In Ma Lin's Blue Planet hometown, hand-held tractors were once an affordable machinery used for farming, transporting, operating cranes, water pumping, and more.
They were very convenient and could power various types of machinery.
Ma Lin really hoped that hand-held tractors could also become popular here.
But consider this issue.
In the Gem World, the small people were only forty centimeters tall, and they couldn't operate the type of hand-held tractors from the Blue Planet.
However, if you want to plant wheat and corn, the soil must be deeply plowed, so the tillers need to be large and powerful.
Hand-held tractors need both hands on their handles and feet turning the single wheel below to control the direction.
The little people have neither long enough hands nor feet.
So, they couldn't adopt such a convenient design.
