The gate hinge has been modified over the years to make it durable and wear resistant. It is designed as a “clevis” rather than the old plate-over-a-plate design. The old design was much like the competition that had a plate that folded over another plate. The trouble with this design is that it required constant cleaning to allow the plate to completely close over the other. Otherwise the blades would gap from each other. The old design would also stress the gate pin and it would wear, get lose, or fracture. The new gate design eliminates all of these issues.
