Are Orbit-Air models designed for specific implements?

No. All Orbit-Air models are equipped with a rectangular, universal tubular steel frame mounting base.

Can fertilizer be used in the Orbit-Air?

Yes. Fertilizer can be used in an Orbit-Air equipped with red or yellow metering wheels. Application rates are determined by the density of the fertilizer in pounds per cubic foot. Please note that models with an “N” designation the model number are not recommended for fertilizer applications.

Can Lock ‘N Load lids be added to the hopper?

Yes. Hopper lids can be die cut and Lock ‘N Load valves can be installed at the factory. Please note this is a special order item.

Do all 62-series Orbit-Air models have a hydraulic blower?

Yes. The blower is driven by a 3-port, 8-gpm hydraulic motor that uses the tractor’s hydraulic system to produce 8-20 oz. of air pressure depending on the recommendation for the product being applied.

How does a Zero-Max controller work?

Externally, the unit consists of a rugged, sealed cast case, an input shaft, output shaft and speed control. Speed of the output shaft is regulated precisely and easily by a screw control to hold speed at a desired setting. The general principle a Zero-Max is that it gives infinitely adjustable speeds by changing the distance that four or more one-way clutches rotate the output shaft when they move back and forth successively.

I don’t have room on the implement to mount the Orbit-Air. Are there any other options?

For smaller units – 21.9 and 30 cu. ft. hopper sizes there are pedestal mounts for the hitch. Part no. 62170 is for an 8" x 12" rectangular tube and part no. 62172 is for an 8" x 10" rectangular tube.

If my implement has a constant speed shaft do I need to purchase a ground-drive?

No. If the implement has a shaft that provides a constant rpm when traveling through the field, you can fabricate sprockets and connect a chain drive to the zero-max to provide input.

Is a case drain required?

Yes. The third port of the hydraulic motor is a case drain that must be returned to the tractor’s oil reservoir.

Is it possible to block off unused air chamber outlets if they are not needed?

Each Orbit-Air comes with a specified number of blank plates to seal off air chamber outlets. Keep in mind there are two types of blank plates: for narrow openings (“N” found in middle of model number) order p/n 62851-48. For standard air chambers order p/n 550829-4.

Is it possible to block off unused metering outlets if they are not needed?

Yes. Just simply slide the gate closed behind the metering wheel.

What are my choices for connecting a ground-drive to a 62-Series Orbit-Air.

Based on the size of the Orbit-Air hopper, Gandy offers a selection of ground-drive options.

Alfalfa, Canola, Cotton, Flax, Hybrid Pearl Millet, Milo, Oats, Sorghumum-Sudan, Soybeans, Sunwheat, Wheat, Yellow Mustard, Yellow Clover, White Rice, etc.

What if I want a larger capacity hopper, but, only have enough room for the mounting base?

Gandy offers hopper extensions that increase the height and capacity of the hopper, while maintaining the same base size. Hopper extensions are available for 21.9, 30, 80 and 120 cu. ft. hoppers.

Are there any special metering wheels for large seeds?

Yes. A white metering wheel is available for large seeds such as soybeans, field peas, etc.

What is a black metering wheel used for?

Black metering wheels are specially designed for granular chemicals and small seeds at lower rates such as alfalfa and canola.

What is the red metering wheel used for?

The red metering wheel is used to apply fertilizer and small grains such as oats, wheat, rice, barley, etc.

What is the yellow metering wheel used for?

The yellow metering wheel is specially designed for high-volume applications of fertilizer and seeds such as sunflower. Delivers approximately 1.5 times more fertilizer than red metering wheels.

What are half-rate metering wheel used for?

Half-rate metering wheels do exactly what their name implies. For example, if a full rate metering wheel outputs 10 lbs., of material per acre, a half-rate metering wheel would output 5 lbs. of material per acre. Typically, half rate metering wheels are used in applications where the rate is below 5 lbs. per acre.

While in the cab, how do I know the shaft on the metering wheels are turning and the blower is functioning?

Gandy provides a console for the cab with indicator lights telling you the metering wheel shaft is turning and the blower is supplying the proper air flow.
