Align Main Drive Gear (2) (78T)

Extremely delicate. The teeth don't strip but the keyed center hole strips. The plastic key shears off with only a minor blade strike. Brush the grass a little and your main gear is gone. Goes crooked on the shaft and spins on the main shaft. No longer solid. You will notice the motor surge when the key is stripped out and the gear will wobble. Needs to be a whole lot beefier in my opinion. Just ordered eight of them. Easy to change but a pain in the butt for every minor blade strike. Would be better if the key was longer or made part of the metal insert instead of the plastic part.
