The adjustment can be made by adjusting the levelling disc s adjustment bolt Figure 3 item 1 The adjustment includes ten individual height positions The cultivation result is improved by completing repeated runs on cultivated soil In order to reduce the total width for road transport the levelling disc of the DiscMaster 400 model must be detached and placed in the transport mount In the DiscMaster 350 and 300 models it is advisable to place the levelling disc in the transport mount during road transport Figure 3 A idjusting tl the levi velling disc Multiva 4 4 Lateral adjustment of the disc shaft Upon significant alterations to the cultivation depth the rear disc shaft can be adjusted in relation to the front disc shaft in order to ensure even disc alignment E g When moving from uncultivated land to cultivated land Figure 4 presents the disc alignment with correct adjustments This ensures that the height of the soil strip between the discs measurement B is as low as possible AALAN A N AAA a A f Figure 4 Operation of the lateral adjustment as viewed from the front of the cultivator Factory adjustment is intended for a cultivation depth of 8 to 10 cm under normal conditions In shallow cultivation move the shaft to the left viewed from the back which reduces measurement A in Figure 4 Loosen the bolts and remove a sufficient number of adjustment pieces Tow the cultivator forward carefully
