Just a thought... I purchased a 1000 lb. capacity wire mesh four wheel wagon at TSC and also a 30 gallon 12V Fimco spot sprayer tank with wand. Northern Tool had an ATV boom kit that had all the hardware to mate to the Fimco tank sprayer. I mounted the boom on the back of the wagon. All total I have less than $200 in the setup and get lots of use out of the four wheel wagon when harvesting the garden.
