you need to turn the mower over..take a ratchet and take the blade off take it to someone who sharpens blades or knives. Get your oil at walmart bj m

Most important- if the blade is on a gas mower and you are removing the blade or working on the underside of the mower.Remove the spark plug wire- to prevent the engine from “Kicking” and possibly hurting you.
To sharpen the blade, only the last 1/4 inch actually cuts. 30Wt oil can be bought at just about any store.
Good luck dennis o

File is the best way to sharpen a lawnmower blade.

Lawnmower blade balancers are available from small engine repair shops.

One should be used each time you sharpe the blade to make sure it is balanced.

An unbalanced blade wil cause vibration in your lawnmower which could lead to costly repairs.

As others have mention, SAE30 oil is available at service stations, hardware stores, some grocery stores, etc.

Good luck John D M B

When i sharpen my lawntractor blades, i remove them from the deck , one at a time. I follow the original blade area , using a handheld grinder ( a bench grinder will work as well) - i start on the face - make sure theres no dings in the blade, i straighten out the face first, then go to the angle cut, lightly with many passes at the same angle, contrary to belief, the blade doesnt have to be razor sharp( good for cutting off fingers when replacing) , just to a near sharp, slight flat end.
Id suggest if the blades are bent, or have too many deep nicks, replace them. If not confident sharpening, replace them and take them to a shop and have them sharpened for spares. Clean the blade bolts/nuts/surfaces, use a slight bit of neverseize on them, so they will come apart easier next time. Id suggest checking the deck minumum of once a season, more the better since it gets so much abuse. Maintenece is the key to longevity.
SAE 30 motor oil is availible at any auto parts store,Walmart, Kmart, ect - use a name brand type tho. Id suggest changing the motor oil at least twice a season, more in dusty/dirty situations ( same goes for aircleaner elements).

best results are with a large flat file

tilt it over muffler side down…
follow the angle of the blades edge with the file
(like knife sharpening)

a better way is to take the blade off, and clamp it down….

angle grinders will work but…you can screw it up pretty easy and make the blade REALLY unbalanced. loujitsu1978

I use a file to sharpen the blade. Straight weight oil, should be available at gas stations, or oil change stores, auto parts stores. good luck. fordman
