A Czech Republic based tractor manufacturer that makes friggin' indestructible tractors. They may be ugly as hell but they are built like tanks. And on the occasion something does break you can literally fix it with anything and it will still run just fine. These things are basically the Toyota Hilux from Top Gear disguised as a tractor.
Hey man, your tractor's differential is broken.
PFFT! It's a Zetor, put some zip-ties and some duct tape on it and it'll be good as new.
