Elimination of Complex Connections and Maintenance Points

What happens here

A significant benefit of the Arctic snow plow's design is the complete elimination of several common components that typically require frequent maintenance or can be sources of failure. Specifically, the design effectively does away with 'all hoses, all grease circs, all electrical connections, and all hydraulic hookups.' This simplification drastically reduces the complexity of the plow system, making it more robust and less prone to issues associated with these traditional components.

Goal: Identify which common plow components are eliminated by the design.
