I would sharpen my blade but its ruined it has a couple of big nicks on it, definitely needs replacing.. Nice trick coating underneath the deck with used motor oil, i should try that.
Besides having an uneven cut i heard if you cut your grass with a dull blade your lawn can catch a disease?

Great video, thanks. Though I had to laugh about "preventing the mower from accidentally starting." You're kidding, right? I have never been able to start a gas mower at all. That's why I own an electric one :)

@OffroadMadness1 Good idea, thanks.
Can you sharpen lawn mower blade with a hand file or is it just easier to go buy a new blade? I do not have any type of electric grinder just hand tools. Thanks

@mac777daddy Sure, a file works fine for sharpening a mower blade. It just takes a little longer.

@PunaniLicker69 Whether it's a lawn mower or a car engine, oil wears out and stops lubricating. Also motor oil collects all the dirt and dust and grit and corrosive by-products of combustion. Change the oil and the dirt an crud go with it. Old dirty oil increases wear on the engine's moving parts and shortens engine life. I change my lawnmower oil once a season but check out your owner's manual and see what they recommend for your mower.

Bent blades? Best to replace them.

I'm considering a 6" 1/5 HP bench grinder to sharpen my mower blade. Is this enough power for blade sharpening?

@coppertrail Yes a 1/2 HP grinder with 6 in. diameter wheels is just fine for sharpening mower blades. If you're only going to sharpen mower blades, wood-splitting wedges and other mild-steel tools then a conventional high speed grinder (3600 rpm) will be fine. But if you intend to also sharpen tempered tools (wood chisels, knives, etc.) then consider a slow-speed grinder such as the DELTA GR275. These grinders run at 1800 rpm and are less likely to overheat the tool enough to wreck the temper
