Which blades?

[Teachu2]

Check the thickness at the hub mounting point, they wont wear there so whatever they were originally, they will still be. My original Ferris mower blades are a bit thicker than Oregon blades.

Oregon produces a variety of thicknesses that fit my mower. The G6 blades are thicker than the G5, etc.

I always use orange blades-last longer.

I was buying the G6 blades thinking that since they where more aggressive, they would cut better, but then I read a post somewhere that suggested that wasn't true. It got me to thinking that the best cut I ever got out of my mower was with the factory blades, so I switched back and have to admit that they leave a much nicer cut then the more expensive, heavy duty Gator blades.

Best prices that I've found are at this site. Replacement Blades

I buy the two pack for my tractor. I never sharpen them, I just use them for about three months, then put in the second set for the rest of the season. That's also when I clean out the underside of my deck and do my maintenance.
