A log on a surface of a translatable carriage against head blocks of the carriage is turned by rolling the log on the surface of the translatable carriage after releasing the log from engagement by reciprocating dogs that are carried by the head blocks and before advancing the translatable carriage toward a saw. The turning of the log on the surface is accomplished by engaging the log by a reciprocating dog that is carried by a pivoting arm at a location away from the engagement of the log by the reciprocating dogs that are carried by the head blocks. After turning of the log on the surface of the translatable carriage, the log is pushed along the surface of the translatable carriage back toward the head blocks by pushing against the log by spaced-apart double-acting cylinders that are mounted on non-translatable stands respectively.
