We got it working and it pulls us up the hill!! We have a Riding lawnmower powering it. If anyone wants to try building one I really encourage you to. I'm surprised at how well it worked!! I'm pretty pumped about it! I'll make a better video later (higher quality) where I walk around and show each part and how it works, in case someone else wants to copy it. Total cost was just under $200 I believe. $100 for the riding lawnmower!
