How often should I have my mower blades sharpened?

I recently purchased a new zero-turn mower and I was interested in knowing how often I should have my blades sharpened if I am going to be mowing multiple residences all summer long. Probably around 30 yards every 2 weeks or so for about 4 months.

    You need to sharpen the blade ( or blades if you have more than one on the cutting deck) about every 15 times you cut a half acre. So if you were cutting 7.5 acres you should sharpen the blade every time you cut the lawn (since there are 15 half acres in 7.5 acres). This will speed up the rate you cut and reduce the amount of gas you use because you will cut faster and it will require less energy to cut the lawn.

    Probably the best reason for sharpening that frequently is a dull blade will result in the grass drying out quicker and therefor a browning lawn. A sharp blade helps keep the lawn green and even.

    I recommend having at least one or two extra blades so while you are using the blade on the mower the other blade can be sharpened at your leisure and installed readily when you are ready to change the blade.

    Of course if you hit some large objects such as small rocks or sticks you may need to change the blade sooner than that.

    I recommend you copy No 1 as he is right on the money for the brown grass definitely is a sign of need to sharpen the blades. Keeping extra new ones or used (sharpened) is very wise so that you never get in a pinch to put on others if you happen to hit something. Do take the extra’s with you and the tools to remove and replace while at site ..but be very careful to un hook whatever starts the engine before messing with blades. You could lose a hand or fingers if you don’t. A guy picked up his push mower while running and managed to cut his fingers off while attempting to mow the top of his hedgerow…Sometimes I wonder if he thought first about climbing up on top of the hedgerow to mow it..since the other idea was just as stupid.
