Rotary drum mower for installation at top part of self-loading trailer for mowing e.g. green fodder from field, has conduits connecting inlet of pressure port and outlet port of motor for connection to hydraulic unit arranged on tractor

摘要

The mower (2) has a hydraulic motor (7) for rotating two drums (6a, 6b). Flexible conduits (8, 9) connect an inlet (10) of a fluid pressure port and an outlet port (11) of the hydraulic motor for connection to a hydraulic unit arranged on the tractor. A proportional distributor (20) controls a pressurized liquid flow supplied to the hydraulic motor and is designed as an electric drive. A varying unit (21) varies voltage or intensity of electric power supplied to the distributor for adjusting an opening of the distributor and comprises an electronic circuit. An independent claim is also included for a method for actuating a rotary drum mower.
