2. Before making adjustments loosen the two sets of nuts and bolts (A and B) securing the deck levelling bracket (C) using a 13mm spanner and 13mm socket. 3. Then using a 13mm spanner, loosen (upper) locknut (D). 4. Now adjust the height by using a ratchet or spanner to turn the Nyloc nut (E) clockwise (up) to raise the deck or anti- clockwise (down) to lower it. 5. When level is achieved tighten up all nuts and bolts except E. For the closest cut, set the anti-scalp wheels in the middle adjustment holes. If you are experiencing scalping this can be minimised by setting the wheels in the lowest adjustment holes.

D E CB Deck Level Disk located underneath actuator Deck Levelling Bracket Page 11 Cutter - Drive BelDrive Belt Before carrying out tests or adjustments (the problem may be simpler) – first CHECK the following points: 1. Is the engine to cutter drive belt slipping? Check that the drive belt tension lever (fig 1) under the left running board is in the rear (tensioned) position. If not, rectify – this is the most likely cause. 2. Has debris collected in the cutter deck pulley housing (page 9)? If so remove the cover and remove the obstruction. ENGINE TO CUTTER DRIVE BELT TENSION The correct tension of the cutter drive belt (engine to deck) is critical. If incorrectly set it can lead to engine damage. To check the tension, follow this procedure: 1. Put the deck in a middle cutting height (position 5 on the HE illuminated indicator). 2. Select a midway position on the belt between the front (electric clutch) pulley and the rear (cutter deck) pulley and using a spring balance; apply a 2Kg (4 to 5lbs) pull (fig 3). 3. Using a ruler or tape, measure the deflection achieved which must be 13mm (1/2"). If more, the belt tension must be increased, if less – decreased. To correct the tension, follow this procedure: 1. Release the tension on the belt by pulling the belt tension lever forward (see fig 1). 2. Taking care not to burn yourself on the hot exhaust, locate the Trunnion at the end of the belt tension rod – lift the bonnet and look at the front (nearside) close to the exhaust. 3. Remove the spring clip and washer holding the Trunnion in place on the deck tension cradle (fig 2) and release the Trunnion so it can be turned. 4. Both the Trunnion and the belt tension rod are threaded. You increase belt tension by winding the Trunnion towards the end of the rod and reduce tension by winding in the reverse direction. 5. Having made the adjustment re-locate and secure the Trunnion, re-tension the belt with the belt tension lever – then re-check the belt tension.

As any such damage will not be covered by your warranty you may prefer that your dealer sets the tension. fig 2 fig 3 fig 1 De-tensioned Position Actuator Tensioned Position Deck Tension Lever Deck Tension Cradle Page 12 Powered Collector CONNECTION To connect the Powered Grass Collector (PGC) to the D18/50 tractor, ensure both are on an even surface with the locking levers (fig 3) on the collector facing the lift arms of the tractor. Move the collector manually to the tractor. Lower the lift arms using the auxiliary lift switch button (page 4) on the dash console. At the end of each lift arm you will find a locating lug. Slide the channels on either side of the PGC over the lugs but do not engage the locating lever yet. Ensure that the rubber flap at the opening of the PGC located on top of the transmission grass deflector. INSTALLING THE DRIVE BELT Place the drive belt over the PTO pulley (beneath the tractor seat). Standing adjacent to the tractor, extend the belt with both hands parallel to the ground. Now twist the belt to form a figure ‘8’ – the right hand up and the left hand down. In this position place the other end of the belt over the Powered Collector pulley. Be sure that this is installed the right way round otherwise the brush will ...
