Left to rot for 10 Years, will it start? 1980's Holder A65 Tractor!

Short introduction to my latest and greatest project, a 1980's Holder A65 atriculated tractor. I've bought it from volunteer workers who had left the tractor unattended for 10+ years. In this video, I replace the battery, top off the oil, fill the radiator and try to start this beauty. Who can tell me what causes the leaking of the radiator?
