A Gardening Question

I have just bought one of these and it appears I may have to sharpen it.

blade

This is my current mower's first new blade and I was expecting it to have some sharp edges.

It does have chamfered edges but they are not sharp.

Am I correct in thinking it needs sharpening before fitting?

PS I also came across descriptions of balancing procedures. This is going to get interesting.

Re: A Gardening Question

Those blades don`t need to be "knife" sharp.... because they are not "cutting" against another blade,.. as in the "conventional" spiral bladed lawn mower... or shears... the work by sheer speed to smash through the grass/weeds etc.

 

after about a week or so, you may find that the edge has gained a few "teeth" from stones etc, that have been mangled by it....

Did you ever sharpen your old blade?

Re: A Gardening Question

After a great deal of searching I have come across the owners book and they recommend 1 of 3 options.

1. Replace the blade with a genuine item purchased from the manufacturer.

2 Take it to a service centre.

3. Sharpen the blade on a bench grinder then check the balance of the blade and adjust as necessary.

Option 3 is my way to go.

Thanks for your help guys.

Re: A Gardening Question

Option 3 is also the method I use.

Bench grinders are fairly cheap and have many uses.

Re: A Gardening Question

Like I said... no need to put a sharp edge on it....  it just hacks the grass and weeds as it is... if you really "want" to do some hard work... and save the cost of a bench grinder.... just use a "ba st ar d " file....  NOT avoiding the swear filter..

Re: A Gardening Question

I would never use an angle grinder myself, much rather put the blade in a vice and draw file.

Neater, safer, sharper, and less heat generated which can degrade the steel.

Why is a Bastar* file so called?

Re: A Gardening Question

From the French 'Batard' , meaning irregular, not conforming. Another miss-spelling ,pronunciation of 'foreign' words that were carried over from their original mother tongue that came to make up the English language....(French,German,Latin, Norse to name a few).

Re: A Gardening Question

The B****** files I have used have been course and shift a lot of material.

a "[-Censored-] file" is a file that is neither "coarse" nor "second cut."

I don't know if the replacement blade I have is heat treated as it has a full coat of paint so I can't see the bare metal.

I presume it hasn't been hardened or a file might not touch it.

I read of someone using an angle grinder (have one) to sharpen the blade with light strokes so as not to heat the blade too much.

Re: A Gardening Question

I don't think its anything special.

Each season I clean out the dead grass and the blade is a silver colour - and very blunt.
There is no way of cutting yourself on it.
