This OEM keyed blade adapter connects your lawn mower blade to the spindle, enabling it to rotate and cut the grass. It has a length of 1.19 inches, an inside diameter of 7/8 inches, and a bow tie center pattern. If you notice unusual grinding or rattling sounds coming from your mower, or if you feel excessive vibration in the handle or cutting deck, it could indicate a broken blade adapter. Similarly, if the blade is not engaging properly or wobbling, it may be a sign that the adapter is worn out and needs replacement. To replace the adapter, start by tilting your machine backward to access the blade. Use a socket or wrench to unscrew the bolt that secures the blade. Then remove the support, blade, and adapter. When installing the new adapter, make sure to align the key on the adapter with the keyway on the shaft. Before operating your lawn mower, ensure that all of the components within the blade assembly are installed properly and securely in place. Please note that this replacement part does not include any accompanying hardware.

I need the blade adapter that fits on a Ryobi 42" electric zeroturn mower. this adapter has to raised places that fit on the blade. one side is round and theother is half round. I also need the beveled washer that is used to put pressure on the blade when the nut is tightened to prevent the blade from becoming loose. I did not have a repair diagram or parts list for these parts. I ordered a flange nut and it does not fit the bolt coming out of the motor.
Need: flange nut, blade adapter that doesn't look like a star (it is round) and the correct curved washer (not flat), that goes between the blade and the nut.
Thank you
For model number ry48ztr75
