Pests and diseases can take a big share of a crop if they are not controlled in time. Spraying with a hand or backpack sprayer over a large field is slow, tiring, and the coverage is rarely even. A tractor-mounted spray pump covers wide fields quickly and puts the spray where it is needed, which means less chemical waste and better crop protection.<\/p>\n\n\n\n
This guide explains how the spray pump works, how to set it up and calibrate it, how to spray safely, and how to look after the machine.<\/p>\n\n\n\n

How the spray pump works<\/h2>\n\n\n\nThe high-pressure pump sits on top of the tank and runs off the tractor PTO.<\/figcaption><\/figure>\n\n\n\n
The Rattan Spray Pump is mounted on the tractor and driven by its PTO, so it needs no separate engine. The working is simple:<\/p>\n\n\n\n
\n
01<\/div>
Tank<\/div>
Holds the spray solution: water mixed with the pesticide or liquid fertiliser.<\/div><\/div>\n
02<\/div>
Pump<\/div>
The PTO turns the pump, which draws the solution through a filter and builds high pressure.<\/div><\/div>\n
03<\/div>
Nozzles<\/div>
Pressure pushes the solution out through the nozzles as a fine, even spray over the crop.<\/div><\/div>\n<\/div>\n\n\n\nThe hose reel keeps a long spray hose ready for spot spraying and orchards.<\/figcaption><\/figure>\n\n\n\n
Before you start: check the machine<\/h2>\n\n\n\n
Fill with clean water first<\/strong> and run the pump to check for leaks at hoses, joints and the pump.<\/li>
Filters:<\/strong> clean the suction and line filters. A blocked filter drops the pressure.<\/li>
Nozzles:<\/strong> check every nozzle sprays a clean, even pattern. Replace worn or blocked nozzles rather than poking them with a wire.<\/li>
Pressure gauge and regulator:<\/strong> make sure the gauge reads and the pressure can be set.<\/li>
PTO shaft:<\/strong> grease the joints and keep the guard in place.<\/li>
Boom:<\/strong> set the boom width and nozzle spacing for your crop. The Rattan spray pump has an adjustable boom width and nozzle spacing.<\/li><\/ul>\n\n\n\n
Calibrate with plain water<\/h2>\n\n\n\n
How much spray lands on each acre depends on three things: nozzle size, pressure and tractor speed<\/strong>. Calibrate with plain water before you mix any chemical.<\/p>\n\n\n\n
\n
Simple water calibration<\/div>\n\n
Fill the tank to a marked level with clean water.<\/li>\n
Set the pressure and pick the tractor gear and engine speed you will use.<\/li>\n
Spray over a measured strip of the field, a set length at your boom width.<\/li>\n
Measure how much water it takes to refill the tank to the same mark.<\/li>\n
Work out the litres per acre from the strip’s area.<\/li>\n
Adjust the speed, pressure or nozzles until you reach the water volume you need, and write the setting down.<\/li>\n<\/ol>\n<\/div>\n\n\n\n
How much chemical should you mix?<\/strong> Always follow the label on the product and the current recommendations from Punjab Agricultural University (PAU) or your local agriculture department for your crop and pest. Spraying more than the recommended dose wastes money and can harm the crop, the soil and you.<\/p>\n\n\n\n
Tips for even coverage in the field<\/h2>\n\n\n\n
Keep a steady speed and pressure.<\/strong> Any change alters how much lands on the crop.<\/li>
Keep the boom at the right height<\/strong> above the crop so the nozzle patterns overlap properly.<\/li>
Spray when it is calm,<\/strong> usually early morning or evening. Wind blows the spray away from the crop.<\/li>
Avoid spraying before rain,<\/strong> which washes the chemical off.<\/li>
Keep the solution mixed.<\/strong> Some products settle in the tank, so keep it agitated while spraying.<\/li>
Turn off the spray at the headland<\/strong> while turning so the same patch is not sprayed twice.<\/li><\/ul>\n\n\n\n
Safety while spraying<\/h2>\n\n\n\n
\n
Protect yourself and others<\/div>\n
\n
Wear gloves, a mask, goggles and full-sleeved clothes while mixing and spraying.<\/li>\n
Read the product label before use and follow its safety instructions.<\/li>\n
Mix chemicals in the open air, away from children, animals and drinking water.<\/li>\n
Do not eat, drink or smoke while spraying.<\/li>\n
Never blow through a blocked nozzle with your mouth.<\/li>\n
Bathe and wash your clothes after spraying.<\/li>\n
Keep empty chemical containers away from home use and dispose of them safely.<\/li>\n<\/ul>\n<\/div>\n\n\n\n
Cleaning and maintenance<\/h2>\n\n\n\n
\n
After every use<\/div>
Spray out leftover solution in the field as the label allows<\/li>
Fill with clean water and run it through the pump, hoses and nozzles<\/li>
Clean the filters and nozzles<\/li>
Grease the PTO joints<\/li><\/ul><\/div>\n
End of season<\/div>
Rinse the whole system thoroughly<\/li>
Drain all water from the pump and hoses<\/li>
Check hoses and seals for cracks<\/li>
Store under a roof, away from sunlight<\/li><\/ul><\/div>\n<\/div>\n\n\n\n
Common mistakes to avoid<\/h2>\n\n\n\n
\n
\u2715<\/span>
Skipping calibration.<\/strong> Too little spray fails to control the pest; too much wastes chemical.<\/div><\/div>\n
\u2715<\/span>
Using worn nozzles.<\/strong> They spray more than they should and the pattern goes uneven.<\/div><\/div>\n
\u2715<\/span>
Spraying on a windy day.<\/strong> The spray drifts onto other fields, water and people.<\/div><\/div>\n
\u2715<\/span>
Leaving chemical in the tank.<\/strong> It damages seals and can harm the next crop you spray.<\/div><\/div>\n
\u2715<\/span>
Spraying without protection.<\/strong> Pesticides can be absorbed through skin and breathing.<\/div><\/div>\n<\/div>\n\n\n\n
