Getting lawnmower blades off

With all that site-supporter money, why the hell are you still cutting your own grass?!??

An easy way to get to them with a grinder is to use the tailgate of your pickup truck and ramps, pull the mower up the ramps to get to them easily, electric grinder and sharpen one side. I use that to touch up once in a while.

When pulling them off for a proper edge, block with wood and airgun always works. Engaging the blades helps too - AFTER the engine is off of course. Some folks use a file and bench vice - that's fine - I use a bench grinder. Have never balanced them, but if you want to ensure long life of your pulleys you can purchase a blade balance and sharpen the low (heavy) side until it's balanced.

I had to use a pipe wrench and a 4 foot cheater to get mine off....then I bought new bolts (obviously) and used anti-seize when I put them in.

Impact should take it right off. Wedging a board in there works also if you don't have an impact.

Yep, I wedged a board against the blade so that the blade was pressing against the board that was wedged against the deck underside. I suspect my blades hadn't been off for years and years.

If you can't get them off with an impact you can use a sharp chisel and hammer as a last resort.

I did professional lawn care for 18 years and now change/sharpen my blades weekly, NEVER used anti-seize.

Pros in the field sit on their butt and use their right food on the tip of the blade and use a ratchet to unbolt them, very easy and you get a ton of power on them.

change your grip, pressure, and speed. Breathing into its ear and telling it how hard and long they are helps too.

shoot it with some pb blaster or similar product, let it sit for a while, then hit it with an impact or breaker bar.

+1 good advice ...

If I took the blades off every week, I wouldn't use anti-seize either. That's not going to happen.

I coat my anti-seize with more anti-seize.
