Zero-Max Custom Variable Speed Drives are used as a prime mover connected to a motor, or as a secondary drive connected to a shaft in the machine’s driveline. When used as a prime mover, the drive acts as a variable speed device. When used as a secondary drive, it becomes a variable ratio device. The drive permits slow or fast, small or large speed changes.

The variable speed feature allows for more accurate settings for the map-based feeding and seeding process. For example, the Zero-Max drives can be designed to accommodate varying terrain and soil conditions where real-time changes in fertilizer output are required. (Example: vary fertilizer application from 15 pounds per acre to 40 pounds per acre or any prescribed rate). For seeding, the drives are flexible, reliable and precise to help accommodate the narrow time-window for best seeding and for different application rates needed for seeding corn, wheat, oats and other crops.

Zero-Max Custom Variable Speed Drives are available with many design options. These include designs that handle different power inputs using chain, belt and couplings. Also available are compact and lightweight drive designs and special drive designs that mount easily in most positions.
