Crazy it took you so much filming to get 200gb of files.
But rest assured that the this video came out very well and it's easy and understandable to watch.

I grew up and still live in a very small village where tractors are basically everyday part of my life. Awesome machines and my dad always says "They are easy to fix".
The tractors around my homeplaces are really old (I'm pretty sure russian manufactured) and don't have that many moving parts as yours does :D
I still couldn't fix one myself.
