Missing blades is streaking, uneven cut is higher on one side than the other.Wil22 said:I would like to know the anwser to that question also. After I installed new blades I notice I too miss a few blades. I thought I read somewhere, even with good equipment you will miss a blade and have to go back.
I have a Honda mower with new blades and it miss cutting sometimes, and it's less than a year old.
Yes LOL!Mo Green said:No........it's caused by uneven grass....LOL.
I'm not sure what kind of mower you're using, but I've never seen a Scag, Exmark, or Encore deck bend. Now as for Craftsman, or all your other Wal-Mart mowers, they bend at first use. As for missed grass between two blades, that goes for the same. Blades are staggered so that doesn't happen, on high end commercial mowers. In fourteen years of mowing I've only seen missed grass between blades once, the spindle came loose and the blades wore against each other, and noone bothered to say anything about a strange noise.?Nobody said:MarcSmith is correct.
I my experience the most common cause of uneven mowing is a bent mower deck. It will be, most likely, lower in the front than the back. It is caused by the attachment points becoming bent forward on the upper part of the deck. Take the deck off and use a heavy hammer to pound them back in to the proper position. It may take several tries. Use a bigger hammer if you must. Keep a welder handy. Work on a flat surface and measure the blade height at several positions, but mainly front and aft. If you have adjustable front supports you don't need the hammer for the first few bends.
Decks get bent when something hard is hit and stops the whole machine from moving forward. In other words, the deck stops the machine from driving forward.
Bent blades are perhaps the second cause of the problem. Make sure you get the correct blade for the mower and balance them.
Dull blades will just cut ragged and push the longer grass/weeds over.
Missed grass blades between two blades is common. Sharp and newer blades help. The best mowers are single blade mowers but they don't have the width. As with everything it is a compromise between speed and quality.
