Clear then after construction: It actually was missing only a washer!
The structure itself is not recommended for a single person. A second man should therefore tackle definitely with. Not because of the weight, but to parts of the screw to hold.
The construction with 2 man but is absolutely no problem and also not very strenuous. The assembly instructions are easy to understand.
The trailer itself:
That part seems robust at first glance. I myself am going to the pan but och stabilize with a wooden plate something that I should not destroy the good piece. Because unfortunately the tub, not of metal but of plastic ... which is a shame.
The cart is a nice size and it fits a lot of stuff purely for transport.
The pedestrian has the front a device with which it can be attached to almost any lawn tractor easily, with no additional items.
