New Generation Picking Head
      New Generation Picking Head – MK2
    Features :-
• Full floating head;
• Tiltable and self aligning;
• Has a ‘soft pick’;
• Hydraulic, symmetrical
  width adjustment – 10”;
• Easy setup to suit
  canopy, yield & variety;
• Variable speed settings,
  from 0 - 550 rpm;
• Extremely robust
     New Generation Picking Head – MK2
  Head Timing :-

• pre-set in the URM
• should not need to be
• left and right sides linked
  by a central drive shaft;
• ensures both sides
  operate simultaneously.
    New Generation Picking Head – MK2
  Head Timing :- If the driveshaft has been removed.
  The timing can be checked using these procedures:-

• Turn the Left side Drive-
  line by hand until the
  locking plate and hole are
  in the correct position
• Use a bolt to “Lock” the
  left drive-line in place.
  New Generation Picking Head – MK2
Head Timing :- The picking head is correctly timed when
the key-ways in the eccentrics are facing as illustrated.

• Manually turn the drive
  line over slowly,
    New Generation Picking Head – MK2
  Drive Line :- For fine-tuning, if necessary, it is possible
  to manipulate the coupling in the vertical drive-line.
• The coupling can be split
  - allowing the vertical
  drive-shaft to rotate.
• The sprocket can now be
  moved in either direction,
  1-tooth at a time.
• Ensure the chain joiner;
  covers; etc, are securely
  re-fastened before
  operating the machine.

  Drive Link Adjustment :- the design has the ability to
  change the movement of the picking rods front and rear.

• Some grape varieties
  can prove difficult to
• Increasing the RPM
  of the head.
• Adjusting the width of
  the finger gap.
    New Generation Picking Head – MK2
  Finger Carriers :- It is important to ensure the Finger
  Carriers are set, and maintained, at the correct angle.

• A template is supplied to
  visually check the finger
  carrier angles.
• The same template is
  used front and rear - by
  utilizing opposite ends.
    New Generation Picking Head – MK2

• The angle is adjusted by
  changing the length of the
  adjacent turnbuckle.
• Remember to re-tighten
  the locknuts afterwards.
• Note: the angle is greater
  on the front carriers.
    New Generation Picking Head – MK2
  Through Passage :- The design offers ‘symmetrical’
  movement, for adjusting the through passage width.

• The profile width of the
  vine canopy can vary
• The through passage
  width is important for soft
  fruit removal & minimizing
  vine damage.
• Available hydraulic width
  adjustment of 125 mm,
  (5”) each side.
     New Generation Picking Head – MK2
  Angle Adjustment :- The picking head has adjustment
  for setting the angle of the picking rod banks.

• Turnbuckles at the top
  allow the operator to
  “angle in” the sides.
• Important: with the sides
  angled, the available
  width adjustment is less.
• If the Head is spread too
  far, the timing drive shaft
  may separate.
  The width adj. may be as
  low as 80 mm.
    New Generation Picking Head – MK2
  Picking Rods :- This new picking head is only available
  with - 3 ft spacing, Long Bow Rods.

• Bow rods are used in a
  short stroke; higher
  speed; mode of picking.
• The rods holder spacing
  is infinitely variable.
• Factory set at 4" spacing,
  inter spaced between left
  and right-hand sides.
• Tool supplied for this

  Maintenance :- Regular maintenance and checking is
  essential to ensure reliable operation and performance.

• Never work on the           • Wash with fresh, clean water

      Maintenance :- Regular maintenance and checking
is essential to ensure reliable operation and performance.

                          The chain cover needs to be removed
                          and lubricated every 100 hours
