I have a 3630 spray coupe with a 4 cylinder diesel and a trailer. the sprayer has couple hydro leaks (cylinders) but everything else seems to work as it should. Has a tee jet monitor only 1 year old and is 74 feet I also have a new pressure gauge I have not put in yet. Sprayer has 3000 hrs on it. The trailer has 1 year old predator pump on it and could put the sprayer on it if put smaller or belly tank on it. I do have a hitch to pull the sprayer as well. Every thing seems to work as it should just looking at getting into something else. Thanks.
