Picked up this used 200 gallon Lesco sprayer for $1600.It has the Hypro D403 pump, 5.5hp Kawasaki and a electric Haney reel with hose. I'm keeping my fingers crossed that the reels motor works properly but I didn't get to see it work. The engine started right up and sounded good but the pressure gauge wouldn't show anything. There is a hole in the tip of the gun so the antifreeze just kind of flowed out like a garden hose. Could this be why the gauge wouldn't show any pressure? The guy I bought it from said the gauge hadn't worked since he owned it. (Seems a bit odd but he bought it used also.) he only sprayed a post emergent with it and said he never adjusted the pressure. I plan on changing out all the hoses, redoing the electrical wiring for the hose reel, buying a new pressure gauge, changing the oils, filters and tuning the pump to get it ready for this upcoming season. I also plan on rerouting the bypass line into the tank instead of having it run back into the intake line. This is my first time working on a skid sprayer so any additional insight is much appreciated. Anyone with experience with this particular skid I would love to here from you. What do you like, don't like? What else should I replace or do to prepare for this season? As of right now I just plan on using this for post emergent.
