Adjusting The Cutting Height; 3-Point Linkage Support Chain - SaMASZ KDTC 260 Operator's Manual

Fig. 16. Swath widths of SaMASZ disc mowers. By combining discs and forming drums, different
swath widths can be reached.

6.4. Adjusting the cutting height

By means of upper link S (Fig. 9) adjust the cutting height. Extending the
link S increases the cutting height and shortening the link reduces it.
Cutting height is shown by the scale placed on the 3-point linkage frame
(Fig. 17), recommended height is 6÷7 cm.

6.5. 3-point linkage support chain.

Fig. 18. Support chain.
Support chain is used to ensure 3-point linkage frame of the mower is always at the same height, to set
the mowing unit parallel to the ground and to relieve the hydraulic lift of the tractor.
When connecting mower to the tractor, the hanger plate A of support chain should be disconnected
from chain and put on the pin B of upper link (Fig.18a). Then the mower has to be lifted with
hydraulic lift about 40 cm high (Fig.18b). The support chain is then connected to the hanger plate A,
so that it is tensioned when the mower is in its working position. If the 3-point linkage frame is more
than 40 cm above the ground, adjust the chain.
