An Asian man walks a three-wheeled pedal card fully of white bags.
An Asian man transports a group of bags.
"Walks a three-wheeled pedal card" is a method one transports bags.
'walks a' can be used as 'transports' or 'escorts' depending on what's being 'walked'. in this case its an object so it becomes "transports" 'pedal card fully' seems to be a misspelling of 'pedal cart full' and inferring from that a "pedal cart full of white bags" can mean a large "group of bags"
Transports is the same as walks.
