Introduction to SCH 4MPS Series Sprayers
The SCH 4MPS series offers a line of efficient and versatile three-point linkage sprayers that are crucial for effective agricultural operations. Available in two models, the 4MPS and 4MPS/125, these sprayers are designed to fit seamlessly with tractor three-point linkages and are powered by a 12-volt diaphragm pump connected to the tractor battery for seamless operation.
Features of the SCH 4MPS and 4MPS/125
Capacity and Dimensions
The 4MPS model boasts a tank with a 70-liter capacity, while the 4MPS/125 model has a larger capacity of 125 liters. Both models feature a spray width of 2440mm (96 inches), ideal for covering large areas efficiently.
Performance
These sprayers are equipped with a pump that delivers 7 liters per minute at an operating pressure of 3.1 bar. The maximum fluid temperature that can be handled by these units is up to 54 °C.
Weight
The dry weight of the 4MPS is approximately 15kg, with a full weight of about 84kg. The 4MPS/125 is slightly heavier, with a dry weight of around 18kg and a full weight of approximately 150kg.
Accessories
Each model comes with a 4-nozzle spray boom, a hand lance for targeted application such as spraying weed killers on nettles and docks, and a 5-liter fresh water washing bottle. Quick release couplings make switching between the hand lance and boom simple and efficient.
Preparation for Use
Before using your sprayer, ensure it is correctly mounted on the tractor’s 3-point linkage, with the center link arm adjusted so that the tank is level. Connect the power lead to the tractor battery (Brown to positive +, Blue to negative -). You have the option to use either the hand lance or the spray boom:
- Hand Lance: Connect to the back delivery hose from the pump. The nozzle will provide a hollow cone spray.
- Spray Boom: Attach to the rear bracket of the sprayer and secure with a thumb screw. Position the nozzle approximately 400mm-500mm (16”-18”) above the ground.
Ensure the black delivery hose is securely connected to the boom fitting, and commence spraying with the on/off toggle switch. Allow the pump some time to eliminate any trapped air before expecting a consistent flow.
Safety Instructions
When using the SCH 4MPS sprayers, adhere to the following safety measures to ensure both personal and environmental safety:
- Keep the sprayer securely fixed to avoid accidents.
- Avoid using the sprayer near other individuals and ensure no one rides on the sprayer.
- Do not spray on windy days or use tar-based products.
- Ensure no spray contaminates food sources, rivers, or ponds.
- Strictly avoid inhalation of chemicals and wear appropriate protective gear.
- Always test the sprayer with plain water to familiarize yourself with its mechanism before using chemical solutions.
Maintenance and Troubleshooting
Maintenance involves cleaning the unit after use and protecting it from frost. In case of issues:
- Verify all connections and positions if the pump fails to operate or deliver.
- Check and clean hoses, filters, and nozzles as needed.
Conclusion
The SCH 4MPS sprayers are robust tools for efficient agricultural spraying, combining ease of use with efficient performance. With a choice between two capacities and equipped with essential safety features, these sprayers meet the extensive needs of modern farming operations, ensuring maximum productivity and safety.
