FIELD: machine building.
SUBSTANCE: group of inventions relates to cutter-loaders. Cutter-loader includes a cutting drum with multiple cutting teeth arranged on the drum and a mechanism of the cutting drum rotation. Mechanism of the cutting drum rotation includes a power supply source, a cutter motor, a switch and a drive with controlled frequency. Switch has the first and the second states. First state electrically connects the power supply source and the cutter motor for operation of the cutting drum at the rate of cutting, a the second state electrically connects the drive with controlled frequency and the cutter motor for operation of the cutting drum at the rate of servicing, lower than that of cutting.
EFFECT: technical result is provision for rotation of the cutting drum of the machine at the rate of servicing.
