Let the water flow: That’s no problem with the 750 litre maximum capacity of the HD200 sprayer and a range of different booms sizes to choose from. The HD200 is designed to work in combination with the John Deere ProGator for a great self-propelled sprayer solution.
The John Deere SelectSpray™ Series are the only sprayers in the golf industry to offer the choice of centrifugal or diaphragm pump to meet specific applications or operator preference.
Diaphragm pumps provide satisfactory flow rates but can achieve high pressure. Therewith the diaphragm pump is the right fit to operate a sprayer with intensive agitation system.
The 113.9-L/min (30.1-gpm) diaphragm pump provides plenty of flow for turf applications, but also can generate 20 bar (290 psi) of pressure. The pump is powered by a hydraulic motor and features a three-diaphragm configuration for excellent efficiency and smooth operation. The ability of this type of pump to handle thicker fluids, and its ability to run dry with no seals to fail, makes it a popular choice for tough spray solutions, such as turf paint.
Diaphragm pumps are positive displacement pumps, meaning that every revolution is going to pump fluid out of the pump outlet. As a result, a pressure relief valve is added to the main sprayer control valve assembly to protect the system if the system is dead-headed.
The relief valve pressure is adjustable up to 20 bar (290 psi), but should initially be set at 13.8 bar (200 psi). The spring-loaded relief valve opens a bypass line back to the tank when the system pressure reaches the relief pressure.
The pistons operate in an oil bath for long life and optimum lubrication. The diaphragms should be replaced annually or every 400 hours, whichever comes first. A standard suction strainer helps increase the life of the diaphragms by filtering debris out of the spray tank before it reaches the pump.
For exact application the automatic rate controller regulates the target application rate with variations in speed.
The automatic rate controller enable to spray in automatic mode or, if preferred, manual mode.
The automatic rate controller mounts to the operator platform of the ProGator™ and can be removed without tools for storage.
The system ties into the ProGator™ speed sensor, and adds a flow meter and digital pressure sensor to send a signal to the digital display to allow the operator to monitor speed, pressure, and application rate all on the same screen.
Units can be set in a variety of ways, including English, imperial, metric, and others, to allow users to read pressure, speed, and application rates in their preferred method.
Using the controller is easy. After turning on the controller, simply press the Pro button twice to enter the application setup screen. The application rate will be flashing. Any number that is flashing can be changed. Use the + and - buttons to set the application rate. Once the rate has been entered, press the Pro button and the pressure will flash.
The rest of the application setup mode is basically a calculator, which helps determine speed, pressure, and nozzle type. The calculator looks at the pressure, speed, and nozzle type to determine each variable's impact on the sprayer's ability to maintain the application rate.
As the application rate is entered into the controller, the pressure automatically changes as the application rate changes. For a given nozzle and speed, the pressure has to increase for a higher application rate, or decrease for a lower application rate.
If the user is not satisfied with the pressure required and wants a higher or lower pressure, use the + and - buttons while the pressure is flashing. The speed will change to show how much the operator must speed up or slow down to meet this pressure with the given nozzle.
Press the Pro button and use the + and - buttons to alter the speed and see its impact on the pressure required to achieve the target rate.
Automatic rate controller's nozzle display
One of the most innovative aspects of the automatic rate controller is that it allows the user to input the color of nozzle being used. Nozzle colors are an international standard and are the same for each manufacturer for a given flow rate.
Suppose the user is not satisfied with the pressure and speed needed to achieve a target rate. The nozzle color can be changed in the controller to determine if there is a better fit. Hit enter one more time and the nozzle selector will flash. Use the + and - buttons to select the nozzle type. This helps the user to select the right nozzle for the right application, and minimize chances of misapplication.
Hold the Pro button for 2 seconds to 3 seconds, and the controller will go back to the operating mode. The only value stored is the application rate; the others go back to zero.
The calculator serves as a guide for what speed needs to be targeted to get the application rate for the nozzle and pressure the operator would like to spray.
The automatic rate controller is chock-full of other features, such as a tank volume indicator, warning alarms, test speed modes, and more. A comprehensive list of all the features is described in detail in the operator's manual.
The intense agitation system in combination with the high-pressure diaphragm pump is key to prevent separation of the spray tank dilution.
By keeping the mixture of the dilution accurate and reliable during the operation period, the intense agitation system enables the best possible plant protection and supports environmentally friendly application.
The intense agitation system also supports the cleaning process of the spray tank.
The machinery must be designed and constructed to allow its easy and thorough cleaning without contamination of the environment and the operator.
The outside operation of the rinse system allows cleaning without direct contact between operator and spray tank. By removing any dilution deposition in the spray tank a low enough concentration will be reached to allow an environmental friendly disposal.
Who says sprayers are just for spraying? With the SelectSpray Series, the days of dedicated sprayers are a thing of the past.
Optional storage stands allow removal and installation of the sprayer in a matter of minutes. Spray in the morning, quickly change over to a cargo box for hauling cargo, and then spray in the afternoon. No tools are needed to make the change.
For added convenience, the storage stands have caster wheels for easy removal of the sprayer. The operator can easily position the sprayer and experience the value of the caster wheels when re-installing the sprayer onto the ProGator vehicle.
No need to get the ProGator perfectly positioned under the sprayer; instead, use the caster wheels to get proper alignment.
The sprayer can be removed from the ProGator in a matter of minutes.
First, pull the pin from the bottom of the control-box mounting bracket, and relocate the controller to the storage area on the back left-hand side of the sprayer.
Attach the controller to the bracket using the same pin. Leave the wiring harness connected to the controller.

Rear jack stands
Then use the hydraulics of the ProGator to raise the sprayer, install the front storage legs into their proper brackets, secure with the provided pin, and lower the sprayer onto the legs.
Then, install the rear jack stands using the pin chained to the jack. Rotate the handle to extend the jacks just far enough to relieve the pressure on the rear pivot pins.
Removing the rear pivot pin
Next, remove the rear pivot pins and the lift cylinder pin.
Disconnect hydraulic lines
Disconnect electrical connectors
Disconnect the rear quick-connect hydraulic lines, and the three electrical connectors at the rear of the machine.
Make sure the drain line is clear of the ProGator frame.
Driving ProGator away from sprayer
Then drive the ProGator away from the sprayer or pull the sprayer away from the ProGator.
The sprayer has now been completely removed from the ProGator and is ready to be stored while not in use. Installation is just as quick and easy the next time the operator is ready to spray.
It's about versatility, getting more for the money, and the design of the SelectSpray Series that helps make the ProGator one of the most versatile heavy-duty utility vehicles in the marketplace today.
The innovative electrical system design locates key components in one location on the machine. All fuses, relays, and lift/lower contactors are located in one convenient component box on the left-hand side of the machine. No tools are required to open the control box, leading to quick troubleshooting and component replacement.
When the sprayer is removed, the wiring harness remains with the sprayer—making changes between a sprayer and cargo box, or other attachments, a breeze. Only three connectors must be disconnected to remove the sprayer from the ProGator™ vehicle, greatly reducing removal and installation time.
The HD200 SelectSpray is equipped with impact-resistant polyethylene spray tank. The low-profile tank design is styled for excellent visibility to the outer boom sections and to the rear. The right-hand mirror coming standard with the sprayer supports the visibility to the right boom end. The direct mounting to the ProGator gives a low center of gravity for stable operation.
Exact fill gauge
The tank has a decal on the driver's side for reading the spray solution level, which is marked in graduated units. In addition, the European version comes with an adjustable exact fill gauge that shows fill rate from zero to full.
The low-profile design and offset filler neck product is easily loaded into the tank on the left-hand side of the machine.
A convenient basket strainer prevents large debris from entering the tank and can be easily removed without tools for cleaning.
The tank is equipped with a quick-fill feature, allowing the tank to be filled quickly anywhere it can be attached to a clean water source. This saves a lot of time by eliminating the task of traveling back to the original filling point every time the tank needs to be filled.
An anti-siphon feature on the quick-fill protects groundwater from unwanted chemicals.
For efficient pump flow and draining, the tank is sloped to a sump that allows for proper and complete draining when emptying the tank.
A vent line is also provided as standard equipment that runs to the top of the tank. The vent line also features a check valve that keeps chemical from exiting the tank.
