OpenRC Tractor - Field Disc

This makes for a decent scale model of the typical field disc as I remember as a kid.

I split the 'Disc_Gang-Whole' in two for those who are working with a smaller bed surface. They are labeled 'Disc_Gang-Front' & 'Disc_Gang-Back' respectively as optional choices.

Everything was built using M3 hardware nuts & bolts in various sizes. I used a 3mm x 120mm length of all thread bar found on amazon. The disc's were 1/8 x 1" fender washers. At the time I ordered parts I could not find any M3 washers that large.

Everything else is simply print the parts and nut & bolt things together.

UPDATE: 9/22/22

I did include an optional lift mechanism that works finally and a retro fit box to mount a MG90 servo. The open space left over forms a clever little tool box. On the rear gang includes a rock box as another cosmetic option. I used a paper clip and heat shrink to form a simple hose holder.
