BTB – 200
Special Features
Locations
Moving on water
The design of the snowmobiler allows it to move on water, swampy terrain, open and ice-covered water bodies. The snowmobile can be driven on water by rotating the wheels; optionally, the snowmobile is equipped with an engine-driven propeller. With the propeller the speed of movement on the water reaches 8 km/hour. The front wheels are used to change the direction of travel.
Extra low pressure tires
The BME snowmobiles use ultra-low-pressure pneumatic tires BEL-192 “BME” produced by JSC “Belshina” of 1400×750-610 dimension, which were specially designed for the BTB – 200 snowmobiles. The tires have been tested in the most difficult operating conditions:
traveling through waterlogged dry forest;
driving on thin ice;
driving on stumps and snags.
The design and characteristics of the tire provide high cross-country ability and buoyancy of the snowmobile. Such tires practically do not injure the topsoil due to low specific pressure on the ground (0.15 kg/cm2).
Body made of fiberglass
The body of the snowmobile is made of fiberglass and has a sandwich type construction with internal sealing to provide heat and noise insulation of the interior. The rigidity of the body is determined by its design and internal metal tabs.
Hinged hatch
A large hatch on the roof of the snowmobile will be appreciated by hunters and huntsmen.

Assemblies and systems
| Transmission and clutch |  |
Snowmobile is equipped with a 5-speed manual transmission + 1 reverse gear. The clutch is a single-disc, dry clutch with diaphragm compression spring and hydraulic release drive. |
| Transfer box |  |
Snowmobile is equipped with a transfer box with high and low gears and a lockable inter-axle differential. The front and rear axles are permanently driven and connected by an inter-axle differential that distributes torque between them depending on wheel resistance. To increase the cross-country ability of the snowmobile, the differential can be locked, thereby equalizing the speeds of the front and rear drive shafts. |
| Bridges |  |
Front and rear axle with self-locking wheel differentials. |
| On-board gears |  |
All wheels of the snowmobiler have on-board gearboxes, which are pinion reduction gears designed to increase torque at the wheels. |
| Propeller and propeller drive |  |
To maximize water crossing efficiency, the snowmobiler is optionally equipped with a mechanically driven propeller powered by the snowmobiler engine. When traveling on water, the propeller is lowered from the transport position to the working position by a pneumatic actuator controlled from the cab. |
Suspension of all wheels of the BTB snowmobiler is independent, on cylindrical springs with hydraulic shock absorbers. Suspension arms are attached to the frame through silent blocks. Lever travel is limited by stops.
Pneumosystem
The snowmobile pneumatic system performs the following functions:
parking brake control;
raising and lowering the propeller;
operation of the automated tire inflation system.
Tire inflation system
Automated tire inflation system allows the driver to adjust wheel pressure without leaving the cab.
Management
The system allows you to adjust the pressure in one or more selected tires at the same time.
By reducing the tire pressure, the tire contact patch can be increased and therefore the ground pressure can be reduced, thus increasing the ground clearance on poorly bearing soils. High pressure is more suitable for driving on hard surfaces.
Indication
The tire pressure is shown on the display. Within the operating range of 0.1 to 0.5 atmospheres the wheel is displayed in green, otherwise in red. Keep in mind that exceeding the specified tire pressure range may destroy the tire.
Using the inflation system it is also possible to supply air for external consumption, for example, to inflate the tires of another vehicle, or to inflate the wheel of a snowmobile in case of damage to the pneumatic line leading to this wheel.
Electrical system
The electrical system of the snowmobiler is powered from the on-board network with a nominal voltage of 12V DC. The main parts of the electrical system are interconnected by a system communication line, including +12V and 0V power supply buses, as well as a three-wire CAN-bus interface, which is used to transfer data on the status of individual parts of the system and the necessary control actions.
LCD display
The display provides information necessary to operate and maintain the snowmobile.

Backup start unit
The backup start unit is required to start the snowmobiler engine when the LCD display is not illuminated when the “mass” is switched on and the condition of the electrical system does not allow starting the engine in the normal mode using the ignition switch and controls. Emergency starting of the engine by the backup starter unit is possible provided that the starter, engine and battery are in good working order.

Winch
Thanks to the low power motor, the electric current consumption is significantly reduced. The winch is equipped with a modern sealed solenoid unit, the mechanical part of the winch and its electric motor are additionally protected against moisture, water and dirt.
The winch is also equipped with an ergonomic rubber wired control panel.

Interior
Driver’s seat
Proper seating prevents the driver from quickly tiring, the front driver and passenger seats have adjustments for closer/farther away from the dashboard, backrest folding and tilt adjustment. The head restraints are also height adjustable.
Control panel, driver and passenger seats
The snowmobile has two rows of seats, the first row has driver and passenger seats, the second row has four passenger seats. The second row of seats is accessed through the front doors with the backrests of the front seats folded down.
The backrests and double cushion of the rear seats are removable, which makes it possible to increase the luggage area if necessary.
Rear passenger seats
Ventilation & Heating
1 – side deflectors, 2 – windshield deflectors, 3 – heater air temperature control lever, 4 – heater damper position setting lever, 5 – lower deflectors.
For heating the passenger compartment the coolant of the engine cooling system is used, which passes through the heater radiator and heats the air passing through this radiator. The amount of heat entering the passenger compartment of the snowmobile is controlled from the dashboard by the heater fan speed switch and the heater air temperature control lever.
Outside air can enter the cabin through the air intake grilles located on the plastic housing below the windshields, through the sliding windows of the side doors, and through the hatch on the roof of the snowmobiler.
Duffel boxes
1 – duffel box on the front panel, 2 – duffel box in the underbody, 3 – duffel box in the front door, 4 – duffel box under the side rear seat, 5 – duffel box under the wheel arch.
The body of the snowmobiler has storage boxes located in the front panel, side doors, body bottom (providing additional buoyancy of the snowmobiler), rear part of the body above the wheel arches and under the side rear seats.
Luggage area
Access to the luggage compartment is through the rear door of the snowmobiler.
Taking into account the operating conditions, the floor in the luggage compartment is designed so that the snowmobiler interior can be cleaned by watering the floor with water from a hose that will flow freely through the open rear door.
Rear seat configuration
If it is necessary, the luggage compartment can be transformed into two sleeping berths using the backrests of the rear passenger seats.
