| Sharp Mower Blades | |||||||||||
|
Ever see a lawn, otherwise green, but with a slight brownish hue? Look closely at the grass blades next time and you'll see they've been torn instead of cut. And the area of blade between the little tears is brown. Always mow with a sharp blade. The blade needs to be sharp enough to cut, not tear, and that is generally between 10 and 20 lawn mowings depending on typical sizes and conditions. Wet grass and thin lawns with a lot of dirt or sand showing will dull a blade immediately. Dry, nice lawns will prolong a sharp edge significantly. ILG has one customer who insisted we begin his lawn mowing with a newly sharpened blade set and then stop half way through it and put on another set. I wholeheartedly agree with the former since I've seen the benefits, but after some discussion, he agreed that the latter was a bit of overkill. However if the grass is at all damp, we will change blades halfway through this lawn. ILG uses a bench grinder to keep our blades perpetually sharp. We find that mulching blades will withstand 6 - 8 sharpenings before being worthless. Standard blades should hold up twice as long. A homeowner should always have one spare, sharp blade set around. That way it can be used while the dull set is at lawn mower retailer (not a chain store) being sharpened for $2 - $4. If based on the above you suspect you've been mowing with a dull blade, I guarantee you a somewhat nicer looking lawn if you'll sharpen it.
