Working preparation

Important recommendations

• Before working, check the condition of all parts and retighten nuts and bolts,

especially the ones on the disc gangs, otherwise the axis and other fixation components

may be damaged.

• Lubricate all grease fittings appropriately. (See lubrication instructions on pages 26

and 27).

• The drawbar spring must be adjusted

leaving 1 cm (one centimeter) of thread above

the nut and locknut in the rod. This adjustment

must be kept during working and transportation.

• To transport the harrow to longer

distances, it is necessary to use the

transportation lock (A), which is coupled to

the hydraulic cylinder rod.
