LOMON SD904-B Tractor with Air Conditioner — Overview and Specifications
Introducing the powerful and functional LOMON SD904-B mototractor with air conditioner — a solution for farmers, farm owners, and utility services that require reliable, economical, and comfortable equipment. This model combines a robust design, all-wheel drive, and modern components: a YTO engine, 4x4, efficient hydraulics, and an ergonomic cabin with air conditioning for productive work in hot weather.
Engine and Performance: The YTO YD4EZ90C1 engine is a 4-stroke diesel engine with 4 vertically arranged cylinders, a displacement of 4080 cm3, developing 90 hp (66.2 kW). The starting system is an electric starter; the cooling system is liquid, closed with forced circulation. The nominal fuel consumption does not exceed ≤225 g/kWh, ensuring economical operation even under intensive load.
Transmission, Chassis, and Off-road Capability: The 4x4 wheel formula and a nominal traction force of 22 kN guarantee confident movement on difficult terrain. The gearbox offers 12+12 gears for precise speed selection, and a dry, two-disc, constantly closed clutch provides reliable engagement. The rear differential lock enhances off-road capability. The main drive is direct, and the steering is hydraulic for easy maneuvering.
Braking System and PTO: Brakes are implemented on the secondary shaft of the gearbox with brake drums. The power take-off (PTO) shaft is rear, splined, with modes of 540 / 1000 rpm — suitable for a wide range of mounted and trailed equipment. A trailer connector (socket) is present.
Hydraulics and Mounted Equipment: The hydraulic system operates on gear pumps (NSH) — separately for the hitch drive and for power steering operation. The number of hydraulic outputs is 4. The lifting capacity of the hitch is 2500 kg, allowing the use of heavy implements and efficient execution of field or utility work.
Chassis, Wheels, Dimensions, and Weight: The tractor's ground clearance is 535 mm. Tire size: front 9.5-24, rear 14.9-30. Wheel track: front 1275-1355 mm, rear 1270-1480 mm. Overall dimensions (LxWxH) — 4050x1830x2850 mm. Curb weight — 3120 kg.
The model is equipped with everything necessary to perform a wide range of tasks: agricultural, communal, and transport. The comfort of the air-conditioned cabin makes the workday less tiring, and the technical characteristics provide reliable tools for increasing the productivity of your farm.
