Blade sharpening.

[kevinj]

Hi...
I'm new to this site.
I'm very surprised that it's not very active.

However, my question is...
Is there a set angle that blades should be sharpened at ?
Thanks for all your responses.
I'll check back tomorrow..

Kevin,welcome to lawnforums! Im not sure if there is an exact angle,however i try to keep the angle that new blades are set at from the manufacturer.I use a 6" grinder,so i just try to keep it as close as possible to original.If you have a dedicated grinder im sure it would be easy to set it to the exact angle you want.

Most of the studies I've read from manufacturers suggest a 30 degree angle. In their studies manything were factored in blade sharpness and longitivity, productivity, less tearing of the grass blades, and many agronomic benefits.

You are correct, it is a liittle slow here. How ever the info deliverwed here is very accurate and reliable and worth stooping in from time to time to review.

1 time per year when I buy new blades I set the angle to the new blade on my grinder, then just try to keep it as close as possible, I have not noticed much difference with the angle affecting things as long as they are kept on a 90 degree angle at the tips.
