Zero-Max Adjustable Speed Drives Seed Lawns And Distribute Fertilizer Their Accurate And Repeatable Drive Settings Ensure Quality Results

Zero-Max Adjustable Speed Drive mounted on grass seed dispenser. Seeding rate is easily adjusted with a hand lever.

Plymouth, Minnesota: When designers looked for an easy way to adjust application rates for seeding and fertilizer distribution, Zero-Max answered with its line of Adjustable Speed Drives.

For applications that include precise golf course green seeding or large farm acreage fertilizer distribution, there's a Zero-Max to handle the need. They are available in standard and custom models and sizes.

Designed to provide accurate and repeatable speed settings, these Zero-Max Adjustable 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 drive line. 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.

Accepting input speeds from 0 to 2000 rpm, output speed changes using these Adjustable Speed Drives can be made quickly and easily, whether the machine is running or not. For example, output speed is infinitely adjustable from 0 to 400 rpm with an 1800 rpm input speed. The drives provide speed control for inputs from 1/4 to 1-1/2 HP applications with output torque ratings from 12 through 200 in-lbs.

Output speed for the drive is set quickly with the control lever adjustment. An optional screw control or Micro Dial™ feature provides a clean and accurate reference for applications that require repeatability. This allows users to more accurately set and repeat various settings to meet performance levels for different applications — for example, more or less seed, more or less fertilizer. When the Adjustable Speed Drive with the Micro Dial is used in a seeder cart application, different application rates can be made more accurately for dispensing corn, wheat, oats, etc.

Additional design features include: easily mounted in most positions, handles any input such as chain, belt and couplings, easy to install — no wiring needed, factory lubricated, compact and economical.
