Load and Speed
With just a few parts, you can convert your tractor into a transport
vehicle. A base plate serves as the large cargo bed.
1. Insert four anchor pins (26) into each of the long side frames on both
sides of the vehicle. Attach the pins to the upper and lower portions of
the frames as shown in the picture.
2. Now hang a short frame (3) on the four anchor pins on one side of
the vehicle. The lower end of the short frame should align flush with
the lower section of the long frame.
Conversion to a
Transport Vehicle
As you know from sports, force can be applied in
many different ways — to lift weights, for example, or
to run fast. It’s the same with your solar engine. The
two most important jobs that a vehicle engine does
are to transport objects and to create speed.
In order to transport objects, your solar vehicle needs
a cargo bed. For that, we will first have to rebuild your
tractor a little.

You will need: solar tractor, 1 x base plate (1), 2 x
short frame (3), 8 x anchor pins (26), bright sunlight,
smooth and even surface
Instructions
Rebuild your tractor into a transport vehicle by add-
ing on a large cargo bed as shown in the pictures on
these two pages. Run your transport vehicle in bright
sunshine on a smooth, even surface — for example,
the back side of a large pad of drawing paper. What
happens?
