Zero-Max Announces Introduction of VRT™ Variable Ratio Transmission for Agricultural Seeding and Fertilizing Applications
Mar 19, 2021Plymouth, Minnesota: Zero-Max new VRT™ Variable Ratio Transmissions feature an efficient and cost-effective design that ensures accurate and consistent application rates for agricultural seeding and fertilizing equipment.
The Zero-Max VRT is designed to meet the performance requirements for today’s agricultural equipment. The VRT can provide a critical link between the control system and the mechanical seed and fertilizer distribution mechanism. This seeding system, often ground-driven from the wheels of the implement, maintains seed and fertilizer placement accuracy even when the ground speed of the equipment changes.
Outstanding Zero-Max VRT features:
- Infinitely adjustable to obtain the exact desired ratio.
- Ratio can be adjusted when idle or when running.
- Easily, quickly and precisely make speed adjustments.
- Variable ratio or fixed ratio operation.
- Speed and torque capabilities are expandable by use of chain and sprocket ratios at the VRT shafts.
Encased in a secure heavy-duty housing, the VRT resists dirt and debris, is pre-lubricated and withstands the harshest environments and climates. It is designed for reliable operation with minimal or no maintenance.
Available in two sizes, each offering 0-300 rpm input speed and a 0 to 0.25:1 ratio range of output to input speed. The VRT-150 is rated for 150 in-lbs torque value with the VRT-300 rated for 300 in-lbs. Both sizes are available with input and output shafts on the same side or opposite sides of the housing, with output shaft rotation in clockwise or counter-clockwise direction and with a variety of control options. Special designs are available.
