6.5. 3-point linkage support chain

a)
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. 34a). Then the mower has to be
lifted with hydraulic lift about 40 cm high (Fig. 34b). 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.

6.6. Adjusting conditioner

6.6.1. Adjusting clearance between conditioner screen and roller

(Models: KDTC 260 S, KDTC 300 S, KDTC 261 S/SL, KDTC 301 S/SL)
Depending on size and thickness of the mowing grass, there may be a necessity to adjust
the mask of 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 experience, in order not to
block the conditioner and not to activate friction clutch of PTO shaft. The way how the mask is
regulated is shown in Fig. 35.
