32 feet of boom, 21 nozzles and a 500-litre tank on an HTP triplex pump: even spraying for maize, cotton and gram in Karnataka, supplied factory-direct from Ahmedabad.
Sunidhi Agrotech Pvt Ltd manufactures the SAT-B501 tractor boom sprayer at its plant in Kuha, Ahmedabad, and delivers it anywhere in Karnataka. A 500-litre tank feeds an HTP triplex pump driven by the tractor's 540 RPM PTO, and the pump pushes spray through 21 nozzles spread across a 32 ft folding boom. Because a triplex pump has three plungers, pressure stays steady and the droplet size stays even from the first nozzle to the last. It mounts on a standard 3-point linkage and needs a tractor of 35 HP or more. Karnataka grew 1.91 million hectares of maize, 0.68 million hectares of cotton and 0.68 million hectares of gram in 2024-25, and 50,195 tractors were sold in the state in 2023-24. Nozzles are replaceable to suit the chemical and the crop. The price starts at ₹85,000 factory-direct (₹85,000–₹1,20,000), with a 1 year warranty from delivery; transport is charged separately at actual cost by distance.

Wheat, soybean and mustard are sprayed at fixed growth stages, often across large blocks, so the limit is how much ground you can cover before the window closes. A 32 ft boom covers a wide strip per pass and a 500-litre tank runs a long stretch before refilling. Spray in the early morning or late afternoon, when the wind is down, to keep chemical from drifting off the field.

In Karnataka, farm machinery subsidies are applied for through the state Agriculture Department through Raitha Samparka Kendras. The central Sub-Mission on Agricultural Mechanization (SMAM) publishes schemes and registered manufacturers at agrimachinery.nic.in. Subsidy amounts and eligibility change by year and applicant category, and most schemes need approval before you buy, so confirm the current terms with the agriculture department before placing an order.
