It attaches to the hole in the drawbar and it doesn't work well at all. It lasted a year or so and caused enough problems that I did away with it. I just bolted it to the rear basket and it is rock solid now. If you don't have some kind of a rear basket, you might want to look at another model.

There's not that much difference in these things. They are just a tank, a pump, and the hoses and nozzles and cutoffs. All of it can be easily replaced by something you can buy of another brand.
