“Tuman-3” retains the advantages of the previous models, “Tuman-1M” and “Tuman-2M”, while the payload has been increased to 2500 liters, and the new powerful engine can handle rough terrain more easily.

The device received a stylish modern design and a more comfortable and spacious cabin with panoramic windows for the best view.

Equipment

“Tuman-3” is powered by a new 71 kW (97 hp) turbocharged diesel engine.

The transmission is mechanical, five-speed from “GAZel NEXT A21R22” with synchronizers in all gears. Easily accessible for service as it is installed inside the frame between the rear and center axles. Wheel formula is 6 × 4.

Front and rear windows are made of triplex, side windows serve as emergency exits and are made of tempered glass. The cabin is covered by a heat-and-noise-insulating coating, equipped with a heater with a windshield blowing system, a ventilation system, a windshield washer, and a rear-view mirror. The air entering the cabin is filtered with a charcoal filter.

The narrow wheels allow for travel on public roads and for row spacing.

Low pressure tires minimize stress on both the soil and the machine, thus, allowing "Tuman-3” to reach a maximum speed on the rut up to 35 km/h.
