Fig. 7 Adjusting the depth and distance of the tubular shaft: 1 - working depth adjustment pins with
stabilising plate; 2 - shaft arm fixing screw.
Fig. 8 Hydraulic adjustment of the roller: 1- cylinder, 2- beam with arm bracket, 3- cylinder bracket.
On machines with hydraulic adjustment of working depth, the working depth is set using
pawls located at the piston rod of the cylinder. As more pawls are folded, the operation
of the machine becomes shallower. In a configuration where none of the pawls are
installed, the machine is in its greatest working depth configuration. In (Fig. 10 and Fig.
11), the correct way of installing the subsequent pawl plates on the actuator and the
incorrect way of installing them are shown.
