Latest Model Zero-Max VRT™ Variable Ratio Transmission Dispenses Seed And Fertilizer With Precise Metering Rates In Agriculture Equipment

Plymouth, Minnesota: Precise metering rates of seed and fertilizer in agricultural equipment is ensured with the latest model Zero-Max VRT™ Variable Ratio Transmissions. Infinitely adjustable to lock in the rate, the VRT transmission ensures correct dispensing of seed and fertilizer.

Zero-Max’s ground-driven system is the vital operating link between advanced control systems such as GPS (global position systems) and the mechanical dispensing mechanisms used in precision seeding machinery.

In the agricultural equipment pictured, Zero-Max VRT Infinitely Variable Ratio Transmissions are used as the mechanical interface of the electronic controls and the seed metering mechanism. With all internal parts machined to strict and consistent tolerances, these transmissions ensure accurate seed dispensing for exact spacing over the entire cultivated field. Seed placement accuracy is maintained even when equipment ground speed varies. It provides the mechanical consistency and transmission accuracy enabling the equipment’s electronic controls to operate precisely in varying seeding conditions.

Ruggedly designed to operate in the harshest environments, the VRT’s aluminum housing locks in mechanical drive components. The drives are pre-lubricated during assembly and completely enclosed in the heavy-duty housing. This maintenance free design ensures that internal parts are lubricated and free of contamination from outside debris.

Zero-Max VRT Transmissions are available in both standard models and custom designs for specific original equipment manufacturer specifications.

“With today’s precision farm management relying on the latest technology, Zero-Max VRT Infinitely Variable Ratio Transmissions help make precision farming more efficient and profitable,” reports Zero-Max design engineers. “Field proven for over 10 years, they are designed to integrate effectively with innovative agricultural equipment utilizing geospatial tools to maximize returns on inputs while preserving resources.”
