3-point linkage support chain
Fig. 26.
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. 26a
). Then the mower has to be lifted with
hydraulic 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 more
than 1'4" above the ground, adjust the chain.

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. 27
