Indication of EHR-B errors
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.

Control the arms of the rear three-point hitch by
external electrohydraulics buttons only at the lower
half of arms lift.
