I am looking at purchasing a skid mount sprayer and was wondering what you guys use, suggest, and what to watch for? I already know I want the Honda engine and either a 200 or 300 gallon tank. I will use it for weed control and fertilizing, I guess that makes a difference in pump choices. Also, should I get one capable of agitating the mix. I just want to make sure I get every option I will need so I don't have to get a different one a year down the road because I missed something. Any opinions are appreciated. Thank you.
