Harvester Training 2004 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 construction. New Generation Picking Head – MK2 Head Timing :- • pre-set in the URM factory; • should not need to be altered; • 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.

New Generation Picking Head – MK2 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 remove. • 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 significantly. • 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 purpose New Generation Picking Head – MK2 Maintenance :- Regular maintenance and checking is essential to ensure reliable operation and performance. • Never work on the • Wash with fresh, clean water harvester unless – every ten hours. all controls are off; • Check and tighten all mounting/assembly bolts. the park brake is ON; • Check for oil leaks and repair PTO is disengaged immediately.
