Seed Belts & Bases
Any machine must be configured properly to achieve optimum performance. This is especially true of Stanhay planters, which must have the
correct combination of belts, bases, and repeller tires to plant at its greatest accuracy.
Our seed testing system closely approximates field conditions, so we are able to "plant" the actual seed that will be used in the field. This lets us
view the "planted" results before recommending the proper belts and bases for your specific seed.
Choosing the correct spring-base is as important as using the proper belt. If one of the standard bases doesn't meet your needs, ask about our
custom bases.
