I was wondering what type of blades everyone uses and when you decide to go buy new one (when do you know that they are worn out)?

Hi Andrew

This all depends upon how much you cut per week.

If you cut everyday (5-days weekly) you should sharpen the blades every other week. grease as much (I check and do it weekly).
This will prolong the blades by keeping them sharp dont round the tips keep the correct pitch and balance. NOTE: A unbalanced blade causes viberation and can make things loosen and cause even more maintenance issues with pullies and other parts.

So to answer your question Depends on how much you mow, for ex. avg home owner cuts every 5-7 days for 35 weeks and at with a avg lawn of 5000 sq ft, you would want to replace the blades every 4-5 years.

For me I would change every 2 years with 100-120 cuts per week for 35 weeks each year and that is sharpening them every other week.

The less foreign object you hit the longer they last, stop and pick it up takes a sec and saves you money in more ways than I can list.

Hope this helps

That's the truth.

This reminds me of one time after I sharpened the blades on a three spindle Scag walk behind. The first job the next day was a two acre yard. This customer was very finicky about her grass.

When I finished her yard, I looked back to check it out and noticed there were alternating high and low stripes in the grass. Oops, I must have been half asleep when I replaced the blades and I got the spacers mixed up on the middle blade. Ughhh!

We had a good laugh and she was kind enough to let me wait until the following week to even it out.

So how much of the blade should there be before it starts to get to where it bends in the blade? I sharpen (try to) everyother week. thanks for everyone's help, i guess its time to just for over the money and do it, to me they look like they should me replace.

You don't have to sharpen them if they don't need it. If you just sharpen them anyways you are taking off a layer of metal basically that doesn't need to be done. Causing your blades to wear out faster to.
If you arent doing that much mowing they might not need sharpening every other week.

We have two sets of blades for all our mowers. When the set on the mower needs to be sharpened, we take them off and immediately put the other set - already sharpened - on the mower. Then we sharpen the set we just took off and hang them up to be put on the next time.

Im using high lift gator blades, nothing else compares! Try a set the next time you need new blades and you will be hooked.

Does any body on here have the blades on their mower so that if you looked at them it would look like a + sign?
2 blades crossing each other.
I can't remember what it is called specifically.
Maybe Kieth knows what I'm talking about.
I read that it really steps up the cutting performance.

That's called double blading.

I have never done that but his guy is a believer:
