A jackshaft and grain elevator arrangement is disclosed for agricultural combines. A grain elevator (60) has a housing (102) , a drive sprocket (62) within the housing (102), a driven sprocket (64) within the housing (102), and a chain (98) within the housing (102). The chain (98) is wrapped around the drive sprocket (62) and the driven sprocket (64), and a plurality of paddles (100) are attached to the chain (98). A shaft (90) is fixed to and extends through the drive sprocket (62) to drive rotation of the drive sprocket (62). A first pulley (92) outside the housing (102) is fixed to the shaft (90) to receive power from an engine of the combine and is configured to transmit that power to the shaft (90). A second pulley (110) outside the housing (102) is fixed to the shaft (90) to receive power from the shaft (90) and is configured to transmit that power to a first crop processing device.
