Thinking about buying a 55 gal 3 point sprayer with pto 6 roller pump for my JD 3720 cab tractor. Dealer has Ag south and Demco sprayers? Ag for $850 and $1300. Any pros or cons of each? Either one more cab friendlier then the other? He has none in stock so which ever one I pick he has to order. Probably going to go with the Ag South as long as there are not bad reviews. Thanks.
