Hydraulic Rear Roller

The hydraulic rear roller is controlled either electrically by a switch on the control
panel or hydraulically by the via the control valve or independently by the tractor. If
electrically controlled the rear roller is either raised or lowered, there is no in-
between height control. If hydraulically controlled, the height can be set at the
required setting.

Note

To ensure the roller moves freely it's important to keep the roller linkage clean and
lubricated.
