Using the rear control
External control buttons of the electro-hydraulic system
The rear control is used to connect and disconnect
implements. The lifting switching lever (1) on the EHR-B
electro-hydraulic control panel must be in position (b) or
(c). The designation symbols of buttons on both the tractor
fenders correspond to the movement direction of the
three-point hitch after their pressing. The movement only
lasts as long as the button is held.
Every use of the rear control causes blocking of the
control system and the 'Blocking cancellation' must be
repeated.

1. Lifting
2. Lowering
The movement only lasts as long as the buttons are held.
External hydraulic control buttons are
functional also without previous activation of
electrohydraulics even in case of electrohydraulics
blockage for the reason of possible failure.
Control the arms of the rear three-point hitch by
external electrohydraulics buttons only at the lower
half of arms lift.
C18N122
When handling the three-point hitch with the
external control buttons the operator must stand out
of reach of the connected implement to avoid being
caught or injured by the implement.
