smarter farmers use schumacher. period. i sell both. i'd rather sell caseih or deere. puts more money in my pocket. the blades and guards wear together, meaning total replacement at some point. the sch, for short, wears differently. knife bar(not back) on wear bar(not guard). if using double sided heat-treated bars that means you can flip them three times after the first use. try doing that with any oem guard, and see where you end up. yes, it's superior; and yes expect to pay for it. great to have if you don't have a dealer close-by, too.
