The DIY Way To Sharpen Lawn Mower Blades

!±8± The DIY Way To Sharpen Lawn Mower Blades

Is your lawn mower tearing of the lawn grass blades instead of cutting it? Does your lawn look like it has been eaten by a goat, in spite of being cut by the lawn mower? Wait; do not pull your hair by the root. Help is at hand. We will teach you how to sharpen the lawn mower blades at minimum price and effort.

Your Manual Lawn Mower - The Faithful Walk Behinds

Tools: The tools that your will require for doing this job are

You and your time of about 2 hours or less

A bastard file of about 12" long

A small crow bar to prevent movement of rotor of lawn mower.

A worktable will be useful for dong the job comfortably.

Procedure: You can use the following procedure as a general guide and make changes to it to suit you. Remember the procedure is not sacrosanct. The results are important, not the procedure.

If possible, remove the handle of lawn mower and place lawn mower on the table.

Secure it if possible in the clamps. If you do not have clamps, do not bother, secure it against any block, so that the movement away from you is restricted.

Fix the crowbar in the blades so that it will not rotate

With the help of the bastard file, file the edges of blades so that they look sharp. Work at an angle of 45 degrees

When one blade is sharpened, remove the crowbar and turn the rotor to work on another blade. Repeat the procedure until all blades are sharpened.

If you have a flexible shaft grinder in your DIY workshop, you will be able to complete the work within 5 to 10 minutes per blade. Make a template of blade profile before you start your work and compare frequently. This is necessary to ensure that you do not over cut at a place.

Safety Tip For You

While sharpening the blades ensure that the stroke is not too long otherwise, you may injure yourself.

Depending upon the lawn mower the procedure may vary. We have included general statements in this procedure; you would have to change the procedure slightly. Keep the maintenance manual of lawn mower handy if you have one.

Tools required.

Siphon hose and clean container

Heavy work gloves and goggles

Double-cut (medium-rough) flat file

Lumber scrap

Socket wrench set

Rubber mallet*

Bench vise or C clamps

Rotary blade sharpener accessory

Electric drill*

Screwdriver, or 1/4-in. rod or bolt*

Blade balancer

Replacement blade*

* Only if required

The list may look formidable, but tools are generally available with every DIY enthusiast.

Procedure:

The procedure is given for the simple single blade lawn mower, but the same will apply to all types of blades, whether single or double

Wear hand gloves and clean the engine and the gasoline tank from outside

Remove spark plug from the engine

Remove all the fuel from the tank of the gasoline engine. Use the siphon hose so you do not spill gasoline on floor.

Completely empty out the oil from gearbox if you have one

Invert the engine and have access to the blade.

Clamp the engine so it does not move and clean the blade area thoroughly

With help of a box spanner, remove the nut holding the blade. Usually the nut will be unlocked in the reverse to direction of rotation of engine. You may engage the screwdriver in the cooling fan of engine to stop rotation of engine.

If you find that you are using too much force to unlock the nut, put one or two drops of rust removing chemical, and try after 30 minutes

After you remove the blade, clamp it in the bench vise and sharpen it with a file or a grinder. Sharpen only the outer 2 to 3 inches. The area to be sharpened will be known if you see the blade.

Sharpen only to the required extent. Too much sharpening is not necessary. This is not the knife. It works at the speed of the engine

After sharpening, check with your thumb. Be careful not to cut thumb. If you have done sharpening before, or seen some one doing it, you will know what we mean by this.

Balance the blade with help of a small balancing tool on VEE blocks, or even on two foot rulers placed side by side

Refit the blades, refill engine oil and gasoline and test the sharpness of blades on uncut portion of your lawn

Safety tips:

Always use safety goggles and hand gloves when working with power tools.

Be sure to remove the spark plug before starting. Serious accidents can happen if you do not do this.

Long-Term Storage of Gasoline for Lawnmowers

!±8± Long-Term Storage of Gasoline for Lawnmowers

It's spring and the grass needs cutting. You get the gas lawnmower out of storage and look in the tank - it has gas in it. You pull on its cord to start it and after a few pulls, it sputters and starts but then stalls. How come last fall it would start so easy and now you are having one heck of a time starting it?

Well, you can probably blame it on the kinds of gas we are able to buy today. Ever since ethanol was required to be added to the gas at the pump, an unintended gas storage problem was created. If gas stands for more than a few weeks the ethanol will separate from the gasoline and in the extreme a varnish will develop which can clog the carburetor and internal parts of an engine. You might even have to take it to a small-engine shop to have it fixed.

Storage is not a problem when you are using gas in your car or truck because you probably are burning through tanks on a regular basis. But when you are storing gas in containers or over the winter in a gas mower or other small-engine-powered tool, the separation of the ethanol becomes a problem.

So how do you store gas properly?

First maybe it isn't such a good idea anyway. Only buy gas when you need it and burn through it - don't store it. Storing gasoline is not safe since it is inflammable, highly dangerous, and can act like a bomb if ignited accidentally or otherwise.

At the end of the lawn mowing season drain or siphon all the gas out of the lawnmower tank and then run the engine until it stops for lack of gas. In this way you can store the mower without damaging its gaskets or other parts of the motor.

The second method entails the use of approved-small-engine gasoline stabilizers which you can add to the gas in the tank. Some stabilizers claim to keep the gas from separating and creating problems for up to 24 months. It really doesn't matter in that all a lawnmower needs is about six months and you will be back to burning through new gas all during the grass-cutting season. Note: there are gas caps that can be purchased, that will contain the stabilizer, and add it to the fuel automatically. These work fine so long as you remember to periodically fill the cap, especially at the end of the season if you intend to store the mower with gas in its tank.

Long-term gas storage is a problem that can not only cause you a lot of aggravation - trying to start a gummed-up, small-gasoline engine, but can also cost you in the repair of an engine that has had its parts varnished by the stale gas. So before you put that lawnmower or other small-gas-engine tool away for the season, it is wise to take the steps necessary for the proper storage of gasoline.
