I use my C.A. as a base for my 15 gal sprayer. Rather than buy the tow behind style with its own frame and wheels, I got the type designed to strap onto the back of an ATV. I place a short 2" x 12" board across the C.A., put the tank on that, and bungee it down. Spray pump is elec, powered from the battery. I got the sprayer on sale at Northern for $89 which saved a good deal of $ over the wheeled kind. This also saves space as the tank alone is easily lifted to a storage spot atop a cabinet or up in the garage trusses.
Most of my implements have dollies, but for the C.A. I bolted four 2" casters to the bottom. It rolls around easily. I store it with the forks rolled beneath the rough cutter, which is sitting on its own dolly.
