I use them on my B8200 with an RC60-92H deck. I did not see a direct crossover from Oregon to my Kubota deck but by using the Kubota dimensions the crossover that works correctly is the G5 Oregon Part # 596-749 replacing Exmark Part #'s 103-6383, 103-6393, 103-6398 & 103-6403 for Exmark Lazer HP, CT, Phazer, Quest, SP and Pioneer, Serial No. 600,000 and below; Lazer Z AS, ASX, XP, XS, E, S, X, D, Front Runner, Turf Ranger and Vantage, Serial No. 540,000 and higher. I never used any additional spacers just the original hardware. They cut beautifully smooth with no issues. These blades have a longer sharpened section that I thought may be a benefit but no, only the normal amount of blade is what cuts but they stay sharp longer. I've used two sets in four years mowing 5 acres twice a month. Three blades are < $50 delivered. If anyone knows of anything better please tell me.
