Mowers KDD are suitable for mounting on tractors with three-point linkage cat. II and III.
To mount the mower on tractor:
drive the tractor near the hitch of the mower,
install pins (

) of tractor's lower links (
Fig. 12
),
adjust position of the mower by means of upper link (
C
) and hangers (
W
),
once the mower is mounted, lift support feet and secure them with cotters,
connect the mower's hydraulics to hydraulic connectors on the tractor (see 5.1.1.),
mount PTO shaft (

) (
Fig. 12
). If needed, shorten the shaft as in 5.1.2,
connect control panel using RS cable to control box on the mower – for models equipped with
control. Place the connected panel in the tractor.
After the mower has been attached to tractor, check balance and steerability of tractor-mower
set. To do this, calculate to formulas given in the appendix or weigh the set, and then drive on the
scales only with front axis of the tractor (the mower must be in transport position – lifted upwards).
If the pressure on the front axis is at least 20 % of the whole set’s pressure, it means the set is
stable. If not, front axis should be balanced.
