A butt reducing machine comprises axially spaced-apart support means (12, 13) which together form a support on which logs (7) may be placed in a position in which a butt end part (7') protrudes into the region above a mill (8), at the same time as a top end part (7'') is kept pressed against the support by a holding means (4) on an elevating carrier (3). The holding means (4) comprises two axially spaced-apart pressing members (17, 17') mounted on a common frame structure (18) which is pivotably connected to the carrier (3) in order to enable a simultaneous, flexible pressing of the two members (17, 17') against the log, independently of the shape of the log. The distance between the pressing members (17, 17') is somewhat smaller than the distance between the support means (12, 13) located next to the mill, whereby the pressing members are located in planes closely inside said support means (12, 13) during their contact with the log.
