6.7. Adjusting pressure of the cutter bar using support springs
Adjusting pressure of the cutter bar comprises changing tensioning of support springs by screw.
❑ To reduce pressure of the cutter bar on the ground, at the same time it is required to increase
tensioning of the springs by tightening the screw (reducing the distance L between the screw head
and spring catch).
❑ Increase in pressure of the cutter bar on the ground is caused by reduction in tensioning of support
springs, and this is done by unscrewing the screw (increasing the distance L between the screw
head and spring catch).
❑ To keep the proper ground pressure of the cutter bar, please use the settings provided (Fig. 30).

6.8. Adjusting the space between tine conditioner’s mask and its shaft
(Models: KDT 220 S and KDT 260 S(SL))
Depending on size and thickness of the mowing grass, there may be a necessity to adjust the mask
of the conditioner. The higher and thicker grass, the bigger the space between conditioner’s mask and
its shaft should be. Proper adjustment should be based on the experience, in order not to block the
conditioner and not to activate the friction clutch of PTO shaft. The way how the mask is regulated is
shown in Fig. 31.
