CORRELATING PRODUCTION OF ACCUMULATING FELLER-BUNCHERS

摘要: ABSTRACT The field performance of accumulating feller-bunchers reported in the United States and Canadian literature is reviewed. major variables affecting feller-buncher trees per productive machine hour (TPPMH) are average stand tree diameter at breast height (DBH), initial trees/ha (TPHA), accumulation (TPACC). correlation between these used to determine TPPMH as a linear function DBH only. Slopes ranged from -6 -25 TPPMH/DBH (trees/cm/h) for considered. Accumulating should be considered use stands with = 15 30 cm shear or saw two three times DBH.
