A baling press, having a cavity and a bolster for reciprocating in the cavity, uses replaceable cavity liners and bolster wear strips. These liners and wear strips can be replaced without disassembling the press by withdrawing the bolster from the cavity. Also disclosed is the use of a number of high volume pumps which are switched out of the hydraulic supply circuit as the bolster nears the end of its compression stroke so as to allow the use of relatively low power prime movers.
