Looking to upgrade my PG Ultra to a newer machine that will allow me more options in what products I can apply. It appears that those options have been addressed in the Z-Spray machines and the new Turfco T-3000. So if anyone is looking to get out of the business or sell their Z-Spray to get a different version I am interested. FYI, I have been happy with the PG Ultra and it has been reliable for me day in and out but unfortunately it has shortcomings that still have not been addressed with the 2009 version. I still want to be able to spray larger volumes for some insecticides, and fungicides and want to be able to apply wettable powders when needed. PG still will not allow me to do this. I will be selling the PG Ultra if anyone is looking for a reliable backup or to expand their business.
