The problem is that Lloyd said his "Bush Hog" was a 60' RFM, but had reverse cutting blades with 3/4" holes. On every Bush Hog model of 60" mower listed on their website, they use part number 82324 which is a CW cut blade, 21" long, and with a 1/2" arbor. Amazon sells replacement blades for around $17-$22 each. The only thing I can think is that Lloyd doesn't really have a Bush Hog brand mower, but is using a generic term for some other brand. That's the point RickB was making. Any description of the mower needs to include the exact model number and brand for us to give accurate help. As far as I can find out, none of Bush Hog's current models are reverse cutting or 3/4" arbor. Perhaps Lloyd meant "rear discharge" instead of reverse cut. It would seem that unless he can post a follow-up with more info, his request is "dead-in-the-water."
