I just got the new sprayer I had been talking about in the KIOTI thread. It is a 300 gallon tank and trailer with a 36" boomless nozzle. I have hooked it to the DK40 Kioti, filled it with water and will try to calibrate it tomorrow. I had been spraying the small paddocks around the farm with a 60 gallon tow behind using the RTV 900. What a difference this extra capacity will make. It is my policy to check most fittings etc behind everyone,including myself and as I was pushing and pulling on the coupler, it just slipped right off the shaft and key of the pump. The set screws were lose. I tightened them and put a dab of loctite on , I also need to tighten up a fitting that has a drip but then I will be ready to spray and get some seat time . Bordercollie
