I'm looking at mounting a Walinga Grain Vac on my truck. This isn't a real issue in itself as Walinga makes truck mount kits that will bolt on. However, as usual, I want more power and speed than what they claim the unit is capable of. The blower they install(a 614) is capable of moving 5000 bushels per hour when run by a 150hp farm tractor. However running it via PTO off a 530hp Cummins will only get 2000 bu/hr. They claim rpm and torque are the limiting factors. Is there a way around this? I thought perhaps running 2 blowers but that would obvoiusly have torque implications. Do they make heavier spec PTO units? Are there ways of direct driving off the motor? Could I use a large hydraulic pump and orbit motor set up? Are my questions getting stupider as I go? I'll stop now!
