This portable greenhouse gives me a head start on spring and extra protection for plants in the fall. The light rod and flat iron hoop framework forms a track for raising and lowering the plastic front and back. Curtains can be set at any height by adding light chain.
Ends can be open or closed.
The entire unit can be easily disassembled or moved intact with a front loader. Hooking to a swivel hitch tongue by yourself is made a lot less difficult with this tool. I keep it in my tractor toolbox. I welded a same size nut to one of the bolts to help hold the hitch higher. You can use any size bolt that fits the holes.
