5. The lever is used as a backup lever to put the cutting unit in either the transport or mowing position when hydraulic pressure is unavailable It can also be used to mechanically secure the cutting unit in the transport position The lever must be used when starting the engine if the engine stopped with the unit in the mowing position in order to raise the unit so that the start lock circuit is disengaged When the lever is moved to the transport position the blade brake is automatically activated so that the blades stop within about 5 seconds Transport position If the lever is pulled backwards the unit is raised and the blades automatically stop rotating transport position PRESENTATION Mowing Position If the lock button is pressed in and the lever is moved forwards the unit will be lowered and the blades will automatically start to rotate mowing position g pid If this does not happen it is probably because the unit has been lifted with the hydraulic lifting lever Lower the unit to the mowing position with the lever for the hydraulic lift Cutting height adjustment lever The cutting height can be adjusted to 7 different positions with the cutting height lever It is important that the air pressure in both front wheels is equal 60 kPa 8 5 PSI to produce an even cutting height Seat The seat has a jointed attachment on the front edge and can be tipped forward The seat can also be adjusted le
