Hello, I hope you're well. I need to design a pedal powered tractor. You can have a basic idea of the design that I'm willing to design by looking at the slides attached. What is needed now is a morphological chart showing functions of the tractor and means of completing the functions. The functions I have in mind up to now is that the tractor should 1) Cultivate 2) Seed 3) Weed 4) Resist high temperatures. Please add more functions that you see as appropriate. Maybe you could add transmit pedal power to wheels for example. Furthermore, I need 3 sketches of 3 different conceptual designs based on the morphological chart made. I need sketches to see and understand the different designs in mind. I have one design ready. I got it off the internet. This is the site that shows the design.

Therefore, 2 more designs are needed. I'm thinking of having one of the designs powered by 2 people instead of one.

 Attached is the task description of the conceptual designs.
