Greenhouse tractors are agricultural machines specifically designed for confined, high-humidity environments such as greenhouses and tunnels. Their basic features mainly revolve around adaptability, flexibility, power, and safety.
Structural and Dimensional Features
Low and compact body: To accommodate the limited vertical space inside greenhouses or tunnels, the overall height is usually controlled at around 1.1 meters (for example, the HaoTian TY350 has overall dimensions of 2700×1220×1100mm).
Small turning radius: The minimum turning diameter is generally less than 4 meters, with a turning radius under 2.8 meters, ensuring flexible U-turns in narrow passages.
Narrow wheel track design: The wheel track is adjustable or fixed at narrow specifications such as 970mm to avoid damaging crops or greenhouse frames.
Power and Operational Performance
Moderate power: Common power ranges from 20–30kW (approximately 27–40 hp), such as the HaoTian TY350 with a rated power of 25.8kW; traction force is usually between 6–10kN.
Flexible power output: Equipped with standard single/double-speed power take-off (PTO) shafts, commonly at 720 r/min, capable of driving rotary tillers, fertilizer applicators, sprayers, and other implements.
High passability: Four-wheel drive, differential lock, anti-slip tires, or track designs improve traction on muddy or soft soil.
Control and Safety
Flexible steering: Mostly uses front-wheel mechanical steering, with some high-end models supporting hydraulic assistance or intelligent control.
Safety features: Includes single-side brakes, differential lock, and anti-rollover capabilities with angles exceeding 20 degrees.
Low ground pressure: Track-type or wide-tire designs reduce soil compaction in greenhouses, protecting the plow layer.
Intelligent and Energy-Saving Trends
Intelligent control: New models integrate GPS navigation, automatic speed adjustment, and fault diagnosis systems to improve operational precision.
Energy efficiency and environmental protection: Equipped with Tier 3 or higher emission engines, fuel consumption below 310g/kW·h, and some models support dual-motor distributed drive to reduce energy consumption.
