THE DEVELOPMENT OF A TREE SYSTEM AND MACHINE FOR MECHANICAL HARVESTING OF APPLES BY THE COMBING TECHNIQUE

R.D. Child, M.J. LeFlufy
Hedgerow trees grown as 'fruit walls' were pruned to make them suitable for harvesting by a combing technique. The objective was to produce long flexible branches from a main stem no more than 2 m in height. SADH sprayed late in the growing season ensured regular fruit bud production and NAA-ethyl ester (Tre-Hold) was painted on pruning cuts to control upward growth in the tops of the trees. Harvesting was carried out using an over the row straddle-type harvester bearing long stiff fingers covered in foam polyether. At least 89% of Cox and 86% of Golden Delicious was harvested, but although there was little bruising, retention of the apples on the picking fingers was difficult.
