Variable Cylinder Speed; Hydraulic Lift Levers; Unit Counterbalance Control - Ransomes Commander 3520 Bedienungsanleitung

6 CONTROLS
6.8 VARIABLE CYLINDER SPEED (B )
The speed of rotation of the cutting cylinders is
adjustable by means of the handwheel situated on
the right hand side of the operator to the rear of the
cutting unit lift levers. Rotate the hand wheel
clockwise to increase cylinder speed, anticlockwise
to decrease cylinder speed.
6.9 HYDRAULIC LIFT LEVERS (C,D,E)
The cutting units can be raised and lowered by three
control levers situated on the right hand side beside
the operator and can be operated as follows:
Centre lever (C) controls Centre and RH & LH front
Units No. 1,2,3
Right hand lever (D) controls R.H. Wing Unit No. 4
Left hand lever (E) controls L.H. Wing Unit No. 5
NOTE: If any unit is raised out of work then
lowered into work again the cylinder will not
rotate until the mow foot switch is depressed.
To lift: Move the lever(s) rearwards and hold in
position until the units are at the required height.
To lower: Move the lever(s) fully forwards and
release, the unit(s) will lower to ground level. DO
NOT hold lever in down position.
NOTE: The units will only lift and lower when
the engine is running.
IMPORTANT: If, when cutting, a lift control lever
is accidentally pulled up, the cutting units will
not float over ground undulations until the lever
is pushed fully down and allowed to return to
neutral again.
6.10 UNIT COUNTERBALANCE CONTROL (F )
Cutting unit ground pressure can be varied within
preset limits and is controlled by the handwheel on
the right hand side of the operators seat.
The handwheel is turned clockwise to reduce the
ground weight of the cutting unit and to improve
slope climbing performance.
The handwheel is turned anticlockwise to increase
ground weight of the cutting unit and this setting will
reduce the possibility of cutting unit "bounce" when
working at high speed on undulating ground. The
normal position for this control is midway between
the minimum and maximum settings.
