I had pushed the blades on my TC24D and the 914A MMM about as far as I could. I had sharpened them when I changed the oil earlier this year and I've mowed twice with them. Problem was it seemed like I was having to mow the grass twice and it was still leaving two stripes. So I decided I had to break down and go ahead and get new blades. I figure I did pretty good. I mow about 5.5 acres and I almost made it 4 years with the original ones. So I think I did it pretty good. I went with a set of high lift blades. I think they were $3 more than standard lift ones. A set of 3 were around $101 out the door.
You can see the difference in the blades in the attached pics. You can see how much of the old blade had worn away and how much more lift the new blade has.
