This sprayer is designed to be used as a broadcast sprayer for wide, open areas. It doesn't appear to include a wand; you could add one by adding a tee to the pressure line and a shutoff valve for the boom, however. It also does not include a tank. Also, the spray heads do not appear to implement a diaphragm system to stop them from dripping when the pump is shut off.
What you're really paying for with your choice is the platform that holds the tank to the tractor. Most people on this forum would probably try to construct their own platform for the sprayer.
I know this is a horribly late response but I think there are much better options out there.
