Nevada, Iowa | What model? I am only familiar with a 1760 12 row rigid frame so probably won't be much help. Was your initial low row furthest away from the fan and did they follow in succession? Like 12 first then 11,10 so on? If so, I would suspect some kind of blockage in the pvc vac tube. Also, what does the vacuum gauge tell you, how many inches are you able to maintain? Not much help, sorry. | |
