I have two Summit Plot Mule discs. BTW, one is brand new in the box, with all the bells and whistles.:wink:
I have tried a few, and the Plot Mule works really good. It will tilt side to side on fairly steep side hills, but nothing you can`t live with.
The spreader has a cigarette lighter plug to plug right into your quad, or you can direct wire it into a handlebar mounted rocker switch.
Both of the units I have come with a 15 gallon spreader and a variable remote control. They also come with a cultipacker, and the optional electric accuator to raise and lower the wheels instead of the rachet binder, which works fine, but is a pain in the butt.
For a sprayer, I picked up a Fimco 25 gallon boomles sprayer at Tractor Supply Company. This thing works fantastic! Fully adjustable, and can spray up to a 30' swat with a single pass.
IMO, the only ATV disc that is noticably better than the plot mule is a unit made by a dentist in Texas. Check out the "ThunderDisc". It is an awesome unit, and you would need a quad like you have to pull it. I really wanted one of these, but they run $1950.00 plus shipping just for the disc alone. Well worth it, but more than I wanted to spend at the time.
The plot mule from Summit has worked really well for me.
If you decide you might be interested in a deluxe Plot Mule setup.....shoot me a PM. I really do have a brand new in the crate deluxe model, and I will be making 3 trips to the midwest in the near future. October 3rd, October 23rd, and again on November 27th.:wink:
