Operator’s manual Rear disc mowersKDT- 30 -6.5. 3-point linkage support chainFig. 26. Support chainSupport chain is used to ensure 3-point linkage frame of the mower is always at the sameheight, 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 disconnectedfrom chain and put on the pin B of upper link (Fig. 26a). Then the mower has to be lifted withhydraulic lift about 1'4" high (Fig. 26b). The support chain is then connected to the hanger plate A,so that is tensioned when the mower is in its working position. If the 3-point linkage frame is morethan 1'4" above the ground, adjust the chain.6.6.

The higher and thicker grass, the bigger the space betweenconditioner’s mask and its shaft should be.

The way howthe mask is regulated is shown in Fig. 27.Fig. 27. Adjusting tine conditioner’s maskb)~1'4"ABa)+-
