The Christianson Model 20 SeedVac moves bulk seed into a planter or drill through a flexible delivery hose and cyclone. The gas-powered pneumatic system can draw from gravity wagons, trucks, bulk boxes and loose piles without tractor PTO or hydraulic power.
The included delivery hose lets the operator fill multiple openings from the seed source, while the cyclone separates conveying air at discharge. An air-pump silencer is part of the package.
