Excellent product; Fits perfectly; Small engine mechanic told me that the adapter can break if you mow over a rock or curb. Just common sense to avoid them. This is OEM from Troy-Bilt but can fit other mowers including MTD of mine. I bought a universal 22 inch replacement blade from Atlas (Canadian Tire) which fits the adapter perfectly. The confusion is that there are multiple part numbers for the same part: 753-06315, 753-0588, 748-0376E, 748-0376C, 748-0376 fits MTD: 46 SP, 53 SP, 383 SP, 384 SP, 410, 508, 510, E 458, GES 45 Q, GES 46, GES 53, HBM 50, M 46, RP-21, SB 46, YM 4018 S, YM 5018 S, YM 5518 SE Replaces Old Part Numbers: 748-0376 748-0376A 748-0376B 748-0376C The curious thing is that it costs less even after exchange difference than to buy from 鶹.com and is half the price than Canadian Tire
