Description
The B-1 grader was a four-wheeled vehicle weighing 3.17 tons, built on the basis of the nodes of the GAZ-AA truck . The engine was borrowed from the car, as well as the front and rear axles . Hydraulic equipment and other components of the autorader were manufactured at the Paide plant. During the design process, a wooden frame was prefabricated, on which machine components were tried on and by which their relative position was adjusted. The grader was intended for the repair of dirt and gravel roads [2] [5] .

History
The construction of the Paide Mechanical Central Repair Shop began immediately after the city was liberated from German occupation in 1944, and construction was completed in 1946. In the same year of 1946, on the initiative of one of the leading Estonian mechanical engineers Arnold Volberg ( Est. Arnold Volberg ; 2.07.1900 - 07.08.1967), the design of the first Soviet motor grader began. Until then, all graders used in the USSR were trailed. The GAZ-AA truck was used as the base vehicle.
The grader received an index of B-1, where the letter "B" indicated the name of A. Volberg. The first copy was ready in 1947. In Moscow, under the Main Directorate of Highways ( GUSHOSDOR ), a commission was formed with the participation of which the grader passed the tests. The machine received a satisfactory mark, and permission was soon given for its mass production. The first batch was released in 1948. A total of 122 copies of the grader were made. On May 1, 1948, he was presented at a demonstration in Tallinn . By decree of the Council of Ministers of the ESSR No. 680 of July 18, 1948, the developers of the B-1 motor grader were awarded the Republican Prize [3] [5] .
The design of the grader was quite primitive, so Wolberg subsequently made efforts to improve it. In subsequent years, modified versions were created under the indices B-3 , B-4 , B-5 and B-6 , as well as the heavier B-8. In the 1950s, the production of the three-axis E-6-3 grader (alternative index B-6-3 ) began, followed by the diesel V-10 , which became the last B-series grader [1] [2] [3] .
