ATTACHMENT OF SCRAPER BLADE AND CONNECTION OF HYDRAULIC
COUPLINGS
Attach the scraper blade to the three-point linkage. Using the top link, adjust the scraper
boom as parallel to the ground as possible.
Connect the hydraulic hoses with the tractor’s hydraulic system (hydraulic models). The
scraper blade has two, four or 6 hydraulic quick couplings, which should be attached to the
corresponding couplings of the tractor. The coupling of the hoses defines the turning
direction when the auxiliary hydraulics control lever is moved. If you find the turning
direction of the blade or the boom to be illogical when you move the auxiliary hydraulics
control lever just change the coupling of the corresponding hoses.
Check the functioning of the hydraulics before starting operation. If the hydraulics is
inoperative, check the compatibility/connection of the quick couplings and the functioning
of the tractor’s hydraulic system.
Make sure that the hydraulic hoses do not get overstretched in any position of the
attachment and are not in a position where they can become entangled during the
operation of the machine and the attachment.
Always observe the safety instructions in paragraph 3 when coupling the attachment.
OPERATION
Scraper blades with hydraulic movement enable adjustment of the slew angle of the blade
and the lateral movement of the boom, depending on the model. Furthermore, the position
of the scraper blade can be changed by adjusting the lifting arms and the top link. The
attachment is operation by a lever of the single-action lifting device.
The positions of hydraulic scrapers can be adjusted from the tractor’s cab.
The blade can be slewed as follows:
Turn the blade using the cylinder (if the output of the tractor's hydraulic pump is low,
increase revolutions) until the cylinder is at its shortest.
Move the hydraulic valve control lever in middle position - now the blade crosses the so-
called “dead point”.
Push the control lever to the opposite direction to continue the movement (turning) of the
blade.
