I am in the process of mounting a sprayer on my JD 777. I have a F**co 25 gallon tank on the front, $179. It is a spot sprayer, but it has thesame manifold as the trailer mounted one. So, I bought a breakaway 10' boom with seven nozzles. New price was $120 including shipping from Ebay for the boom. Now I am working on the mounting plate for the tank. It mounts over the front beam and on the castor arms. I also am going to make a receiver type hitch that mounts on the pully guards under the 777. Then I can make a hitch that goes in it to mount the boom. Every thing will be quick on and off. I can remove the tank with two knobs and the boom with a hitch pin. Also, I will turn the sprayer on and off with a foot switch that doubles as a light switch whent the sprayer is not in use. Sorry if this is boring, I had to tell someone! I will post pics soon!
