Probably a good idea not to mow the rocks. Besides being hard on the blades, you can fire one out the discharge chute and kill a ground hog 50 yards away. :ROFLMAO:

The Sandy soil where I live simply acts like a sand blaster, rapidly dulling the blades after mowing 3 acres twice. After mowing 5-6 times the elevators are gone.

I too live in an area that is mostly sand. I was running through a set of Cub Cadet blades every year. My 60inch deck has blades with a high lift back and the sand would hit the bottom of the lift area and erode the metal super fast. By the end of the year there would be a one inch (or more) "V" worn into in the end of the blade.
I ran across a set of blades made with something called "Marbain Steel" and if you will pardon the pun, they wear like iron!
I have been using the same set for three years now and they are worn, but are far from being worn out.
I got them on-line from "Pro Parts Place" the blades are marked as XHT (stands for Extreme Hardness Toughness).
Look, buy 'em or not, cause I got no dog in the hunt. All I know is that they have worked very well for me and cost me less than OEM junk.
I hope someone finds this useful.

Sand???:)

I go through a set of Gator G5 blades in two years as I mulch mow only with a sealed deck on my northern Florida yard. Going with the G6 Gator blades now, Those XHT blades sound interesting if you are side discharging.

I wonder if anyone has tried using liquid nitrogen to harden the blades…(?)

I recently had a question about mowers and I found a website - lawnmowerforum.com. A poster there said Marbain blades (and another brand I've forgotten) were premium blades and about the best you can buy for a commercial mowing operation.

I read about Marbain blades awhile back. They are great for your type of situation. For me hitting rocks they are too hard and brittle. I think @Mudyapster has similar sandy conditions to you. I hope he finds this because he's wearing blades out like you did. I forgot about the marbain blades. Thanks for the reminder. (y)

If you're referring to Fisher Barton's MARBAIN blades, these are what Scag uses on all their equipment. I've said it before on here a few times that they are far the toughest sharpest blades I have ever used.

For sharpening blades I use all three common tools. I get the rough spots out with a bench grinder, then I dress up the bevel angle with a flap disk on a hand-held grinder, then I finish with a flat file.

Sounds involved, but it goes pretty quickly and gets good results for me.

Looking these blades up now. I get 28 to 30 hrs out a set of blades and they are eat up and shot. I have 5 new sets on hand but going to try these from Pro Parts. Thanks for the heads up

In my experience Marbain blades are the real deal, noticeably longer wear and noticeably harder steel when you sharpen them, worth the money in my opinion.

I was fortunate to acquire a Lesco blade sharpener from my Dad, works nice.
