DISC HARROW OPERATING INSTRUCTIONS
Remember if you look after your machine it will look after you! Before using a new disc harrow check all nuts and bolts are tight and that the machine has been properly greased. All moving parts on the harrow linkage without grease nipples should be oiled once a day with old engine oil.
Important: After the first day’s work, re-check and tighten all nuts and bolts.
SCREW LIFT OPERATED WHEELS
Your harrow is fitted with a Screw Lift system to operate lifting and lowering of the harrow. Make sure the
threads on the Screw Lift are greased regularly. When lifting the harrow into the transport position make sure it
is in the fully raised position and not half raised as this will cause excess strain on the threads.
TYRE PRESSURE: 35 lbs per Sq. Inch
TRANSPORT BAR: This ensures that the harrow travels level when on the road. First hitch your harrow up to your tractor on a level piece of ground and raise the harrow into the transport position. Now check front and rear discs are approximately the same distance off the ground. If the front of the harrow is higher than the back then pin No.21 should be moved rearwards. If too low at the front the pin should be moved forwards. Before moving this pin the harrow should be lowered to the ground.
ADJUSTING GANGS LATERALLY: To shift front or rear gangs laterally, loosen the four clamping bolts and pull the
end of the gang frame. The harrow must be in the raised position.
ANGLE OF CUT: To alter the angle of cut there is an adjustment plate on the right side of the harrow frame,
both front and rear. To reduce the angle of cut, move front gang rearwards and rear gang forwards.
HARROWING: When you have lowered your harrow into the working position and you have started work, you can
only turn your machine to the left, never to the right as this may cause bearing failure or disc breakage.
HYDRAULIC OPERATED WHEELS
Your harrow is equipped with a double acting ram for raising and lowering the transport wheels. It is advisable to smear the ram shaft with grease if it is to be left outdoors for long period.
