I just got a new 15 gallon sprayer from TSC on sale for $69.99. I'm wanting to put it on a carry all to hook up to the 3pt hitch on my tractor, but I'm gonna run if off of a battery and I'm guessing it should be a marine style battery but not sure what type I need or anything. I know I could run it off my tractor but I would rather use the battery setup I can use it on other tractors as well. Suggestions are welcome on a setup and battery size.
