VALMAR Operation
Page 11
4 - Operation
Your Valmar applicator is designed to efficiently broadcast seeds and granular chemicals.
As noted in the diagram below, the system operates by using a hydraulically (optional gas engine)
powered
fan to blow product through an air delivery system. A grooved metering roller accurately
meters product from the hopper into the venturis . Air passing through the manifold and venturis draws
the product into an airstream and sends it down a distribution hose where it can be spread by a
deflector . Product application rate is controlled by a sixty speed gearbox driven by a metering wheel in
contact with the ground.
