To build it you would need
2 bars of any strong metal (wrought and cast iron, steel, bronze)
40 boards
25 block
5 rope (for pulleys, and attaching to cow)
3 bone glue
2 hardened leather
3 hide strap (reigns to control ox)
6 linen or silk cloth (bag in which to hold seeds/ vegetabes)
you would need basic mechanics and ox carting before being able to build it. It would function like a plow but be between 2 to three tiles wide, once it passes over a tile, like a plow it harvests the crops as if they had been harvested normally (maybe with a slight lp loss over conventional farming) meaning that the plant fibers/straw falls to the ground and the seeds are but into the harvesters inventory. The harvester could be used in conjunction with a silo or other stock pile viewtopic.php?f=5&t=6073&start=0&hilit=silo. This would allow for crops to be harvested faster and with less stamina drain. I'm probably off on the amount of materials that is reasonable, so if you think you have a better number or better material choices please post 'em.
I hope this makes sense, do you think it's a good idea?
