Product Introduction

This Self-propelled Quick & Convenient Rice Harvester (25 HP, 12 Mu/Day Harvest Efficiency) is a dedicated solution for small-to-medium rice farms, family agricultural operations, and village-level machinery teams-designed to streamline rice harvesting with high speed and easy operation. It integrates three core functions (cutting, threshing, and cleaning) in one compact unit, eliminating the need for multiple machines or heavy manual labor. With a daily harvest capacity of 12 mu (≈0.8 hectares), it boosts efficiency 15x compared to manual harvesting, while its lightweight design (1,000 kg) and simple control panel make it accessible to novice operators. Compliant with global standards (GB/T 21961, CE, ISO 7258), it adapts to indica, japonica, and hybrid rice, as well as hilly or scattered small plots (slope ≤15°), making it ideal for Southeast Asian, Chinese, and African rice-growing regions.

Product Content Introduction

Self-propelled Quick & Convenient Rice Harvester (25 HP, 12 Mu/Day Harvest Efficiency) delivers exceptional "quick" performance with high harvest efficiency and low grain loss. Its 25 HP vertical 4-stroke diesel engine drives a 1.0 kg/s wet-rice feeding rate, enabling it to complete 12 mu of harvesting per day (working speed: 3.0–4.0 km/h)-covering the entire harvest of a 50-mu family farm in just 4 days. The axial-flow threshing drum (diameter: 480 mm, speed: 900 rpm) is optimized for soft rice straw, reducing straw breakage while achieving a threshing cleanliness of ≥98%. A combined wind-screen cleaning system (air volume: 1,000 m³/h, sieve area: 1.0 m²) minimizes grain loss to ≤2.5% (threshing loss ≤1.2%, cleaning loss ≤0.9%), ensuring maximum yield retention for farmers.

Self-propelled Quick & Convenient Rice Harvester (25 HP, 12 Mu/Day Harvest Efficiency) features a fuel-efficient, low-maintenance power system that enhances "convenience" for long-term use. The 25 HP diesel engine (brand: Changchai, a trusted agricultural power supplier) uses 0# diesel (summer) or -10# diesel (winter) with a fuel consumption of just 2.8 L/mu-35% lower than large-scale harvesters, cutting operational costs significantly. The engine's air-cooled design eliminates the need for a complex water cooling system, reducing maintenance tasks (e.g., no radiator cleaning or coolant replacement). A 150 L fuel tank supports 5+ hours of continuous operation, avoiding frequent refueling interruptions during peak harvest seasons.

Self-propelled Quick & Convenient Rice Harvester (25 HP, 12 Mu/Day Harvest Efficiency) boasts a compact, user-friendly design that simplifies operation and transport. Its overall dimensions (3,500 mm L × 1,600 mm W × 2,000 mm H) and 3.2 m minimum turning radius allow easy navigation through narrow field ridges (common in small plots) and U-turns in 1.5-mu fields. The ergonomic handlebar control panel has just 6 core buttons (start, harvest, adjust speed, clean, unload grain, emergency stop)-novice operators can master basic use in 10 minutes of training. For transport between plots, it is equipped with 6.00–12 road tires (max road speed: 15 km/h), eliminating the need for a separate trailer.

Self-propelled Quick & Convenient Rice Harvester (25 HP, 12 Mu/Day Harvest Efficiency) offers strong adaptability to diverse rice varieties and field conditions. It works seamlessly with indica rice (straw height 70–90 cm), japonica rice (90–110 cm), and hybrid rice (100–120 cm), and tolerates rice moisture content of 15–30%-operating normally even for slightly wet rice after rain. Its 300 mm ground clearance avoids damage from field stones or stubble, while its ≤15° slope tolerance makes it suitable for hilly regions (e.g., southern China, northern Vietnam). The 200 L grain tank reduces unloading frequency-one full tank holds grain from 1.0–1.2 mu of rice, so farmers only need to unload 10x per day for 12 mu of harvest.

Self-propelled Quick & Convenient Rice Harvester (25 HP, 12 Mu/Day Harvest Efficiency) prioritizes easy maintenance and operator safety to support long-term reliability. Key wear parts (threshing teeth, cutting blade, sieve mesh) are modular-each can be replaced in ≤15 minutes with basic tools (included in the accessory kit). A large 450 mm × 350 mm maintenance door on the side allows quick internal cleaning (critical for preventing mold growth in humid climates). Safety features include an emergency stop button (response time ≤0.5 seconds), protective covers for the threshing drum and fan, and anti-slip footrests-meeting CE (EN 13306) and CCC safety standards. It also comes with a 1-year warranty for the engine and main components, providing peace of mind for small-scale farmers.
