Operator's manual Light-class, rear disc mowerSAMBA- 19 - using the tractor’s lever, slowly lower the cutterbar to the horizontal position, unblock the lock and lower the mower until the cutterbar touches the ground, by means of upper link (S) (Fig. 9) adjust the cutting height. Extending the link S increases thecutting height and shortening the link reduces it. lower the mower's front guard.5.5. Preparing the mower for operationNOTICE:Before sale SaMASZ protects the cylinders with special grease against weather which maycause premature wear. Before operating the mower, remove the excess grease from thecylinders.Engaging the mower’s drive should be performed once the cutterbar is placed on the ground.The following should be performed in workplace and as mower is in operating position: Connect PTO shaft extension onto tractor's PTO shaft (if only one extension was taken out) orconnect the complete PTO shaft, Optimal angle of cutterbar in relation to the ground should be between 2° and 3°. This angle can beachieved by tightening or extending the link. The same principle applies to mowers equipped withconditioner or rollers, Slowly engage the mower drive until cutting discs reach their nominal PTO rotating speed of 500 ÷540 rpm, engage tractor gear and start mowing. Flat meadows can be mowed at driving speed of 8 km/h (5mph), however as unevenness occurs the speed should be reduced.IMPORTANT:If the pressure supporting the assembly of the cutterbars is too high, the cutterbars will not be able tolowered.NOTE:Too low a pressure in suspension disables the machine to be set in transport position. Iflocking pawl does not catch when mower is being switched to transport position, then increasepressure in suspension.NOTE:Improperly relieved cutting unit of the mower will cause increase of cutterbar pressure on theground which will lead to faster wear of sliding skids, overload of cutterbar, higher fuelconsumption, damage to the stubble and contamination of the fodder.5.6.
