OPERATING PROCEDURE
TIGHTEN ALL FASTNERS ON THE HARROW AND
TEST THAT THE DISC ASSEMBLIES ROTATE
FREELY.
RETIGHTEN DISC HARROW BLADE ASSEMBLY BOLTS AFTER
10-15 MINUTES OF OPERATING.
PICK THE HARROW UP OF THE GROUND BEFORE TURNING
WITH THE TRACTOR
ADJUSTMENT OF HARROW PEPTH
ADJUST THE ANGULAYITY OF THE TWO DISC GANGS, AND
THE HARROWING DEPTH WILL BE DEEPER ACCORDING TO
THE INCREASE IN ANGULARITY. THE ANGULARITIES OF
THE FRONT AND REAR GANGS SHOULD FIND THEIR LEVEL
ON THE SAME GRADUATED LINE, THAT IS, THE
ANGULATITY OF THE REAR DISC ASSEMBLY IS 3’
BIGGER THAN THE FRONT DISC ASSEMBLY.
TO INCREASE THE HARROWING DEPTH, THE DOWN
SUSPENTION POINT MAY BE ADJUSTED UPWARD AND THE
UP SUSPENTION POINTED DOWNWARD.
THE ADJUSTMENT OF THE CROSS LEVEL AND THE
LONGITUDINAL LEVEL
THE ADJUSTMENT OF THE CROSS LEVEL AND THE
LONGITUDINAL LEVEL OF THE HARROW CAN BE SOILED
THROUGH THE ADJUSTMENT OF THE SUSPENSION HANGING
ROD OF THE TRACTOR AND THE LENGHT OF THE
DRAWROD.
TO RAZE THE DEFLECTING HITCH
GET THE SUSPENTION DRAW ROD OF THE TRACTOR
LONGER, OR MAKE THE TWO DISC ASSEMBLIES MOVE IN
THE SAME DISTANCE IN THE OPPOSITE DIRECTIONS OR
DECREASE THE ANGULARITY OF THE FRONT ASSEMBLY SO
AS TO RAZE THE DEFLECTION HITCH
ADJUSTMENT OF SCRAPERS CLEARANCE
THE CLEARANCE BETWEEN THE SCRAPERS AND THE
CONCAVE SIDES OF THE DISCS SHOULD BE KEPT WITHIN
THE RANGE OF 1-8mm.
IF THE SOIL MOISTURE CONTENT IS HIGH, OR IF
THERE ARE MANY WEEDS ON THE LAND, THIS CLEARANCE
SHOULD BE AS SMALL AS POSSIBLE
MAINTENANCE
WASH THE BEARINGS AND THEN LUBRICATE THEM WITH
GREASE AND CHECK ALL FASTNERS.
