First day and having issues. The first thing that aggravates me is before this machine has even ran the dealer came out and tore into the cooling system... That shouldn't happen on a brand new machine. Now we get to harvesting green peas and we can't even load the engine because the chopper starts making the worse noise I have ever heard! We have inspected every thing about the chopper and cannot find the cause. We also have a s-77 that has the same chopper issue. I can only run 50%engine load or the chopper sounds like it's gonna fly out! The reason I reference the s-77 is because it still has all discharge paddles and slow chopper. The s 78 has speed up kit and removed discharge paddles and behaves the same. Also the cage build up on s-78 is terrible! Also the hydro stat is the weakest I have ever ran and piss poor brakes.
