landwyd landbou Hydraulic Heavy Duty Disc Harrows

THIS HYDRAULIC DISC HARROWS ARE MADE IN MEDIUM AND HEAVY DUTY MODELS.

THE DISC DIAMETER AND DISCS SPACINGS ARE DIFFERENT IN EACH MODEL.

THE TUFFY HYDRAULIC DISC HARROWS ARE WIDELY USED FOR LAND PREPORATION, LAND RE-NEWING AND EVEN THE MAKING OF FIRE BREAKS.

ANGLE ADJUSTMENT IS EASILY DONE BY LOOSENING BOLTS AND ADJUSTING TO THE CORRECT ANGLE THAT IS REQUIRED.

HEAVY DUTY OIL/GREASE BEARING UNITS ARE USED THAT CAN EASILY BE LUBRICATED.

SCRAPERS ON THE DISCS PREVENT BLOCKING OF SOIL AND MATERIALS.

OPERATION AND ADJUSTMENT

JOINTING

HITCH THE FRONT END OF THE LONGITUDINAL TRACTION BEAM TO THE TRACTION POINT TO THE TRACTOR DRAW BAR. THE TRACTOR SHOULD MOVE SLOWLY BACKWARDS WHEN HITCHING.

CONNECT THE FRONT END OF THE HYD CYLINDER TUBES TO THE TRACTOR REMOTES

OPERATING

CHECK TIGHTNESS OF ALL FASTNERS AND MOVEMENT OF ALL MOVING PARTS.

MAKE SURE DISC GANG NUTS ARE TIGHTLY FASTENED. REFASTEN AFTER 10-50 MINUTES OF FIRST OPERATION.

USE HYDRUALICS TO LIFT THE HARROW AND INSPECT ALL MOVING PARTS AND POSSIBLE LEAKS.GRIES DISC GANG BEARINGS BEFORE USE.

STRICTLY FORBID BACKWARDS MOVEMENT AND ABRUPT TURNING OPERATIONS

LIFT UP THE HARROW UP FROM THE GROUND BEFORE BACKING UP OR TURNING.

IN LONG DISTANCE TRAVELING, ENSURE THAT HYD GYLINDER SAFETY CLAMP IS FIXED.

TRANSPORT ADJUSTMENT

IN LONG DISTANCE TRANSPORTING, ADJUST THE SPRING LEVELLING DEVICE TO KEEP THE FRONT AND REAR PARTS OF THE HARROW BODY LEVEL OR KEEP THE REAR PART IN A HIGHER LEVEL TO ENSURE STEADILY TRANSPORTATION

ADJUSTMENT OPERATION

IN OPERATING ADJUST THE HARROW TO KEEP IT IN NORMAL WORKING CONDITION – PROPER HARROWING DEPTH AS REQUARED BY THE OPERATION.

THE FRONT AND REAR PARTS OF THE HARROW BODY IN A LEVELLED POSITION .

OR THE FRONT PART A LITTLE BIT HIGHER THAN THE REAR END OF THE LONGITUDINAL BEAM OF THE HARROW FRAME

ADJUST WORKING ANGLE OF DISC GANG

LIFT THE HARROW, LOOSEN THE JOINT BOLT CONNECTING THE HARROW FRAME AND DISC GANG BEAM AND REMOVE THE LOCATING BOLT.

THEN PUSH THE DISC GANG BEAM TO CHANGE TO CORRESPONDING HOLE TO ADJUST WORKINGANGLE OF THE DISC GANG.

DISC HOLE DEGREES

1 -14’

2-17’

3-20’

4-23

AFTER ADJUSTING THE WORKING ANGLE INSERT THE LOCATING BOLT INTO THE RELEVANT HOLE AND TIGHTEN IT AND ALSO TIGHTEN THE REST OF THE BOLTS

ADJUSTMENT OF THE WORKING ANGLE OF THE FRONT AND REAR DISC GANGS WILL INCREACE THE HARROWING DEPTH.

ADJUSTING HEIGHT OF THE GROSS TRACTION BEAM

REMOVE THE JOINT PIN BETWEEN THE CROSS BEAM AND HARROW FRAME, CHANGE THE LEVEL POSITION OF THE CROSS BEAM BY CHANGING THE HOLEWHERE

THE JOIN PIN INSERTED. ADJUSTING THE LEVEL HEIGHT OF THE TRACTION BEAM WILL AFFECT THE DEPTH OF FRONT AND REAR DISC GANGS – MOVING

THE HOLE POSITION UPWARD WILL INCREASE HARROWING DEPTH OF THE FRONT DISC GANG AND CONTRARILY

THE HARROW DEPTH OF THE REAR DISC GANG WILL INCREASE.
