I just purchased a Mini Z 52 a month ago. Recently I noticed there was fluid on the ground. Upon further investigation, I found hydraulic is leaking from the hydraulic reservoir (looked to be a small pin hole in the welding around the drain plug). I am a bit disappointed and thinking something like this should have been inditified. It makes me wonder what other parts would have the defects. My dealer said they don't have the tank in stock and they will have to order it. Looks like I will be out 7 to 10 business days. So I am out for approx 2 weeks.
