FIELD: agriculture. SUBSTANCE: method involves fixing three rollers on agrobridge girder for movement in vertical plane; fixing one roller with bottom width of 10-15 cm at midportion of agrobridge and axially fixing two other rollers with bottom width at least equal to width of carrier wheels or agrobridge caterpillar between midportions of wheels or self-propelled cart caterpillars; tightening wire on leveled ground and moving agrobridge over land so that intermediate roller is rolling with its midportion over wire, with agrobridge girder being permanently controlled for perpendicular position with respect to wire; after laying of first pair of tracks, transferring wire to adjacent plot and tightening wire on said plot in spaced relation with respect to its first position for distance equal to width of double track of agrobridge; laying following tracks. EFFECT: reduced material usage, decreased labor consumption in the process of laying permanent compacting ground tracks for agrobridge and compacted furrows. 2 dwg
