Inspect Snowplow Mechanical Components

What happens here

The narrator then provides a closer look at the snowplow's hydraulic mechanism attached to the truck's front. He points out that the crucial 'arm that pushes up and pulls the chain up' to lift the moldboard is missing. This absence is identified as the main reason for the plow's inoperability. The video clearly shows the hydraulic hoses and other components in place, but the key lifting arm is visibly absent from the assembly.

Goal: Identify the primary mechanical fault of the snowplow.
