The drive pulley adapter compatible with MTD, Replacement for 687-02528. The blade adapter just the blade adapter -- no bolt or blade washer. It’s used to link the motor pulley, blade, and the belt to allow the drive shaft to rotate the blade.
Easy installation:Clean the shaft before install--remove the blade---- remove the old pulley---put the new pulley on, and there is lots of YouTube videos to tell how to do it.
