I decided to put x blades on my scag v-ride to reduce the clippings last month and it's been a headache ever since. We're noticing that there seems to be a lot of resistance when the blades are engaged. Almost like the spindles are rubbing on something and causing them not to spin as fast. You can feel it in the mower too. It just feels rough when you're cutting. Lots of vibration in the deck. As a result theres a lot of grass sticking up after the first pass. We have to cut everything twice. When they put them on the owner of the shop advised us to using straight blades on the bottom and gator blades on the top. I'm almost wondering now if there is a balance issue there. Are the straight blades lighter than the gators? They've had multiple mechanics look at it. They had there service rep look at it. Nobody can come up with an answer. I may just have to take these things off and go back to the single blades.
