Yes, I too have had issues with the Blade Adapter... The star Pins shear off too easily. I have changed at least 3 and this last time, my local dealer says I have to tighten the bolt to at least 100 ft lbs... I say the product has faulty engineering and should have a better adapter to handle the torque of a blade. I would not recommend this product to anyone.
