Testing the Brush Rake, Grading Bucket and Quick Attach System on a China Mini Excavator Digger

After switching the Bucket for the Grapple I put the China mini to the test clearing some thick brush and roots at campsite #20. I also use the smooth edge clean out bucket. The Machine in the video is a Rippa R320 with the Rippa brush grapple, and quick attach. The black smooth lip bucket is the Rippa and the Yellow smooth lip bucket is the China Coal. The buckets seem to be interchangeable between machines. During this project I also question how hot should these machines run? 210F? seems ok but when your sitting on it, it's hard not to notice the heat. What is other people's experience with the heat on mini diggers? I added a fan to the gas China Digger ZM 10 should I add on the the Rippa R320? Where would you put it, I'm think by radiators? Thoughts?
