Re: Air Seeder vs Air Drill
Guys, in my experience in Australia most farmers stepped up from combines to 'air seeders' which were a dual purpose machine. That is it can be used as a cultivator/chisel plow and then changed to an air seeder by adding the air cart. This was/is considered a cost effective way of covering all the bases with one machine. Products like the Flexicoil ST820 and Morris Concept 2000 were the best at doing this by providing ground following contour-ability with flexing frames and floating hitches whilst also providing the options (harrows and/or packers - sweeps or knife openers) and strength to cultivate/chisel plow. Trash flow was OK on these types of machines (naturally depends on spacing).As time has progressed and farming methods/requirements change due to things like wanting increased efficiencies, direct drilling has pushed the need of the air drill, that is a dedicated seeding machine - not suitable for cultivation/chisel plow work, just for seeding with dedicated packer wheels. Once again companies like Flexicoil, Morris, Bourgault all have variations of air drills with only the Flexicoil & Morris having flexable frames. Trash flow was still only OK. In the last few years, the big players (Morris Contour Drill, Bourgault 3310 & I believe Flexi have a version on trial) have gone down the Seedhawk path of individual openers, even though some of the Australian manufacturers had versions before Seedhawk. They offer individual opener accuracy that far out perform the traditional air drills with less setup and lower draft requirements. Trash flow from my experience has been very good (used a Morris Contour Drill). Because these are relatively new, there aren't a lot of used/demo machines about so if you don't want to spend much, you will have to find a satisfactory compromise.
