Toothed Timing Belt
The Dual-Force deck relies on this cogged belt to maintain the specific timing between the two blades. If the belt stretched, broke, or jumped teeth during an impact, the blades will no longer be held in their non-interfering 90-degree phase, causing them to collide at the center of the deck.

Blade Driver/Adapter
These adapters are designed with sacrificial lugs that act as a mechanical fuse. If the blade hits a stationary object, these lugs shear off to protect the engine and spindle, but this allows the blade to rotate freely out of time with the secondary blade, resulting in constant clashing.

Blade Spindle Assembly
If the internal bearings or the spindle shaft itself have been compromised or bent, the blade may wobble or sit at an incorrect angle. This geometric deviation can cause the blade tip to intersect with the adjacent blade's plane of rotation even if the timing belt is still intact.
