| Compact Walking Tractor | 8–15 hp | Two-wheel drive; operator-controlled | ¥5,000–¥12,000 | Small plots and narrow field sections | Low purchase cost, simple maintenance, easy transport | Low working speed and limited traction in deep mud | Lowest entry price for light-duty work |
| Small Four-Wheel Paddy Tractor | 18–25 hp | Mechanical four-wheel drive | ¥18,000–¥35,000 | Small to medium rice fields | Good maneuverability, lower fuel use, suitable for wet soil | Limited lifting capacity for heavy implements | Strong balance between price and basic field performance |
| 25–35 hp Paddy Tractor | 25–35 hp | Four-wheel drive; mechanical transmission | ¥30,000–¥55,000 | Medium-sized rice farms | Versatile for tilling, puddling, rotary cultivation, and transport | Higher purchase and operating costs than compact models | Often the most practical general-purpose range |
| 35–50 hp High-Clearance Tractor | 35–50 hp | Four-wheel drive; adjustable agricultural wheels | ¥50,000–¥85,000 | Medium to large rice operations | Higher traction, greater implement capacity, improved field productivity | May cause greater soil compaction if tires and ballast are unsuitable | Good choice when several heavy implements are required |
| 50–70 hp Rice Field Tractor | 50–70 hp | Four-wheel drive; synchronized or shuttle transmission | ¥80,000–¥140,000 | Large farms and contracting operations | Strong pulling capacity and faster operation with wide implements | Higher fuel, maintenance, and transport expenses | Cost-effective mainly when annual utilization is high |
| Tracked Paddy Tractor | 35–70 hp | Rubber or agricultural crawler tracks | ¥90,000–¥180,000 | Very soft, wet, or high-risk muddy fields | Low ground pressure and strong flotation in deep mud | Higher purchase price and more specialized undercarriage maintenance | Worth the premium where wheeled tractors frequently sink |
