If neces-sary, weight the front and check again (see § 4.3on pag. 22).Before moving to the work field, it is a good idea to con-sult the spreading tables (see § ?? on pag. ??) for thefertiliser to spread, then prepare the machine as shown.Below are all the instructions needed to prepare the ma-chine to work in the field.4.7.1 Working width adjustmentAdjusting the working width depends both on the adjust-ments to make on the fertiliser spreader and on the oper-ating mode during tractor use.The adjustments to make on the fertiliser spreader are:• adjusting the working height• choosing the spreading discs• adjusting the drop point on the disc.The working width also depends on the number of P.T.O.revs during spreading.Adjusting the working heightDANGER!All operations must be done exclusively with thetractor off, P.T.O. disengaged, parked withparking brake and with the key removed.After having hooked the fertiliser spreader to the tractor(see § 4.1.1 on pag. 20) position it on even ground. Then:1. Check the spreading tables for the fertiliser to spread.If the fertiliser you are using is not shown in the ta-bles, consult the spreading table for a fertiliser withsimilar chemical and physical features (granulometry,specific weight) for the preliminary adjustments.2. Choose the working width from column (A) in figure4.14 then find the machine adjustment height fromthe ground in column (E).28- EN Cod. F07011577
