Page 178
1. Aggregation of the attached machines (loaders, bulldozers) is not related to the in- tended use of the BELARUS tractor. 2. No permit for joint operation of the BELARUS tractors with the mounted, trailed, semi-mounted and semi-trailed machines is required provided such operation com- ply fully with this Operating Manual for the tractor and does not fall outside the al- lowable framework of its use. -
Page 179
The BELARUS tractor can be aggregated with the machines having the rated resis- tance of the tools of 20,0 kN. The grasp width of the aggregate and operating depth depend mainly on the specific resis- tance of the soils, which determine the range of operating speeds with the account of agricultural requirements. -
Page 180
It is necessary to keep also in mind that the speed and operating depth are often limited by the agrotechnical requirements. The determination and assessment of the possibility of aggregation of the BELARUS tractor with agricultural machines shall be performed in several stages. -
Page 181
When purchasing the new machines to be used together with the tractor, it is necessary to specify the presence of the necessary working equipment providing for the possibility of aggregating with the BELARUS tractor of your model. For the machines located behind the tractor and driven from the PTO, it is necessary to order the cardan shaft of the necessary length and type, with the respective coupling di- mensions. -
Page 182
BELARUS-1221.2/1221В.2/1221.3 Aggregation Stage V Checking the possibility of motion of the tractor aggregated with the machine including checking the turn angles and maximum height of lifting of the mounted attachment until it rests against the tractor members, sufficiency of the length and free space of the cardan shaft when performing turns and transferring the machine to the transport position. -
Page 183
The main condition of the optimal aggregation of the BELARUS tractor is proper use of the engine power which is characterized by the load factor expressing the degree of use of the tractor’s rated power for performing the jobs by the aggregated agricultural machines. -

BELARUS-1221.2/1221В.2/1221.3 Aggregation chines, varying the grasp width, operating depth as well as motion speed in the process of the operating motion of the aggregate. If the efficient loading of the engine by varying the number of machines and operating speed is impossible, the respective partial operating mode should be chosen by reducing the fuel feed. -
