've also measured the deck height and spindle height. Everything measures exactly the same from side to side. Still get the left cutting noticeably higher. Any suggestions?

Sam, how do you fix a similar problem with a reel mower?

I also have a 60in mower, I have put new blades, spindles, and belt, also had my deck re-leveled and it still leaving Mohawks like that.

Never sharpen your lawn mower blades razor sharp sharpen them at a 30° angle and the edge of the blade should be 25,000 radius.... The first quarter inch of your blade does most of the cutting... Make sure your deck is level from side to side in the front should dip down a quarter inch lower than the rear... That's The Sweet spot...😊

My mower mows evenly but then it just starts digging up the ground? I didn't hit anything and it was fine until towards the end of mowing? is that the same problem as the uneven grass in your video, just more extreme? Thanks so much

I'd like to know how to replace the deck lower cables on a Cub Cadet LT 1018, please. Just a site to get the info would be nice. Thanks

Where did you get the blade balancer from?

How did you fix the off-set in the middle blade?

So did sharpening the blade fix the problem or did you replace the blade?

How do you straighten out the blade

Unless I missed it, you never showed how to take that end out so it will mow evenly.

This is all well and good but what about the rest of us who don't have the fancy balancer? How do we check and fix our blades without this neat fancy tool?

Bearings in spindle let go and the blade shaft dropped down lower then the other blades

Back in the good old days on eighth of an inch run out on your mower blade was the limit of run out that was acceptable.... So don't be throwing. . away a good blades... I'd like you to know the standard of run out still applies to modern day so that way you won't misunderstand what I said... A blade can have a 1/8 inch run out..😮

Do you wire brush off the the grass that is stuck on the blades before you balance the blades. The sharping tool is an all American grinder and they work real nice. They have 3 models but one of them has 6 different degrees that you can set it at. It swivels at the base up and down. Put it in the balancer and find the heavy end, mark it with soap stone and start with that side so you don't take of to much of the blade and go from there. Use flapper wheels, they are more gentle than hard wheels and give you a flatter edge instead of a rounded edge.

Where does someone pick up that sharpening system?

So what you have to get rid of the Bent Blade and get a new one

that balancing tool you use reminds me of a bicycle wheel truing station. it seems great for making sure your blade is not bent but how does that balance the blade? The tool that I have is much cheaper but it just lets you place the blade on a flat surface and then you can let gravity tell you if one side is heavier than the other...

Unfortunately you didn't show how to straighten the bent blade.

What if i noticed my mower cutting low on the middle blade and leaving the strips of grass so I got new blades and it’s still doing it

i look at a lawn like yours and wonder what would bend your blades. something much easier and faster is check tire pressure. you probably have a flat tire. 9 out of 10 times it is a low tire not a bent blade

My lawn looks terrible and I have uneven cuts all over. I guess a small engine shop can bend the blades back?

Uneven stripes are caused by dull/bent blades and or uneven tire pressure

Wow, does it really matter? Especially if the average person doesnt even notice it. Looks great to me.

killer graphics for your logo.

my JD rider does that and I was told I had a bent deck.. I got it from home depot and they said it was a return after 1 week. Well , bent deck will not give an even cut!

With a bend like that wouldn’t you have heard when it got damaged?

Uneven tire pressures will cut unevenly also. Thanks

Pennsylvania accent fo sho

You never showed us what repair the bent blade needed. Do they fix the blades or do I buy a new one? Otherwise, what was the purpose of the video?

seems to me that grass residue and rust should be removed before putting on balancer to check for bent blade or balance...

I just bought a wright stander b 36 cut like this they think im crazy . 8k a cuts like shet.. trying everything... that b. Something if its a bent blade... im about to sell it with 10 hrs... never buy a wrights mower ever agin. But they looked at it again. .. think they would of coaught that... im checking that. Thanks man.. ? You cant fix bent blads just get nrw ones...

Wow, a $200 blade balancer.

The way I seee it is , if it freaking cuts! Use it

I’ve always noticed that in my yard but I just thought the yard was uneven

MOST of the uneven cuts are because your land is not flat. There are dips, etc and if you use a riding lawn mower then this happens more often. A push mower has less space between front and rear wheels so the cut will be more even than riders. If your blade is bent then you'd feel a vibration.

No excuses when a man cuts a yard he will do it right

Noooo sound..

Nothing wrong with that yard. Its just grass. Way to many important things to worry about.

If you don’t start the engine it won’t mow like that.

Git a John Deere mower z370R

Shaft is bent 😂😅

If u drive slower, itll cut more evenly.

Tires deck not properly adjusted dull blade an or bent blade Shame after all that you put a grinder to the blade

People are getting lazy. We've forgotten how to do things by hand.

All that safety equipment and no gloves.smh

That’s not enough bend to cause a issue

Move your finger so I can see what you are talking about.

If your blade was bent it would vibrate so bad and ruin your mower even the slightest bend

WTF was that fix??

Absolute rubbish about a bent blade leaving ridges! You are using a ROTARY mower,ergo the blade/s rotate in the horizontal plane, therefore the low AND high side of the blade/s both pass over the area of grass multiple times as you mow. A bent blade will result in an uneven cut if you rush the. Mower! II too am in my 70’s and have been cutting grass for over 50 years!

That’s bs

big deal.....go in & have a beer!
