FIELD: construction.
SUBSTANCE: invention relates to a two-rotor trowel, which can be used for processing concrete floors. The trowel for finishing the concrete surface comprises a rigid frame for placement on the treated concrete surface, an engine assembly attached to the frame and connected by a transmission with two rotor assemblies through two bevel gears, respectively, these rotor assemblies are connected to the frame adapted for tilting and are intended for frictional contact with the specified concrete surface and support of the frame on this concrete surface; the transmission includes a drive belt drive connected by a drive pulley to the engine assembly, and by a driven pulley to the input shafts of said gearboxes to transmit rotation to the rotor assemblies, whereas the transmission includes an intermediate shaft and an additional belt drive associated with the said gearboxes; on the specified intermediate shaft, the driven pulley of the specified drive belt drive and the drive pulley of the specified additional belt drive are fixed.
EFFECT: simplified design.
