Labor is expensive in many countries. :)

  Farmers already drive sprayers to kill weeds, so it's not like this would add labor costs. Maybe it's more expensive than chemicals, so they needed some other way to be cost-competitive.

    That was mentioned in the article. Spraying weeds happens quite quickly. This vehicle maxes at 5mph so presumably hauling it around would take a lot longer.
