TY - JOUR T1 - English Techniques in Large Tree Transplanting JF - Arboriculture & Urban Forestry (AUF) SP - 90 LP - 93 DO - 10.48044/jauf.1982.022 VL - 8 IS - 4 AU - Chris J. Newman Y1 - 1982/04/01 UR - http://auf.isa-arbor.com/content/8/4/90.abstract N2 - Increases in gas prices in England during 1974 induced Civic Tree Care Ltd. to develop mechanized transplanting of large trees in multiple loads for economy of transport. The Newman Tree-Porter system brought many other benefits; one small machine using a hydraulic hammer drives curved blades to dig 7 sizes of ball from 32″ up to 80″; good performance in hard, stony or frosted ground; improved tree survival, and extension of planting season; low capital cost and low maintenance; versatility for digging and planting in awkward places. Tree-Porter augments Civic Tree Care’s long established Newman Trailer transplanting of larger trees with 90″, 100″, 120″ balls hand-dug and mechanically wrapped with Newman Frames. ER -
