4.8.2 Trailing Kit
The main operating characteristics are
identical to the mounted implement. The
drawbar may be attached to the tractor rigid
drawbar or the pick up hitch. Altering the
length of the drawbar top link (D) will raise or
lower the back of the frame to alter the draught
requirements and quality of work. The
drawbar top link may also be used to take
account of varying tractor drawbar heights.
Alteration of working depth is effected by
altering the length of the top link on each wheel
unit (F). Both wheel units must be set to exactly
the same length. Remember to check the
wheels for clearance after any adjustment.
The tie bars should NEVER be removed,
therefore should reduced depth still be
required when working at the limit of the tie
bars; the tines will need to be raised in their
clamps.
To adjust working depth proceed as follows: -
Raise the machine and drive forward onto
hard ground. Lower the machine fully to
eliminate pressure in the hydraulic system.
Retain the hydraulic lever in the ‘lower’ or ‘float’
position, then lengthen the adjusters to
decrease depth or shorten to increase depth
as required.
When entering work ensure that the transport
locking units are removed, then lower the
tines to the ground, draw forwards until the
correct operating depth is achieved. In work
the hydraulic cylinders (E) should be in the fully
closed position. To leave work, extend the
hydraulic cylinders so that the tines are clear
of the ground.
