Stump extraction can be carried out in different ways, among which the mechanized removal is the most usual in the forestry sector. Information regarding the operation with cutting implements is important in the context of decision taking, operational and economic optimization of the activity. The objective of this work was to evaluate the operational performance and mechanized costs of different stump extractors implements in an eucalyptus harvested area. The work was carried out in an Eucalyptus urograndis clones harvested area where the treatments adopted for removal were the following: agricultural tractor + shredder head (T1), excavator + shovel bucket (T2); excavator + shredder head (T3), excavator + stump shear (T4) and bulldozer mat + stump pullers (5). The experimental design was the completely randomized, with four replications per treatment, where it was evaluated the operational efficiency (Ef), operational field capacity (Ofc), extraction productivity (Ps), hourly fuel consumption (Fch), hourly cost (HC), operational (OC) and by extracted stump (SC). For the conditions of the work, the T5 was the one with the highest Ef, Ofc, and Ps, lowest OC and SC.
