Engine Specifications and Powertrain Output
Punni multi-crop combine harvesters are powered by robust, water-cooled turbocharged 6-cylinder diesel engines (typically Ashok Leyland or Simpson powertrains) delivering 101 HP to 110 HP at rated 2,200 engine RPM.
This high-torque powertrain drives the cutter bar, rasp bar threshing drum, straw walkers, grain cleaning fans, and grain unloading augers simultaneously under heavy crop loads without speed drop.
- Engine power: 101 HP to 110 HP 6-cylinder direct-injection turbocharged diesel engine
- Cooling system: High-capacity radiator with automatic rotary dust cleaning screen
- Fuel tank capacity: 250 to 300 liters providing continuous day-long harvesting shifts
- Transmission: Heavy-duty mechanical gearbox with 3 forward and 1 reverse speed ranges and variable hydraulic speed drive
Threshing Mechanism and Cutter Bar Specifications
The harvester is fitted with a 14-foot (4.2 meter) floating cutter bar with hydraulic reel adjustment that accommodates laid crops and uneven field contours.
Its high-inertia rasp bar threshing drum, paired with an adjustable concave grid and five straw walkers, provides clean grain separation with minimal grain cracking and low harvest losses.
- Cutter bar width: 14 feet (4.2 meters) with heavy-duty knife sections and crop lifters
- Threshing drum: Rasp bar cylinder (typically 1,270 mm width) with multi-speed adjustment
- Separation system: 5 multi-step straw walkers with high separation surface area
- Grain tank capacity: Large grain hopper holding 2.0 to 2.4 tonnes of clean grain with high-speed discharge auger
Commercial Price Variables and SMAM Subsidies
Commercial purchase prices for Punni combine harvesters depend on drive configuration (standard wheeled drive versus rubber track drive for wetland paddy), cabin air-conditioning, and straw management system (SMS) attachments.
Under the Sub-Mission on Agricultural Mechanization (SMAM) and Crop Residue Management (CRM) schemes, eligible farmers and Custom Hiring Centers (CHCs) can obtain substantial capital subsidies through state DBT portals.
- Price determinants: Wheel drive vs half-track/full-track drive, Super SMS attachment, and operator cabin AC
- Track drive advantage: Rubber track models harvest waterlogged paddy fields without sinking or soil bogging
- Super SMS mandate: Straw Management System chops and scatters straw uniformly behind the combine
- Subsidy eligibility: Capital assistance under SMAM and state CRM schemes for custom hiring hubs

Common questions
What engine powers the Punni 777 combine harvester?
The Punni 777 is typically powered by a 101 HP or 110 HP 6-cylinder turbocharged Ashok Leyland diesel engine.
What crops can be harvested with a Punni multi-crop combine?
It efficiently harvests paddy (rice), wheat, soybean, mustard, barley, and pulses by adjusting drum speeds and concave clearances.
Why is the Super SMS (Straw Management System) attachment important on combine harvesters?
Super SMS chops loose paddy straw exiting the combine and spreads it uniformly across the field, allowing direct wheat drilling with Happy Seeders without field burning.
