Alright Z-spray owners, I need you to get this one right. Recently bought a PG Ultra (now have 25 hours on it). My first problems came at 12 hours when the butterfly stuck in "choke" and machine flooded and wouldn't restart for 15 minutes (happened several times before I gave up and used my skid sprayer to finish). The second property that I was left stranded I talked to Tom Rich and he gave me a quick demo on a z-spray jr. (no actual production since he was delivering that unit). He seemed to be a real standup guy and the machine looked and felt WAY more solid than the PG. I actually had him build me one with several upgrades (200 lb hopper, 50 ft hose reel, larger rear tires), and it is ready to be picked up ( trying to find time to do it in a couple days). Once I got the PG running, I have been using it and have gotten pretty used to it, however there are SEVERAL limitations to it in comparisons to the Z-spray. The smaller hopper size, the WAY underpowered engine, 34k versus 60 k per spray tank, and the drive system in general. My question, with all the above observations, will I regret trading the PG for the Z-spray? Once I trade in the first PG, I lose that option if deciding to go back to it, and I really don't want to be in the position again of deciding I don't like the Z-spray after using it for awhile ( not to mention having to return yet ANOTHER machine and generally having all the manufacturers p*#*#*# off.) With all the posts on the reliabilty problems of the PG, it really sounded an alarm when I had my first problem so early. I have no doubt the spray system on the Z-spray is better, but I have no experience with SPYKER and since I only do one blanket weed app and the rest are granular fert with spot sprays it is imperative that the spreader be top notch. Have any of you had problems with the Z-spray spread system? How do you handle trim passes since there is no 3rd hole shutoff for when the deflector is down to cut the rate back. How does the unit handle hills with a full hopper and spray tanks? ( I had the PG on some scary hills and it did alright, but the fert hopper was empty). Does it slow way down going up even little hills like the PG does? How about runaway going down hills (shouldn't since its a hydro.)? How easy is it to open/ close hopper while moving and turning? ANY serious down time with the unit (a BIGGIE)? Like I said, input is really appreciated since I will be making the switch this week and don't want to put myself OR Mr. Rich in another uncomfortable position since he has been pretty helpful. BTW properties I treat run from 2000 sq ft to 17 acres, with most in the 8-20K range and several 1+ acres.
