Tractor KENTAVR 404SDU
Tractor KENTAVR 404SDU — a powerful durable four-wheel-drive tractor for tough tasks KENTAVR 404SDU is a reliable tractor with a 4‑cylinder diesel engine rated at 40 hp and full 4×4 drive. It is built for heavy field work and agricultural tasks that require maximum productivity and endurance. The lack of a cab is offset by a robust construction and ease of maintenance. Engine A KM490VT diesel engine with 4 cylinders and a displacement of 2545 cm³ is installed, operating at 2300 rpm with direct fuel injection. The cooling system is liquid, with forced circulation and an expansion tank. Air intake preparation is through a metal mesh and an oil bath with a monotocyclone. Air preheating is provided by an electric torch spiral for easier starting in cold weather. A 35 L fuel tank provides long autonomous operation. Fuel consumption level — ≤245 g/kW·h. Transmission and chassis A mechanical gear transmission with 4 forward speeds, neutral and 1 reverse, supplemented by reduction and overdrive gears, allows precise speed adjustment from 0.39 to 31.97 km/h. Front axle with disconnect capability, rear drum brakes, differential lock and hydrostatic steering with a quick-turn handle provide high maneuverability and controllability on any soil. Ground clearance — 310 mm, agricultural clearance — 390 mm. Construction and hitch system The rear 3‑point hitch with hydraulic lift has a maximum lifting capacity of 550 kg and is equipped with a three‑section hydraulic distributor. The hydraulic system includes two external hydraulic cylinders and a separate gear pump. PTO has standard speeds of 540/720 rpm, allowing connection of a wide range of implements. Front hitch is absent. A detachable pendulum hitch is provided for towing. Comfort and electrical equipment It has a suspension seat with fore‑and‑aft adjustment to the steering wheel. The instrument panel is combined with analog gauges and indicator lights. Electrical equipment: 750 W generator, 12 V / 100 Ah battery, main front and rear lights, and a protected socket for trailer connection. A horn and hazard warning lights are present for safety.
