On my Craftsman Lawn Mower, I have to raise the lawn mower or tilt it on it's side, and underneath where the blade is, there is a large drain plug. Take it off and catch the oil. This is a great time to clean the underside of your lawn mower and either sharpen or replace your blade.....Nothing cuts better than a sharp blade!
Firstly, to sharpen the mower blade, remove it from the lawnmower and get any rust off with steel wool. Clamp the blade down and run along it a file. For badly damaged blades, it would be best to take it to a professional.
Yes, well if it gets blunt... Why shouldn't you?
A lawn mower blade can be sharpened with a blade sharpner. Any major hardware store can do this for you. You remove the blade and clamp it to a flat surface. Then you use an angle grinder to sharpen the edge using the original angle as best you can. Safety glasses are always necessary as this is dangerous to your eyes.
I use my electric grinder with rough & smooth grinding wheels
What is better a high lift lawn mower blade or a low lift blade.
To sharpen lawn mower blades, carefully unscrew the blades from the machine. Use a putty knife to scape off any residue. Then take a medium file and stroke the edge of the blade evenly.
Get some leather gloves and a socket wrench set. Lean the mower over by raising one side so you can gain access to the blade. Be careful not to pour out any fluids. Work from the side of the mower that has the grass discharge (the right side). With something holding the mower at a tilt, grasp the blade with a gloved hand and loosen with the correct socket the nut under the blade that is in the center of the blade. As you loosen the nut, the blade will begin to lower. Be careful that you do not lose any of the mechanism, and notice the way it fits together. Just replace in reverse, but a tip is to put a little bit of grease (very little) on the threads of the bolt that holds the blade. Tighten well. I frequently take off my blade and sharpen it. Are you sure that it needs to be replaced? Can it be sharpened? Remember: "Lefty, loosy; righty, tighty."
With a file.
if its a rider you remove the deck, turn it over, clamp the old blade in place, & get a large wrench to fit the nut holding on the blade(s). if you have one, use an impact wrench. remove old blade(s) after you remove the nut. take off old blade and put on new one. replace nut and reinstall the deck. if its a pusher just turn mower on its side and use above instructions.hope this helped and good luck
A Razor, a lawn mower, and a rollerblade all include a blade. A razor has a blade. A lawnmower has a blade A rollerblade has no actual blade but it has the word blade in its name.
How do you change the blade on a Toro 21" self-propelled mower
