Question

How do you sharpen a manual, push type lawn mower?

Answer 1

Mine came with a special blade sharpener. You could probably buy one some where, or there must be a mower shop that offers the service.

Answer 2

with a file.

Answer 3

if you have a bench grinder then you can use that to sharpen it. otherwise you'd probably have to go a place where they sell mower blades and ask if they can sharpen it for you.

Answer 4

with a file

Answer 5

Take it to a saw shop......they know how to do the reel the best.........and you also have a bar on the bottom.....both have to fuction correctly........when they are working right you can not get a prettier mowing job around. They will grease and oil it correctly also........than take care of it...........I got lazy and got read of mine.......had 3 once......they are neat when working correctly.

Answer 6

take off spark plug wire first!!! remove blade use bench grinder or file to sharpen next put a nail or s***w into something vertical and put blade on it threw center hole if blade falls to one side quickly take some metal off that side you have now sharpened and balanced the blade

Answer 7

Put a stick between two blades so the reel won't rotate.

Use large hand rasp (file), run the rasp down the blade in long strokes (4 or 5 times) until sharp.  

Rotate the "reel", repeat for the next blade.

Answer 8

You use a file on the blades.

Answer 9

Reel mower we are assuming.

Get the tool. It is like a knife sharpener with a stone. (at that was the ones I have seen). They even call the blades on the reel mower "knifes".  

It is real hard to do correctly with a file because the angle is critical.

And a shop is not a good idea because of the labor unless the mower is expensive it is cheaper to replace.  

But you may get away with only lapping it. You use a lapping compound (grinding compound) then adjust the cutting bar that the blades cut against so they are rubbing slightly harder. Then coat the knives on the cutting edge with the compound then push the mower around on the garage floor to grind the knifes against the cutting bar.

You may have to collect the compound that comes off on to the bar and put it back on the knife edge and repeat several times. This will put a bit of an edge back on the cut.

A shop would both grind it in a jig made for that and then lapp it too.    



Good Luck.
