Sounds to me you might just be qualified to plant grass. But the biggest problem I had with your post was the down right damming suggestions about cheap plastic tanks wont work. I feel that most of these comments are just not appropriate nor are they totally accurate. One of the reasons I got into hydro seeding was because of the quality of work of a local hydroseeder that did a lawn for my Mother. He showed up with a plastic machine sprayed the ground green collected his money told us to keep it watered and left. I was helping her remodel the house and was there every day and we watered it just like he said. 3 weeks later, very little grass. He never came back and I ended up broadcasting seed and covering with straw. This fellow has since purchased a Finn to hydroseed with so you would think his performance would have improved but just because he got a new machine didnt mean he knew diddley. This person is a member on this site so I am not going to call names, but when he gets on here talking about his quality work I have to bite wood to keep from screaming. The machine hasnt made a bit of difference in his seeding jobs. My first Machine was a hurricane from Ketchum Manufactoring. I bought into all of there claims about it being able to mix 50 lbs of 70/30 real mulch and not just jet junk. It wouldnt even mix half that. The Ketchums now have 18 counts of fraud and other matters to defend against from the Oklahoma Attorney Generals office. I have modified the machine now so that it will mix wood mulches, not 50# per 100 gal of water but thick enough to seed the way I try to seed. I also had plenty of problems getting seed to grow but if I have a problem I do go back. This site has helped me learn a lot about what my problems have been but so has Turbo Turf's help site. I dont have the call backs now that I had in the past. I'm not 100 percent yet but I am working on it. I also have attended several classes reguarding turf and turf management and have plans to attend several more. I spend a lot of time researching on the web different seed types, fertilizers and anything else I feel I need to know to help me with my hydroseeding business. I have tried the heavy mulch rates that you are suggesting to use and I have been less than impressed with the results. I purchased my bowie machine just so I could spray these heavy mulch rates but I found that was another waste of money, Not the machine but the ideal that I needed the heavy mulch. I now try to use 1500# per acre and the results are more inline with what I expected them to be. There are areas that I use more mulch on just to keep them from washing. I get the same results whether I am using the bowie or the jet machine, The jet machine cost me half of what the used bowie did. The bowie will pump more thru long hose and spray farther from the tower gun than the jet machine will but, I am always having to grab a grease gun and cant seem to keep it frm leaking around the packing glands for the agitators. The jet machine justs get washed out after each job. I know the bowie is a 69 model but it only had 60 hrs on it when I bought it. I already see the maintance downside to owning it, but I dont regret buying it. When I purchase a new machine it will be a mechanicly agitated machine. But just because i would choose a mechanical machine doesnt mean that quality cant be had with a jet machine. I got the jet machine in march last year, it paid for itself in 6 weeks, by oct. it had paid for the bowie which I purchased in dec. I use the jet machine more than the bowie so the bowie still hasnt paid for itself altho I am using it more now than I did earlier but, its not because of the better results but, because of its larger capacity. I have the same turn time whether I use the small machine or the large one, just no way around the water issue. You seem to have a great knowledge of hydro seeding, whynot spend your time here sharing that knowledge instead of using it to blast turbo turf or anyother jet machine manufacturer. I do agree that there are a lot of manufacturers out there whose business ethics could use some improvement, But Ray at Turbo Turf has been more than straight up with me and at least on his web site he will let you discuss anytype of hydroseeding machine and/or manufacturer. The main goal there seems to be to help the hydroseeder learn how to do it right reguardless of what type machine you use. You are invited to join in, everybody could benefit from the expertese that you seem to have. Seems to me that people sharing information will help this industry more than requireing some sort of certification. Everybodys required to have a driver license to drive but that dont mean that everybody that has one should be allowed to drive.
