Check Chain Adjustment; Final Top Link Adjustment; Removing The Machine From The Tractor - Ransomes LH Serie Manual De Seguridad, Funcionamiento Y Mantenimiento

CHECK CHAIN ADJUSTMENT

1. Start the tractor engine and lift the machine fully by means of the tractor lifting quadrant lever.
2. Switch of the engine.
3. Adjust the tractor RH lift rod length to level the main crossbeam of the machine.
4. Measure the height of the crossbeam from the ground at each end to ensure the machine is level.
5. Adjust the length of the check chains so that there is a minimum of slack when the tractor arms are fully
raised. This will prevent excessive side swing of the machine when transporting.
NOTE: If external tractor check chains are fitted, they should be adjusted so that no part of the lift arms can foul
against the hydraulic pump or any of the fittings when the machine is in the cutting position. This will prevent
excessive side swing of the machine when transporting.

FINAL TOP LINK ADJUSTMENT

Before this adjustment can be made, the height of cut of all three units must be set accurately with the machine
on a level, hard surface (see page 23). The 'A' frame must be vertical.
On the area to be mown, make an initial cut of approximately 20 metres. Carefully examine the finish of cut
across the width of the swathe - it is likely that the 2-front units will be cutting lower than the rear unit. If
necessary, to obtain an even cut, extend the top link by 1½ to 2 turns.
IMPORTANT: Do not lengthen the top link by more than 3 turns; the need for adjustment in excess of this
indicates that the height of cut settings on the units were not equal initially.
Any subsequent changes in height of cut will not effect the length of the top link; but it is important that is the units
are set up by using spacers between the ground and bottom blade, the top link should be shortened to its original
length, ie. until the turnbuckle contacts the jubilee clip. After resetting the height of cut by this method, the top link
should again be lengthened by the same amount.
NOTE: Alternatively, the height of cut setting on the individual units can of course be adjusted slightly to obtain an
even finish without altering the length of the top link.

7.4 REMOVING THE MACHINE FROM THE TRACTOR ___________________________

To remove the machine from the tractor, reverse the
attachment instructions.
IMPORTANT
1. The stabilising pin (A) must be replaced over the
rear unit trailing arm (B) before the machine is
removed from the tractor 3-point linkage; this
ensures that the machine is stable when
removed from the tractor.
2 The stabilising pin MUST always be removed
from over the rear unit trailing arm for all mowing
and transporting operations.
REMEMBER: It is not necessary at anytime when assembling or removing the mower from the tractor to
dismantle, or disturb, any hydraulic pipe joints or components. should servicing be necessary during use, it must
be carried out by a trained service person.
