It’s actually really important to keep your lawnmower blades sharp. Makes the whole process much easier, and the engine won’t have to work as hard.

[–] pearsaltchocolatebar@discuss.online 48 points 2 months ago (3 children)

Just make sure they're balanced before putting them back on!

Unbalanced blades cleans the inside of the deck though via vibrations

[–] WalrusDragonOnABike@lemmy.today 42 points 2 months ago

And sometimes the outside of the deck via through-deck action!

Where's your sense of adventure?

In the side yard, with my legs.

Uh does sharpening really do enough to unbalance it?

[–] ContrarianTrail@lemm.ee 12 points 2 months ago (1 children)

One or two times probably not but more than that likely will. Especially if there were major dents you grinded away. You can buy a cheap plastic tool to check the balance and then just grind away from the non blade side to balance it out.

[–] someguy3@lemmy.world 2 points 2 months ago

If you grind the same on each side without trying to get rid of any dents, it would still add up?

It can, yes. Remember these are rather heavy blades spinning really fast, so it doesn't take much.

[–] linearchaos@lemmy.world 1 points 2 months ago

It really depends on your definition of balanced and how bad someone is at sharpening.

The blades are torqued down on there, if it's a combustion engine mower, nothing's you do to this blade sans taking an inch off is going to make much more vibration than the motor will itself.

The biggest worry is that you put enough vibration into it too cause it to loosen the blade.

If you're even half reasonable sharpening you're just taking off a fraction of a gram.

It also helps keep your grass healthy, because a dull blade will rip the grass instead of cutting it. If your grass clippings look frayed, it’s because they’re ripping.

I usually keep a pair of blades. The one off the mower gets sharpened for next time and then I do an oil change + swap yearly.

[–] Addv4@lemmy.world 11 points 2 months ago

Yep. Grew up with my grandfather working on small engines (read:lawnmowers, either push or driven) and one of things he would do when doing maintenance on them was to sharpen the blades with an angle grinder. Mades mowing a lot easier and generally looks more uniform as well. The other thing was that it almost always is the carb if the engine has issues.

It's better for the grass too.

[–] odelik@lemmy.today 9 points 2 months ago (2 children)

I hate my grass. It needs to suffer, get over exposed to the sun, and never watered.

Can't wait to replace it with something not grass next year.

Until then, next time I need to cut it, I'm going to use a lawn mower blade supplied by the Chuck-e-Cheese kitchen to do the worst hack job ever.

[–] GoTeamBoobies@lemmy.world 4 points 2 months ago

Slowly replacing mine with a clover/daisy/fern fescue mix and it looks great and does so much better than grass

[–] And009@reddthat.com 4 points 2 months ago

Painless and smell less

[–] jewbacca117@lemmy.world 4 points 2 months ago

Absolutely! I had no idea until I mowed after that.
