The tractor "BELARUS-921" is a wheeled tractor of class 1.4 with all driving wheels, which can be used both in agricultural production and in industry.
The tractor "BELARUS-921" is an analogue of the tractor BELARUS-82.1, the main purpose of which is the performance of various agricultural works with mounted, semi-mounted and trailed machines and implements. In addition, they can be used to perform labor-intensive work in the unit with excavators, bulldozers, loaders, as well as special transport works and for the drive of various stationary agricultural machines.
The tractor "BELARUS-921" is designed to perform a complex of works on the cultivation of gardens and vineyards: work with a milling cutter, sprayers, the performance of a number of mechanized works in animal husbandry, distribution and harvesting of feed, as well as in industry, construction, municipal services and transport in a unit with mounted, semi-mounted and trailed machines and implements. Low-profile design makes it possible to perform work in indoor facilities with low doorways, is characterized by reduced overall dimensions and road gaps.
Advantages of the tractor "BELARUS-921":
- Low-profile construction (width 1550 mm, height 2450 mm), which makes it possible to carry out the work of indoor premises with low doorways;
- Underestimated center of gravity, which allows it to operate on terrain with complex terrain;
- Powerful engine 95 hp (turbocharged and intercooled air), corresponding to the environmental standards of EURO-2, EURO-3;
- Universal hydro-mounted system, the possibility of installing front attachments (in particular, the rotary blade OH-921).
The distinguishing features of the tractors "BELARUS-921" and its modifications from the BELARUS 900 series tractors are: installation of the front drive axle with a wheel angle of 55º; shortened sleeves and semi axles of the rear axle; Hydraulic system components with hydraulic lift, cable control hydraulic lift and distributor; cabin with shaped bent profiles and glued windows, molded upholstery cabin interior; plastic - hood, cab roof; hinged system with two vertical hydraulic cylinders; side control panel and hanging clutch and brake pedals; combined with the steering column instrument panel, etc.
The tractor "BELARUS-921" has a highly economical, easy-to-operate and maintain four-cylinder turbocharged engine of the Minsk Motor Plant, which ensures the implementation of the second stage of the European requirements for ecology.
The cabin is comfortable and provides safety, microclimate and noise protection, with ventilation and heated air supplied to the cabin, certified according to international ROPS / FOPS conditions. The cab is equipped with electric windshield wipers and windshield wipers and windscreen washer, equipped with rear-view mirrors, front and rear working lights, sprung seat, adjustable in height and tractor mass. All tractor control units are located in convenient areas. The change in speed from the slowed (1.8 km / h) to the maximum transport (35 km / h) of the forward stroke is provided by 16 steps in the gearbox. Accordingly - the reverse of 4.5 to 7 km / h - 4 steps. This allows you to pick up any agrotechnical speed of the units, depending on the type of work performed. Speeds are easily switched using synchronizers. Control is carried out by one gear lever.
When the clutch of the rear wheels is reduced to the ground or the tractive effort is increased, the front drive axle is automatically connected, which makes it possible to use the full mass of the tractor as a coupling, and, therefore, to provide high traction power. Hydrostatic steering provides easy and simple operation of the tractor for any job. The hydraulic lift provides power, positional and mixed methods of automatic adjustment of the rear attachment.
To increase traction and coupling qualities, a mechanical differential lock is provided.
On the tractor there are provided necessary traction-towing devices intended for aggregation with the whole complex of agricultural machines and implements.
For hinged and semi-mounted machines:
- Rear attachment (OU-2) with fast-connect devices. The carrying capacity of 4000 kgf on the suspension axis, which is provided by two power cylinders.
- front attachment (NU-2) with the carrying capacity of 1500 kgs on the suspension axis of the second category (under the order).
For trailers - towing device (TCU-1) - double cross-bar - with an allowable vertical load of up to 400 kgf.
Semi-trailers and trailers are aggregated through the towing device (TSU-1V) - traction fork (vertical load - 1200 kgf).
For farm machines with active drive there is a rear
