Spray System: The Z-Spray is equipped with everything you will need to apply the correct amount of chemical. The Z-Spray is equipped with a GPS speedometer to determine ground speed, the tip size is 1/3 per gallon and we know the spray width. The standard spray system on our Z-Sprays come with Hypro lavender tips. These tips are designed to spray 1/3 gallon per one thousand square feet. This is achieved by spraying at 40 PSI at a speed of 5 m.ph. These tips are capable of spraying at different volumes. This can be achieved by changing the ground speed of the machine and/or changing the pressure. Alternative tips can also be purchased for the Z-Spray. The Z-Spray can accommodate ¼ gallon up to 1 gallon tips. Please refer to the Spray Tip chart on our website.

 

Mixing of chemicals should be in accordance to manufacturers labels. Remember that the Z-Spray is designed for low volume spraying so the mix will be more concentrated.


Remember your machine is factory set to put down 1/3 gallon of liquid per 1000 sq. ft. For instance, some products call for 1.1 to 1.5 oz. per 1000 sq. ft. We would recommend using 1.3 (median value of 1.1-1.5). Since you are using a 1/3 gallon tip, you need to multiple by 3, then multiple that amount by the number of gallons you need to put in your tank.

 

1.3 (median value of 1.1-1.5) x 3 (1/3 gallon tip) x gallons needed. If you were filling an 18 gallon tank your equation would look like this:

1.3 x 3 x 18= 70.2 ounces in 18 gallons of water.

 

 

Granular System: The granular system on the Z-Spray comes in 2 sizes: a 220 lb hopper on the Z-Max and Intermediate Models and a 120lb hopper on the Junior, Junior36, and the Mini-Max models. Each hopper system is manufactured by Spyker.
The hydraulic spreader motor with the Spreader Motor Control has the ability to vary spread widths from 4 to 25 feet. This depends on volume/density, particle size and rate of travel, and weather conditions. The pattern can be increased/decreased while spreading depending on need. This allows you to spread and spray at the same time. A typical pattern is to overlap the fertilizer pattern back to the tire tracks and the spray pattern boom to boom.

 

To spray and spread at the same time: Set the spread pattern for twice the width of the spray. For example a Junior and Intermediate model has a spray width of 8 feet. Set the spread width to 16 feet and spread back to the tire tracks. The spray pattern will match boom to boom.

 

The spread thins or feathers at the outer edges, eliminating sharp “edge of spread” lines which cause stripes and streaks.

 

Determine a dial setting on the low side. If setting is too low, cover the area more than one time. A higher setting can be used when a proven dial setting is established.

 

Travel at a constant speed.

 

Remember-Published dial settings are approximate only. Open the hopper door after the spreader is turned on at operating speed.
