[dragonball]why does goku use a tractor to plow when he could do it by hand at near light-speed?

- It makes  Chi-Chi happy to do it this way.  She can brag to her friends that her husband is an honest hard-working farmer and not a freakshow that punches the earth into being plowed.

- Plowing by hand with his martial arts skill probably does unintended damage to the ground that makes it harder to actually farm.

- Plowing the ground by hand probably isn't as fun as fighting or conventional training, so Goku isn't too eager to go and do it that way.
