Three harvesting machines matched to your farm size — from an 8 kg manual harvester for small plots to a 60/120 HP reaper-cum-chaffer that feeds large CBG plants.
Napier grown on a 45-day cutting cycle needs the right harvester for your scale. Cutting the crop before it fully matures keeps it tender, and every machine below fells the grass in a clean line on the field for easy collection — no special line-plantation required.
Our most economical harvesting method — a petrol brush-cutter with special cutting-blade attachments, weighing just 8 kg. The weight is balanced between the engine and the front cutting blade, so the operator handles it easily and cuts without fatigue. It cuts 2 tons/hour on only 750 ml of fuel — the cheapest confirmed harvesting cost.
Best where the daily requirement is below 10 tons and the Napier farm is under 5 acres — not for large biomass plants. It uses a high-quality 2-stroke 43cc or 53cc engine, essential because the RPM drops from 8,000 to 2,500 within 2 seconds during cutting, placing heavy load on the connecting rod. Even 10-foot, irregularly planted Napier is harvested easily.

For farms of 10 to 20 acres that need around 20 tons/day, a tractor-run reaper is the medium-capacity choice. It harvests 5 to 7 tons/hour, handles Napier up to 10 feet, and fells all the grass in a clean line — so no special line-plantation is needed.
A 6 to 8 foot reaper attaches to any 30–50 HP tractor you already own — we recommend buying it as your own implement rather than hiring. After harvesting, the grass moves on to chipping and then fine chipping for easy digestion at the plant.

| Best For | 10–20 acre Napier farms needing ~20 T/day |
Large CBG plants producing 3 to 5 tons of gas per day need 50 to 80 tons of chopped Napier daily — impossible by manual or tractor harvesting. A self-propelled 60 HP (or 120 HP) reaper-cum-chaffer harvests up to 80 tons/day, covering a 6 to 10 foot width at 4–6 km/hour.
It harvests and chaffs simultaneously, collecting the chopped grass in an onboard tank of up to 1 ton. When the tank is full it loads directly onto a lorry that goes straight to the CBG plant for the fine-shredding stage. For easy running, the field should be laid out in ½ to 1 acre bund-free plots.
