Manual Seeder | Small gardens, hobby farming | Steel frame (1.2mm thickness, ASTM A36 compliant) ▲ Ergonomic TPR handle (reduces fatigue by 30%, OSHA tested) ▲ Adjustable seed spacing (1-5cm intervals, ISO 14272) | No electricity required (ideal for off-grid use) Compact & portable (fits in trunk) Low maintenance cost | Labor-intensive for large areas Slower seeding rate (≈50 seeds/min) Requires manual calibration |
Electric Seeder | Medium-sized farms, commercial gardens | 12V motor (150W power output) Automatic seed spacing (0.5-3cm, ±0.1cm accuracy) Adjustable planting depth (2-5cm) | Faster seeding (≈500 seeds/min) Consistent spacing and depth Handles large plots efficiently | Requires power source Higher upfront cost ($150-$300) Heavier (≈8kg) |
Semi-Automatic Seeder | Urban farms, small-scale agriculture | Hybrid manual/electric drive ▲ Seed hopper capacity (5kg) Depth control lever (ISO 6571 compliant) | Combines manual precision with electric speed ▲ Lightweight (≈4kg) Compact design | Moderate maintenance for hybrid components Less robust than fully electric models |
Hand-Crank Seeder | Raised beds, container gardening | Aluminum alloy frame (0.8mm thickness) Rotary seed disc (adjustable 0.5-2cm spacing) Low profile (height: 25cm) | Quiet operation (no motor noise) Ultra-portable (fits in backpack) Affordable ($30-$50) | Limited capacity (1kg hopper) Slower than electric models Requires physical effort for cranking |
Hydraulic Seeder | Large-scale farming, row crops | Hydraulic pressure system (200 PSI) High-capacity hopper (50kg) Variable rate control (GPS-enabled) ▲ | Ultra-fast seeding (up to 2ha/hour) High precision for large fields Automated calibration | Requires tractor attachment Complex maintenance Expensive ($1,500+) |
Pneumatic Seeder | Precision horticulture, greenhouse use | Air-driven seed delivery (CFM: 5-10) Micro-spacing control (0.1cm increments) Low residue (99.9% seed drop accuracy) | Perfect for delicate crops (e.g., lettuce, herbs) No soil compaction ▲ Minimal downtime | Fragile components prone to blockages Requires air compressor Less durable in harsh conditions |
