FERIC studied the productivity and effectiveness of directional-felling heads in tolerant hardwood selection cuts. The feller-directors proved capable of handling the demands of this type of operation, and delimbing quality matched or exceeded that achieved with feller-bunchers. However, the feller-director with the smaller carrier and low-capacity head encountered more difficulty than the larger head-carrier combination. Delimbing the stems using the feller-directors decreased productivity, but not enough to make the operation uneconomical.
