The gun weighs 45 lbs..
The box rack complete with full belt, battery and air tanks weighs in at 60 lbs.
That's 105 lbs up top.
I haven't weighed the frame or the wheels yet.
The wheels are pretty heavy.
There is an idea to have three points to carry it over rough terrain, in that case I may use skid plates instead of the wheels. That should reduce the overall weight and help keep control of it on steep ground.
I plan on having the option for wheels or skids to be determined by the terrain of the field.
A field like Blanding (paved streets = wheels).
